Hi list,

Is there a quick way to check if a group contains a specific control,
something like :
if there is a fld "xyz" in grp "abc" of this cd
I tried many things but it always generates an error.
So far, the only way I can think of is to maintain a custom prop
for each group, featuring a string that is the list of all controls
names of the group.

if you don't have any other controls with the same name,
you could check:
-> lineoffset("xyz",the childcontrolnames of grp "abc")



or, if you prefer:

if "xyz" is among the lines of the childcontrolnames of group "abc" then

NOTE: As mentioned, "xyz" would need to be a unique name for control in 
the group. If you have a field "xyz" and a button "xyz" (or 2 buttons or 
2 or more fields with the same name, etc.) this is not accurate.

I assume you mean can a programmer write an app in Livecode to extract 
test scores from a PDF and do something with them.


If the PDF has the test scores as text in the PDF (vs just a scanned 
image), then, yes, you can make a Livecode app that uses the PDF widget 
to open the PDF and retrieve the text from it and then parse that text 
for the test scores. If there is a routine pattern to the how the test 
scores appear, it will be easier to parse the text.

Re: Live LiveCode Create demo

[Paul Dupuis via use-livecode]

Just speaking for myself.

I use substacks for different windows (modal or nonmodal) in my 
application. A substack rarely has more than one card, which has the 
controls for that window laid out the way I want them. Also, substacks 
can just be script libraries or other sorts of libraries (icons, images, 
etc.)


So I already use substack as different layouts in native apps. If moving 
to the web, they effectively become different "pages" (or screens or 
layouts of controls)


I think I have 1 app where I still use multiple cards to store data, one 
record per card. If I have a chance to redo this, the data will be 
stored in a property or variable and the stack will have a single "card" 
or layout where the current record of data is displayed as the user 
navigates through it.


For the most part, I already think of a substack as synonymous with a 
window/screen/page layout of controls for an app.

My question is conceptual, not a technical/features based one, so I am raising 
it here because I would be really interested in folks views.

Kevin states towards the end of the video that substacks are still there and 
still work, but LC folks are moving away from that metaphor in favour of 
‘layouts’.  Now I had watched the whole video with my mental model being 
‘layouts’ correspond to a (very smart)  group on a card.   In light of what 
Kevin said that must be wrong, but I can’t quite see how the Create metaphor 
maps onto  the ol’ Xtalk hierarchy of things.

Re: A Windows weirdness

[Paul Dupuis via use-livecode]

I'm guessing here:

Paths on local Windows systems are typically 
driveletter:folder\folder\...\file.extension

Window scan use UNC paths, such as:

|\\Server2\Share\Test\Foo.txt|
||
When we had our first customer who was extensively using UNC paths, our 
software broke until we updated it to allow for both style of Windows 
paths to be handled properly.


Windows backslash \ gets converted to a / in most LC file paths (for 
example, the result of a open or save file dialog


Perhaps the IT did something to require only UNC paths and the // after 
the binfile had it look for a server rather than a local file?

failed to read some local data files.


It turned out that the issue was that I was reading the data as
put URL format("binfile://%s", tPath) into tData

this was working, but now returned "can't open file". Changing the 
statement to

put URL format("binfile:%s", tPath) into tData

fixed the issue, so it's fine. But my question would be does anyone 
know what would have changed on the system to make this statement, 
that used to work, do so no longer?

Cell colorization in a table in Livecode...

[Paul Dupuis via use-livecode]

My second color question of the day.

We current have a analytical view in our app which shows a table of 
frequencies. The number of rows and columns are driven by user data and 
can becomes a large number (I've heard all the arguments that users 
should not ever view tables of hundreds of rows by hundreds of columns 
as a person can't digest that much data - and our customer are quite 
clear that they want to view such data in this fashion).


We currently use a Datagrid. Each cell has a numerical integer value, 
0-n. We want to colorize the cells on a gradient, say from white to 
green (as an example) which we'd map the gradient colors with 0 being 
white and max(N) being green and color each cell accordingly.


This can be done relatively easily in the Datagrid by a small bit of 
custom code that looks at the cell value and sets the background color 
of the field (that is the cell) to the appropriate color.


We have been migrating all uses of Datagrids to Polygrids where the 
columns are driven by user data since the number of columns could exceed 
roughly 300, which at the default column width,  bumps up against the 
32,767 pixel width limit of the Datagrid. The Polygrid does not have 
this width limit, which is why we've been replacing Datagrids with 
Polygrids.


Now, our current problem is that there does not appear to be any tricks 
to having variable cell background colors in a Polygrid. Row colors: yes 
Alternate Row colors: Yes, Highlight color: Yes, possibly even 
highlighting different cell via the pgHilitedData property: maybe 
(haven't tested yet, but they'd all be 1 color).


I am not really familiar with the PolyList widget (vs PolyGrid). Has 
anyone figured out how to do a spreadsheet-like table in either the 
PolyGrid or PolyList with individual cell background coloring?


If not, I'll stick with the Datagrid and add a check for the columns x 
widths exceeding the 32K px threshold and just warn the researcher we 
can't handler that much data (which dings our product vs competition!)

If Paul’s post is not viable, I don’t think there is any native gadget

Re: Proposed update to datagrid library

[Paul Dupuis via use-livecode]

My Datagrid skills are not great, but i thought the thedgIndexes 
ofgroup"DataGrid" The Dictionary says "Returns the internal list of 
indexes in the order in which they appear in the data grid"
You also have the dgIndexOfLine[pLine] to get the index of the line 
(hilited line or next line or whatever). Then find the index returned by 
dgIndexOfLine in the dgIndexes, which will return a line number in the 
list of indexes and then add 1 to that to the the line in the dgIndexes 
of the next index.

Hi all.

Has anyone tried to determine the index of the next line of a datagrid? It’s 
not as straightforward as you might think. When data is first loaded into a 
datagrid, the dgIndexes are only going to be in numeric order if the sort order 
of the datagrid is the same as the data you are loading. Otherwise, the indexes 
will be all mixed up, but the dgLines of the datagrid will ALWAYS be in the 
order of the visible rows.

Sure you can just add one to the current dgHilitedLine, but what if you want to 
know the index of the next line just before deleting the current one? You 
cannot delete the line first because then the line numbers change, and there 
won’t be another line hilited until your code sets it.

And while there is a dgIndexOfLine property built in, there is no 
dgLineOfIndex! Not only that, but there is a dgIndexes property, but there is 
no dgLines property! How odd is that?? The goal is to determine the index of 
the next visible line where the line numbers are no longer sequential.

So I wrote some very simple virtual properties that ought to be a part of the 
datagrid library. You can put these in the script of a datagrid itself, or if 
you are brave enough to use the inline behaviors feature of datagrids as I do, 
you can put them in your own datagrid custom library. But really they belong in 
the built-in datagrid library itself. They are:

getProp dgNextIndexOfLine [tLine]
   put tLine +1 into tNewLine

   if tNewLine > the dgNumberOfLines of me then
  put the dgIndexOfLine [tLine] of me into tIndex
   else
  put the dgIndexOfLine [tNewLine] of me into tIndex
   end if

   return tIndex
end dgNextIndexOfLine

getProp dgPrevIndexOfLine [tLine]
   put tLine -1 into tNewLine

   if tNewLine <1 then
  put the dgIndexOfLine [tLine] of me into tIndex
   else
  put the dgIndexOfLine [tNewLine] of me into tIndex
   end if

   return tIndex
end dgPrevIndexOfLine

You are welcome. :-)

2018-03-27T17:46:39Z

I can output LC dates and times in any format, but I personally have not 
seen this format before. The "T" is obviously just a delimited between 
the data and time, but my question is the "Z" at the end? Is this just a 
delimiter or does it indicate time zone (and in "zulu" time, i.e GMT)? 
Or something else?


Anyone seen this timestamp format before and know the details of it?

Thanks in advance,

Re: .mp4 support in browser widget--Windows

[Paul Dupuis via use-livecode]

As customers once had to download and install Quicktime for Windows to 
use a wide variety of media in Revolution/Livecode Standalones under 
Windows (XP, 7, 8.x, 10, 11), when QT for Win became obsolete, we just 
switched to directing customers to download and install LAV Filters 
instead. They do this as a separate install, done by the end user. So 
far, this has not seemed to be an issue or inhibited adoption. It also 
does not run afoul of any licensing issues with embedding LAV Filters in 
a LC standalone.


Regardless, if you want media file parity with macOS on Windows in 
Livecode and do not want to wait for whatever dp version of LC 10 might 
have MMF in it, then you need to add a codec pack for DirectShow. There 
are other options for additional DirectShow codecs to LAV Filters. I 
can't recall any of them - just that we reviewed a bunch, most of which 
were commercial and required licensing. LAV Filters was reliable, 
functional, easy to install, and free. I'm not endorsing it for your 
application or anyone else's, just noting what worked for us.

LAV Filters appear to be distributed under GPL v2:
https://github.com/Nevcairiel/LAVFilters/blob/master/COPYING

This invites an interesting exploration of the boundaries of GPL 
rights/responsibilities inheritance: does distributing GPL components within an 
app require the app distributing them to also be GPL?


I've seen many cases the other way around, FOSS projects like Ubuntu where some 
users can benefit from prioprietary packages like NVidia device drivers. Ubuntu 
and others seem content to have resolved the issue by not including components 
with incompatible licenses in their distributions, instead providing links the 
user may choose to follow to install them.

But the case in this thread is the inverse, a proprietary system with embedded 
distribution of Free and Open Source components. I haven't seen this before, so 
I did a quick search to see how others have handled it.  Here are a few of 
those discussions:

"Is it legal to use GPL code in a proprietary, closed-source program by putting it 
in a separate, standalone program?"
https://opensource.stackexchange.com/questions/7078/is-it-legal-to-use-gpl-code-in-a-proprietary-closed-source-program-by-putting-i

"Distributing a proprietary application together with GPL software"

"Can I use GPL software in a commercial application"
https://softwareengineering.stackexchange.com/questions/47032/can-i-use-gpl-software-in-a-commercial-application

"Can I use GPL, LGPL, MPL licensed packages with my application and make it closed

"Can I use GPL libraries in a closed source project if only the output is 
distributed?"
https://opensource.stackexchange.com/questions/2338/can-i-use-gpl-libraries-in-a-closed-source-project-if-only-the-output-is-distrib


Spoiler: no one in those discussions has a definitive answer, but there is a 
general trend toward USING GPL components being viewed as okay but drawing the 
line at DISTRIBUTING those GPL components within a proprietary app.

And given both the rarity and the subtlety of details in such circumstancs, 
even the GPL FAQ more or less punts on this question:
https://www.gnu.org/licenses/gpl-faq.en.html#ManyDifferentLicenses


Of course I'm not an attorney, and even if I were I'm not contracted as your 
attorney, so nothing I write can be construed as legal advice.

But as someone who has a personal hobby of reading IP case law, and has contractual 
requirements in most of my professional work to demonstrate a reasonable good-faith 
effort to help my clients avoid potential risks with IP licensing, I tend to err on the 
side of "When in doubt, leave it out."

In cases where the best way to handle someone else's work is unclear, I often 
find it most useful to get clarification from the author of the work.  As the 
copyright holder, they would be in a position to grant, or deny, specific use

Re: .mp4 support in browser widget--Windows

There ARE methods to compress and store a 3rd party library or 
application as a property in a Livecode standalone and have the 
standalone on start up check (if there is a file ... or if there is a 
folder ...) for the app's presence and if not present, install it by 
uncompressing and writing it as a bnfile to the install location.


I don't know whether there are any Livecode lessons on the web site on 
how to do this or not or whether someone else who has done this may have 
code or tips to share.


First, you may want to manually install LAV Filters and see if it has 
the codecs for the media formats you want.


Livecode 10, before release, is supposed to get updated to use the 
Windows Media Foundation (and it's wide range of current codec for 
various media formats). This change (DirectShow to MMF) is not in the 
current (dp8) version. So a media coded pack (like LAV Filters) for 
DirectShow is your only option under there is a version of LC 10 that 
supports MMF.


If you set the way back machine, if you wanted to do media on Windows 
under old versions of Livecode (aka Revolution), you had to install 
Quicktime for Windows.

Re: eMail attachment: best practice?

[Paul Dupuis via use-livecode]

So this tsNet example for sending an email look great IF you are using 
it in an corporate or institutional setting. One where you have a known 
SMTP server and you know whether or not that SMTP server requires 
authentication.


However, in the "wild" of a distributed application that could be on any 
customer's computer in any setting, how do you know what the customer's 
SMTP server is or whether it requires authentication. If it does require 
authentication, most people set this up in their email client ONCE (or 
rarely) and may not know or remember what the credentials are.


So I considered using our company SMTP server, but increasingly, SMTP 
servers will reject messages if they are from a client computer that is 
not in the same domain, as is the case with ours (for 
anti-spamming/spoofing), so that it out as an option.


I kinda need a solution that uses the clients own email client (and 
server). Maybe I should look at how to encode the array in a pure text 
form that can be part of the email body and send it that way. The 
problem there is that some email clients (like gMail) limit the size of 
the message body that can be generated from their APIs. If you use 
revMail with someone with gMail as their default mail, the message body 
can only be about 2500 characters (or maybe 5000, I forget the exact limit).


I suppose I could output the array as an encoded file to the customer's 
desktop and ASK them to manually attach it to the generated email? I 
wish there was a better option.

eMail attachment: best practice?

[Paul Dupuis via use-livecode]

Under a specific condition, my app creates an email with some 
pre-populated information using revMail:


revMail address, [ccAddress, [mailSubject, [messageBody]]]

So, my call is: revMail tSupportEmail, , "Diagnostic Report 
Information", tEmailBody
Where tSupportEmail contains a valid email address and tEmailBody 
contain the information I want to send.


I realize the user still has to click their send button in their email 
client, but I have 2 questions:


1) I see the Dictionary still lists "revMailUnicode" with the same 
parameters. If tEmailBody contains Unicode characters do I need to 
textEncode(tEmailBody, "UTF-16") and use revMailUnicode OR is plain old 
revMail now Unicode aware


2) My more important question is how does one create an email with an 
attached file? I see no feature of revMail to include an attachment. Is 
there some other way? If there is no way to add an attachment, what 
might the best practice for sending the contents and structure of a 
Livecode array be?

Re: Survey: Would you buy one or more widgets from the PRO PACK separately?

[Paul Dupuis via use-livecode]

Of those listed, I would pay for (if I needed to, but I have the full LC 
that includes extensions) the PDF Viewer and, possibly, tsNet PRO


I do not develop for mobile, so mobile widgets are not of any immediate 
interest.

Hi friends,

Livecode is selling most of their widgets separately,
however not the ones from the PRO PACK:
Mobile Debugger
Script Profiler
tsNet PRO
mergAccessory
PDF Viewer

But unfortunately the PRO PACK is quite expensive:
328.90 Euro PLUS VAT!

I am sure most of you do not need all the widgets in the
PRO PACK, but maybe one or two of them.

So please just write if you'd like to buy one or more of these,
maybe we can induce LC to also sell them separately.

I confess that this is a quite selfish idea from me, I only
use the PDF Viewer widget in my freeware* app and the
app exclusively made for my band mates, three of us use
an iPad and two of us an Android tablet.

*It's actually "donationware", but noone donated any money
so far in the last couple of years. :-/

I bought the complete PRO Pack in the last three years,
although I ONLY need the PDF viewer, but cannot afford
this anymore. Especially since I do not earn any money
with my apps and I need to renew my Apple Developer
Membership in october.

I would LOVE to buy just the PDF widget separately!

Thank you for reading!

P.S.
Since Android browser cannot display PDF files out of the box,
this is no alternative for me.


Best

Klaus

You can use:

*click*at(rightofbtn1- 5,topofbtn1+ 5)

assuming the combo button is 'btn 1' on your card or replace btn 1 with 
a reference to your combo button. The idea is to generate a "click" at 
the location of the pulldown arrow part of the combo button.


You can create a new empty stack and place a combo btn on it and try 
line of code in the message box with the browse tool selected.

Re: somehow OT, but somehow not - no price information anymore on Livecode website

Pricing still seems to be available for Student and Educational plans:

For example, at https://livecode.com/education-plans/ under the "Buy a

(https://livecode.com/education-plans/#pricingoptions)


It is just Pros & Business they are looking to quote for, which is a

Re: Saving data in standalone

[Paul Dupuis via use-livecode]

You can save external stacks or created on the fly stacks where ever you 
have *write* (and read) permission on your OS.


Increasingly, whether macOS or Windows, that is not the Applications 
(macOS) or Program Files/Program Files (x86) (Windows) folders. I find 
the SAFEST place to save something is using 
specialFolderPath("documents") and then create a folder structure for 
your company or app in the user's Documents folder. OSes are becoming 
more and more "sandboxed" to prevent malware and dumb user mistakes from 
wrecking apps or the OS itself.

Re: Saving data in standalone

My suggestion would be to have your Standalone create a new stack with 
the user's work and save that stack under a customer file extension for 
your app.


You can not actually save data in a standalone. you must save it to some 
source outside of the standalone - and stack, a text file, a binary 
file, a remote database, etc. - whatever works for your app.

Hi list,
I am working on an app for a client who will use it as a standalone.
Basically users will be able to import data such as images, text and
even html from various sources. All these data will self organize in
different groups that the user will be able to select, move around
and organise in a layout, and finally export as a pdf file.
The problem is that all this work will be done in successive sessions,
and between each step there will be the need to temporary save the
work to retrieve it in the next session.
And I'm not sure about the best way to save groups within an LC
standalone and retrieve everything in a similar layout in the
next session, or even if it's possible.
Any idea and suggestion are welcome.

Thank you in advance.

Re: Livecode startup messages...

Yes,

I figured that out earlier this week and just hadn't had time to post. 
It is some sort of Windows 11 issue and not on all Windows 11 systems. 
Still don't know what it is. The 3 printers on our office network are 
all HPs and I think all my drivers are up to date. I also have a couple 
of different PDF printer drivers installed (Microsoft's, Foxit's and one 
other)

Interesting. As I’ve mentioned I install and provide IT support for

If you go to install a printer and you see a list of icons representing
the discovered printers on the network, NEVER EVER USE THEM! Manufacturers
will not support them, and they cause all kinds of issues. ALWAYS select
“The device I want isn’t listed” and use the standard TCP/IP method of
installing a printer, or better yet the manufacturer probably supplies an

Of course, that does not help LC devs who are deploying apps to end users

Epson and HP if I remember correctly.

The fix we added did fix the crash, but in some cases caused a delay on

Maybe there is a regression in some way that LC now does not crash but

shows the messages.

Could you try the following?

1. Open Windows Task Manager
2. Search for a process named "Spooler Subsystem app" or just "Print
Spooler"
3. Force quit this process

If this solves it, then it seems to be a regression in the new LC dp

builds.

Thank you Mark!

I'm sure like most folks that sell software, we have a small camp of 
customers that always want to be on the leading-edge and, whether its a 
new macOS or a new Windows OS (or OS feature), we get contacted early 
and often about whether our software will be compatible.


There are some days I just want to scream "It will work when it will 
work!" but I do understand their interest in new technologies and so we 
try to provide some reasonable answer. These responses (from you and

I can't really say when we will add a native ARM64 build for Windows - 
it will depend largely on demand and need.


That being said, we have recently updated how we build the windows 
engine to use the most recent version of Visual Studio (which has 
arm64 target compilers) so that is at least a step in the right 
direction.


I know, this is probably way ahead of any practical answer, but I 
know we WILL have customers asking us if our app (built on LC9.6.11) 
will run on Windows on ARM on day one.


Windows ARM has been available to everyone for a while - albeit not 
strictly a 'public' thing, virtualization tools like VMware on macOS 
will download and install the ARM version of windows automatically if 
you are running on an ARM mac.


We have a couple of people internally who have ARM macs, and use 
VMware to run Windows in ARM and we haven't seen any problems.


So I can echo what Mike said - especially since Microsoft added x86-64

2) about a year or so ago - both x86 and x86-64 versions of the 
LiveCode engine run seamlessly on it.


Another thing to remember is that Microsoft are not forcing a 
processor transition unlike Apple have done twice now (in the last two 
decades) - I fully expect that Windows on ARM will support Intel 
executables indefinitely, just like x86-64 Windows continues to 
support x86 executables.


Warmest Regards,

Mark.

Re: Revisiting Lock Screen

[Paul Dupuis via use-livecode]

In our app, we have a lot of handlers (internal APIs) that get called by 
other handlers and, as multiple developers are involved, knowing what is 
calling what takes some effort. To address the issue of screen locks, we 
adopted a coding standard as follows:


If a handler should lock the screen, we add the following code:


put the lockScreen into tPreserveLockScreen
if tPreserveLockScreen is false then lock screen -- if the screen is not 
already locked by any calling handler, then lock the screen, else, the 
screen is already locked by the calling handler


... code of the handler 

if tPreserveLockScreen is false then unlock screen -- if the screen was 
not locked by the calling handler, it was locked by this handler, so 
unlock it, else, expect that the calling handler should unlock it (or 
preserve it as appropriate)



I know this doesn't address the specific issue raised in this thread, 
but I thought this model may be helpful to someone reading this thread.

Dropping file on an LC standalone...

[Paul Dupuis via use-livecode]

My question is what message is triggered when a file is dropped on a 
running LC standdalone on Windows


On Windows, if the APP is started by dropping a file on it, the file 
name is available to any handler in the startup sequence via the $1 
special variable. i.e. IF teh variable $1 contains a file name the app 
was started by someone droping the file on teh app or by double-clicking 
a file associated with teh app.


On macOS, this is all handled by appleEvents. i.e. if a file is dropped 
on a LC standalone on macOS that standalone gets an appleEvent message 
and the parameters of the message can be used to get the file name . 
This is true on startup (if a file was dropped on the app to start it or 
an associated file was double clicked to start the app OR on macOS if 
the app is already running and a file is dropped on its icon, the app 
gets an appleEvent message.


So, what message does a LC standalone app on Windows get, if it has been 
running and a file is dropped on its icon? An what is the message path 
of that message (i.e. is it send to the current card, current stack, the 
mainstack card, or the mainstack stack?)


Thanks in advance!

Re: PDF widget print quality

[Paul Dupuis via use-livecode]

I'm not sure it is possible. Livecode's printing tends to be card based 
and at card resolution, typically 72 dpi.


I recall seeing some efforts on the lists and forums to make an object 4 
times bigger (75 dpi x 4 = 300 dpi) so that when it is printed to a 
300dpi printer is is a higher resolution but normal size but I don't 
recall how successful any of those efforts were.


There is probably an ancient enhancement  request in the Livecode 
Quality Center to support higher-resolution printing.

This prints a full page at the proper size, but not with acceptable print

Re: polygrid formatted column width

[Paul Dupuis via use-livecode]

You have the dataWidth of the polygrid for the formattedWidth of the 
widget (to be wide enough to display all data), but what I think you 
want is some equivalent of the fomattedWidth of each column. I don't 
believe any such property exists in the polygrid. It would be like 
setting the columnWidth of a column to 'auto' or something like that, 
which would be a nice feature enhancement, but doesn't exists currently. 
You're welcome to file a feature enhancement. I'd definitely +1 it.


You would have to roll your own, probably using the 
"measureText(text,objectReference,[mode])" function. You would need to 
iterate through all the rows of data and find the longest string (in px) 
for each column via measureText and then set the columnWidths of the 
polygrid to that set of column widths. I am also not sure if measureText 
can use a widget as an object reference, so, if not, you may need a 
hidden field/button as teh object reference set to the same font and 
size as the polygrid.


Anyway, that's how I would try to solve this :-)

Re: Manipulating PDF's

If you just need a person to view a particular spot in a PDF, using the 
PDF widget in Livecode would be easier than trying to manipulate an 
arbitrary PDF viewer. If there is a way to adjust the scroll, it is 
probably PDF viewer specific and you'd need to know whether the user is 
using Apple Preview (macOS only) or Adobe Reader or Foxit Reader, or 
something else as their PDF viewer.

on cellClick pColumnNumber,pRowNumber, pCellRect
-> ERROR: pColumnNumer is not a number (if I remember correctly)

Noone clicked anything I just set the pgData :-/

And also wrecked the order of its correctly prepared (in the array) content.
Big fun! :-/

Anyone else experienced something like this?

AW: Re: macOS window maximization weirdness

[Paul Dupuis via use-livecode]

So, I finally tracked this maximization weirdness down.

This only occurs on macOS when a window is maximized using the titlebar 
maximization icon (which cause teh window to go to fullscreen, hiding 
the window titlebar and macOS menubar. The menubar and titlebar 
re-appear if your roll the mouse over where they are hidden, allowing 
the user to click on titlebar maximization icon to restore the window to 
normal size.


The issue also only occurs if the resizeStack handler for the window 
uses the passed parameters to determine position of objects within the 
window. i.e. if you do:

Example 1)
on resizeStack pNewWidth, pNewHeight
  set the bottomRight of btn "X" to (pNewWidth-5),(pNewHeight-5)
end resizeStack

There can be a problem under the specific circumstances below. Where as:
Example 2)
on resizeStack
  put the width of this stack into pNewWidth
  put the height of this stack into pNewHeight
  set the bottomRight of btn "X" to (pNewWidth-5),(pNewHeight-5)
end resizeStack

Will work under the specific circumstances below.

When a window is mazimized on macOS, that window is sent a resizeStack 
message with the correct parameters, so either code block above works.


However, on macOS ONLY (not Windows) when a window is maximized, after 
the resizeStack message is sent, a desktopChanged message is also sent


My problem was that I also have a on desktopChanged handler in my app. I 
had expected desktopChanged to only be sent when a monitor is added or 
removed or the resolution of a monitor is changed (increased or 
decreased), not if a window is maximized.


My desktopChanged handler, at one point, executes either a:

  set the effective width of window tWindow to tMontiorWidth
OR a
  set the effective height of window tWindow to tMonitorHeight

Either of which sends a resizeStack message to the stack/window. 
However, when it is sent this 2nd time as a result of the window 
maximization (which does a successful resizeStack, then desktopChanged, 
which sets teh effecting width/height, that causes a resizeStack) the 
resizeStack parameters, pNewWidth and pNewHeight are EMPTY, so any 
placement of controls based on the parameters use empty, which gets 
treated as zero.


The work-around is the do Example 2 for resizeStack, but I think is 
might be considered an ENGINE BUG that on macOS, not Windows, 
maximization sends a resizeStack and then a desktopChanged message. No 
monitor has been added or removed, nor has the resolution of any monitor 
been changed, therefore I don't think a desktopChanged message SHOULD be 
sent on macOS window maximization. I think this is a bug?


Does anyone have a valid reason why macOS should receive a 
desktopChanged message on window maximization when Windows does not?

I have a standalone, built with Livecode 9.6.11 STABLE, where for some

It is not every resizable window (stack) in my app, just some. It is 
not every version of macOS, just some. For example, on macOS Sonoma, 
the offending windows (again, a subset of all my app's resizable 
windows) work fine. On Mojave, they do not.


On Windows, they all work fine when maximized (meaning they are all 
rendered as expected). On macOS and Windows, they all RESIZE (i.e. 
user window resizing) correctly. It is only certain windows AND only 
on certain versions of macOS, and only when maximized (using the 
titlebar green maximize circular icon). In fact. you can RESIZE the 
window manually on macOS Sonoma or Mojave up to the working area of 
the screen (all so the full screen except the menubar) and they all 
render correctly. It is just the "full screen" maximize Apple now does 
where it hides the window's titlebar until you hover over where it 
would be that have a problem and, again, just for certain windows on 
certain versions of macOS.


I'm baffled as the resizeStack handlers are the same across platforms 
(macOS and Windows). There is NOT platform specific code in the 
resizeStack handlers and, I believe, that when a window is maximized, 
Livecode just sends a resizeStack message.


Has anyone seen or heard of any weirdness like this?

I do not have a whole set of macOS version to test on. Sonoma and 
Mojave are about it. I can compare the resizeStack handlers for the 
stacks that maximize correctly with those that don't to see if there 
is some issue, but they all work correctly on Windows and work 
correctly when manually resized.

Re: Mousedown in Application Menubar Messages

I've not experienced any problems with the menubar group receiving a

A long time back, I did have an unnecessary  'wait 0 with messages' in

my mouseDown handler was done (or so it seemed).

Re: macOS window maximization weirdness

[Paul Dupuis via use-livecode]

It may be that. I have to figure out a work-around. I will keep 
properties in mind as I dig into the resizeStack handlers.


And yet, I shouldn't have to figure out a work-around. Since it works on 
Sonoma and Windows 11, it really SHOULD work on Mojave (and Monterey and 
all supported versions of macOS).

 My guess is that it is a timing issue and you are using a property 
value that isn’t yet updated.  That is probably (hopefully) going to 
be a good place to start since you have good and bad placement in the 
same handler.

Below are screen shots (full desktop) of each window maximized on 
Windows 11 (correctly), Sonoma (correctly) and Mojave (incorrectly 
drawn). Again, there windows, on ALL 3 OS versions, can be manually 
resized without problems. It is only when you click on the macOS 
Maximize icon in the title bar. In addition to not drawing correctly on 
Mojave, we also witnessed them not drawing correctly on Monterey. The 
resizeStack handlers have NO platform specific code.

Logically, there must be some difference in the resizeStack handlers. I 
have already received the suggested to try having resizeStack send a 
"doResize" (or some handler name) message in time that does the actual 
resize as a work-around. I have not had a chance to try that yet. I 
expect I may OR may not fine that perhaps some use the width and height 
passed as resizeStack message handler parameters while others get the 
width and height of the card. I'll see if there is some commonality on 
how the resizeStack is getting the dimension to resize to between those 
windows that work and those that don't.


However, logically, it certainly seems like there is some OS version 
specific engine bug emerging here since the same code works on Windows 
and some versions of macOS and not others versions of macOS.

When drawn incorrectly, are controls the wrong sizes/rects?
Or content/visual glitches? Of what nature?

Thought it might be worth following up, in case anyone saw similar -
or might jog my own memory! So many LC/OS issues, details help

Re: Bug 23507 - LC Clipboard Polling Failure

[Paul Dupuis via use-livecode]

Ralph,

Thanks for the tip. As I did into this problem, I'll give that a try.

I'm just getting tired of Apple and/or Livecode changing things so that 
code that DID work is then discovered NOT working any more.


I have very limited time and resources and I'd like to spend MORE of it 
making new features for my products that fixing bugs that happen because 
a new macOS (or Windows) came out or a new version of Livecode or some 
combination breaks what was working.


I always post on this list first in hopes someone else has see whatever 
issue I have run into and can say definitively look at this bug number 
in the LC Quality Center for both the issue and, ideally, a work-around.

macOS window maximization weirdness

[Paul Dupuis via use-livecode]

I have a standalone, built with Livecode 9.6.11 STABLE, where for some 
windows (stacks) on certain macOS versions, maximizing the window 
results in no controls being drawn or most controls being drawn incorrectly.


It is not every resizable window (stack) in my app, just some. It is not 
every version of macOS, just some. For example, on macOS Sonoma, the 
offending windows (again, a subset of all my app's resizable windows) 
work fine. On Mojave, they do not.


On Windows, they all work fine when maximized (meaning they are all 
rendered as expected). On macOS and Windows, they all RESIZE (i.e. user 
window resizing) correctly. It is only certain windows AND only on 
certain versions of macOS, and only when maximized (using the titlebar 
green maximize circular icon). In fact. you can RESIZE the window 
manually on macOS Sonoma or Mojave up to the working area of the screen 
(all so the full screen except the menubar) and they all render 
correctly. It is just the "full screen" maximize Apple now does where it 
hides the window's titlebar until you hover over where it would be that 
have a problem and, again, just for certain windows on certain versions 
of macOS.


I'm baffled as the resizeStack handlers are the same across platforms 
(macOS and Windows). There is NOT platform specific code in the 
resizeStack handlers and, I believe, that when a window is maximized, 
Livecode just sends a resizeStack message.


Has anyone seen or heard of any weirdness like this?

I do not have a whole set of macOS version to test on. Sonoma and Mojave 
are about it. I can compare the resizeStack handlers for the stacks that 
maximize correctly with those that don't to see if there is some issue, 
but they all work correctly on Windows and work correctly when manually 
resized.

Re: Message Sent when Resizing Widgets: Workaround

[Paul Dupuis via use-livecode]

Bob,

This is nice trick (and code) to use an overlayed button to get a widget 
to respond to standard messages. Impressive!


I really think that Livecode Ltd. needs to prioritize adding a set of 
"standard" object messages to every current widget to address these 3 
bugs (and their generalization to all other widgets):

https://quality.livecode.com/show_bug.cgi?id=24458
https://quality.livecode.com/show_bug.cgi?id=24437
https://quality.livecode.com/show_bug.cgi?id=24429

Every widget should be able to handle OR pass  through (just like every 
Livecode field, button, scrollbar, etc.) resizeControl, mouseEnter, 
mouseWithin, mouseLeave, mouseDown, mouseDoubleDown, mouseStillDown, 
mouseUp, mouseDoubleUp, and probably a bunch more.



On 12/29/2023 5:39 PM, Bob Sneidar via use-livecode wrote:

I have a kind of custom group composed of a segmented widget and a transparent 
button the exact size of the widget, the purpose of which is to be able to 
handle messages that are otherwise not sent to the widget. In fact almost NO 
messages are sent to a widget, a source of some consternation from users of 
this list.

There are three issues with this, the first being that if there is a button on 
top of a widget, then no messages get sent directly from the engine to the 
widget at all! The second is that if I add more segments or resize the widget, 
the width of the overlay button also needs to match. The third issue is that if 
I click on the overlay button, I need to know, as in the case of a mouse click 
which segment was clicked on.

To this end I wrote some handlers for the widget and the overlay button which 
allow you to handle any messages a button might receive and then process them 
for the widget. This is of course just a basic framework. The important 
handlers are resizeControl and the getProp clickedTab.

Unfortunately, and although changing the size of the widget will send the 
resizeContol message to t he widget, editing the width in the widget’s 
properties palette does NOT send the message. The upshot is that if you make 
changes to a widget, you can simply run the resizeControl handler to clean 
things up.

In my case I always want the widget segments to be the same size, and I always 
want the widget to be centered on the card. YMMV. You could get even fancier if 
you wanted and calculate the formattedWidth of the segment names, add a little 
air around them, then set the width of the widget to the sum of those, and then 
the minimum segment widths to those formattedWidths. But manipulating the 
minimum segment widths to get the correct width for each segment is something I 
have not fathomed. I wish they had given us a property for the *actual* segment 
widths.

For the widget itself I have these handlers:

on hiliteChanged
put the hilitedItemNames of me into tTabName
put the itemNames of me into tTabList
tabChanged tTabName, tTabList
end hiliteChanged

on tabChanged pTab, pTabList
-- your code here
end tabChanged

on resizeControl
wait until the mouse is up with messages
put the long id of me into tMyID
put wordOffset("card", tMyID) +1 into tPos
put word tPos to -1 of tMyID into tParentCard
put the width of widget "TabBar" into tWidth
put tWidth / the itemCount of widget "TabBar" into tSegmentWidth

repeat with i = 1 to the itemCount of widget "TabBar"

   put tSegmentWidth into item i of tSegmentWidths
end repeat

set the itemMinExtents of widget "TabBar" to tSegmentWidths

-- center the widget left to right

put the loc of widget "TabBar" into tTabLoc
put the loc of tParentCard into tCardLoc
put item 1 of tCardLoc into item 1 of tTabLoc
set the loc of widget "TabBar" to tTabLoc

-- set the rect of the overlay button to match

set the rect of button "btnTabOverlay" to the rect of widget "TabBar"
end resizeControl


Then for the overlay button:

on mouseUp
put the clickedTab of me into tTab
set the hilitedItemNames of widget "TabBar" to tTab
end mouseUp

on mouseDoubleUp
put the clickedTab of me into tTab

-- your code here

end mouseDoubleUp

getProp clickedTab
put the clickLoc into tClickLoc
put the itemNames of widget "TabBar" into tTabNames
put the rect of widget "TabBar" into tTabRect
put item 3 of tTabRect - item 1 of tTabRect into tTabWidth
put the itemCount of widget "TabBar" into tTabCount
put tTabWidth / tTabCount into tSegmentWidth

repeat with i = 1 to tTabCount

   put round(item 1 of tTabRect + (tSegmentWidth * i)) into tSegmentBounds
   
   if item 1 of tClickLoc <= tSegmentBounds then

  put item i of tTabNames into tTab
  exit repeat
   end if
end repeat

put the itemMinExtents of widget "TabBar" into tExtents

return tTab
end clickedTab

Anyone know?


Fetching a value directly from a variable will always be faster than 
any other method - as it essentially reduces to fetching or storing a 
value from a (integer indexed) table.


In contrast, fetching a custom property will require a message send 
unless lock messages is set, and then an array lookup (to actually get 
the property's value).


Custom property sets are stored using the same data structure 
internally as livecode arrays so getting `the cMyArray of me` 
eventually reduces to the same as 
objectsCurrentPropertySet["cMyArray"] - the latter lookup is more work 
than just fetching a value from an internal table.


UPSHOT:

Fetching a value directly from a variable is a constant time operation.

If lock messages is false, then the time it takes to fetch a custom 
property value will be somewhat proportional to the length of the 
message path from the point of view of the object you are accessing - 
i.e. how many frontscripts, backscripts, stacks in use, and parent 
objects/behaviors the object has.


If lock messages is true, then the time it takes to fetch a custom 
property value will be pretty much the same as doing an LC array key 
lookup.


Now whether or not this actually matters in any one case will largely 
depend on how often such access is being done - if its a few times in 
the context of UI-related code then it probably won't be appreciable; 
if, however, you are fetching a custom property 10's of times in a 
tight loop and the rest of the loop is only doing small amounts of 
work, you'll definitely notice a difference.


SIMPLE BENCHMARK:

```

on mouseUp
local sMyArray

on mouseUp
   set the cMyArray of me to [ 1, 2, 3 ]
   put empty

   local tTime
   put the milliseconds into tTime
   repeat 100 times
  get the cMyArray of me
   end repeat
   put "CUSTOM PROP:" && the milliseconds - tTime & return after msg

   put the milliseconds into tTime
   lock messages
   repeat 100 times
  get the cMyArray of me
   end repeat
   unlock messages
   put "CUSTOM PROP (LOCKED OUTSIDE):" && the milliseconds - tTime & 
return after msg


   put the milliseconds into tTime
   repeat 100 times
  lock messages
  get the cMyArray of me
  unlock messages
   end repeat
   put "CUSTOM PROP (LOCKED INSIDE):" && the milliseconds - tTime & 
return after msg


   local tMyProps
   put [ 1, 2, 3 ] into tMyProps["cMyArray"]
   put the milliseconds into tTime
   repeat 100 times
  get sMyArray["cMyArray"]
   end repeat
   put "ARRAY ELEMENT:" && the milliseconds - tTime & return after msg

   put the milliseconds into tTime
   lock messages
   repeat 100 times
  get sMyArray
   end repeat
   unlock messages
   put "SCRIPT LOCAL:" && the milliseconds - tTime & return after msg
end mouseUp
end mouseUp
```

RESULTS (1 million iterations):

CUSTOM PROP: 2006
CUSTOM PROP (LOCKED OUTSIDE): 116
CUSTOM PROP (LOCKED INSIDE): 125
ARRAY ELEMENT: 80
SCRIPT LOCAL: 38

ANALYSIS:

The above results are run in the IDE which is important to mention 
because the message path in the IDE is typically longer than that in 
standalones (as the all extension libraries are loaded, and the IDE 
inserts its own front/back/stacks into the message path).


Accessing custom properties with messages locked is nearly 10x faster 
than without (again that multiplier will be vary with the length of 
the message path).


Using lock/unlock messages for every custom property access has a 
(quite negligible) 10% overhead - and the message path overhead (in 
the IDE) is about 40% of the total (the array element fetch will be 
the rest).


Accessing a script local is
  - about 50x faster than accessing a custom property when messages 
are sent
  - about 3x faster than accessing a custom property when messages are 
not sent

  - about 2x faster than accessing an array element

Just to reiterate - these figures are for 1,000,000 accesses done in a 
tight loop (in the IDE). If you do it for (say) 1000 iterations then 
the differences are within the margin of error of measuring a 
millisecond.


Overall, my suggestion would be probably to do a combination of both -

Re: Get rid of the remote debugger

[Paul Dupuis via use-livecode]

For what it's worth, I sometime get these errors. I develop on Windows 
11 (x64) using LC 9.6.11 and do not develop for mobile or web, so no 
remote debugging. I do not want to get rid of (remove) or turn off 
script debugging. I use the script debugger all the time.


There is some recipe, that I have not figured out yet, where this error 
occurs, when you are just doing what I'd consider "normal" debugging. I 
just have not had time to pin it down. (To busy filing PDF Widget bugs 
and enhancements to get it to parity with the XPDF external).

Ah! I am pretty sure it can be done, but I do not know how to do it 
exactly. By guess is that you will probably need to edit the row 
template to add a "grey" background behind the columns your may want to 
grey and then for those columns in the Property inspector, create a 
custom column behavior to show or hide that grey background graphic 
based on whatever calculation your want.


That is a guess though.

Usually, you do not disable or grey-out columns in a Datagrid, but make 
them invisible (hide or show the column) if they are not applicable to 
some view you want.

Except, the "PowerButton" widget actually receives "resizeControl" just 
as a group does when its rect is changed by script control (as well as 
by user manipulation of its resize handles). So it *is* inconsistent. 
Or, at the very least, poorly documented.


And, for my purposes, if the PowerButton can received a resizeControl 
handler, I'd really like to see the PDF widget get the message also. The 
XPDF external requires, as its target for a drawing area, a Graphic 
inside a Group, and the containing group gets resizeControl. You can use 
that resizeControl to show/hide scrollbars as appropriate based on zoom; 
set the scroll to keep a highlighted part of the PDF in view when 
resized; and more. For a migration path from the XPDF External to the 
PDF Widget, the PDF Widget should support resizeControl as well.

Re: resizeControl wishes...

[Paul Dupuis via use-livecode]

Thank you Richard.

I see what the issue for me was. Groups do indeed receive a 
resizeControl message automatically if the rect is changed by script. 
However, the message (resizeControl) use seems inconsistent. For 
example, while a group does received the resizeControl message, a field 
does not seem to. Also, what I specifically ran into was that the PDF 
Widget does not received a resizeControl handler (and it would be really 
useful if it did!)


I'll submit an enhancement request (below) for adding resizeControl to 
the PDF Widget (assuming it's possible), but I don't have the time to 
determine what widgets support resizeControl and which don't and what LC 
objects (other than groups) support resizeControl and which don't.

resizeControl wishes...

[Paul Dupuis via use-livecode]

resizeControl is sent "only sent when the user resizes a control by 
dragging its handles. It is not sent if a handler changes the size of a 
control by changing its properties (width, height, and so on)."


Does anyone else really really wish that resizeControl was set when the 
control's size is changed via script? I sure do!


For example, I have cards with multiple groups of objects on them. Each 
of my groups (and sometimes sub-groups) have resizeControl handlers that 
position everything in the groups appropriately. I do this for 
portability. If I copy the group to somewhere else, the handler 
(resizeControl) that knows how everything is to be moved and resized 
goes with the copied group.


My card script has a "resizeStack" handler that just sets the rects of 
the top level groups and dispatches resizeControl to each group on the 
card after changing its rect. I really wish I could eliminate these 
"dispatch" (or send) commands. I forget to include them some times, 
simple expecting (even though I know better) that if I change the size 
(rect) of a control with a "resizeControl" handler, that that 
resizeControl handler should execute!


Anyone else wish that resizeControl would get executed if a control's 
size is changed by script? It just seems counter-intuitive that it does not.

Hi friends,

before I post an enhancment request to the "Qualtiy Center", I wanted to hear 
your opinions about this.

Wouldn't it be great if ALL widgets would receive and handle at least a mouseup 
(and mousedown) meassage?
I have always wondered why that is not the case.

This way scripting would be a lot easier for us and we do not have to remember 
the many different messages
the widgets have. Yes, they can be seen in the script editor on the left side, 
nevertheless... :-)

Examples:
PolyGrid -> cellclick
PolyList -> itemclick
Segmentedcontrol -> hilitechanged
Switch Button -> hilitechanged
Radial Slider -> valueChanged
Navigation Bar -> hilitechanged
Line Graph -> receives NO message at all?



It seems to me that for most of these (not sure about Line Graph) that 
'selectionChanged' is the more applicable 'standard' message than a 
mouseUp or mouseDown, although I would wholly agree that every (or 
nearly every) widget should pass mouseUp and mouseDown if they do not.

What to set the clipboardData to for exchanging styled text with a 3rd party app

[Paul Dupuis via use-livecode]

Hivemind,

Recommendation as to what is best to set the clipboardData property to, 
when you want to copy styled text from a field to the clipboard for 
exchange with a 3rd party (any 3rd party) application that supports some 
form of styled text, that can include text in multiple languages (i.e. 
Unicode)?


Examples:
1) set the clipboardData["rtf"] to the rtfText of fld "X"
2) set the clipboardData["html"] to the htmlText of fld "X"
3) set the clipboardData["text"] to the text of fld "X" -- since the 
text in field since LC7 is unicode

4) set the clipboardData["unicode"] to the textEncode(fld "X","UTF-16")

Something else? Should fullClipboardData or rawClipboardData be used 
instead? Looking for best practice recommendation.

Paul Dupuis wrote:

As others have pointed out, resizeStack is sent. And by definition, wouldn't 
the windowBoundingRect be the maximized size?


So, the windowBoundingRect actually only applies to the main monitor 
(where 'the screen of stack "X" = 1' so you actually need to consider 
windowBoundingRect deprecated and use the working screenRects or the 
effective working screenRects (I may have my adjectives in the wrong 
order!) and compare the screen of the stack in question to the line in 
the returned screenRects for a bounding rect equivalent.



I'm curious: what does the app need to do differently if the user resized the 
window to that rect manually vs the Maximize button?


It is an oddity (bug) where certain windows in HyperRESEARCH are not 
redrawing their contents properly when the maximize icon in the title 
bar is clicked and the window maximized. However, if you resize the 
window to the maximum size, everything is redrawn correctly. I was 
asking about the maximize message as it may have aided in debugging the 
issue - if there was such a message sent. This is also only on macOS. 
The same windows maximize correctly whether resized manually or the 
maximize icon in the title bar is clicked. Also, I have not determined 
if this behavior started happening on some specific version of macOS yet.


In theory, as you stated, there should be no difference between resizing 
a stack/window manually and clicking the maximize icon.

Re: Property Inspector bug for keys with commas in the key name

[Paul Dupuis via use-livecode]

Hi Bernd,

You do make a good point about the documentation regarding custom 
properties. Assuming people read the documentation. At the same time, 
you used to be able to use commas in custom property names. As Curry 
noted, Livecode even used to use them in the standalone setting 
properties, so the mothership set a precedence.


My problem is that I have stacks where commas were used because they 
could be used and there was value to using them as evidenced by how 
Livecode used them in the standalone settings. Now I can only edit them 
via scripts rather than the current PI.


It's not really a problem since I can do updates by script. It is more 
of just an annoyance.


Knowing that the current issue if the hilitedElement of the tree view 
object, I won't bother trying to look for any quick fix I could make to 
the PI code in the IDE. Thanks for the information.



On 11/3/2023 2:29 PM, Niggemann, Bernd via use-livecode wrote:

Hi Paul,

The problem with the comma in a customproperty name in the Properties Inspector (PI) arises because 
the PI uses a treeview to display the customproperties. More specifically the 
"hilitedElement" to retrieve the current selection and "hilitedElement" has the 
form:
"A comma delimited list of array keys."

Now you have a comma in your customproperty name and at that point the PI is 
confused as to what is the key and what is the value and fails to display both.

However I wonder if treeview or PI is to blame:

Page 145 of "Livecode User Guide" 9.6.10
Custom Property Names
The name of a custom property must consist of a single word and may contain any 
combination of letters, digits, and underscores (_). The first character must 
be either a letter or an underscore.

Page 113 of "Revolution User Guide 2.0" printed edition from 2004
Custom Property Names
The name of a custom property must consist of a single word and may contain any 
combination of letters, digits, and underscores (_). The first character must 
be either a letter or an underscore.

So I am afraid that treeview could not expect a comma in a customproperty name.

Kind regards

Re: Direct editing of polygrid text cells and polylist text elements

[Paul Dupuis via use-livecode]

+1

I'd like to know this too as I can see no way in the Property Inspector 
or the pgColumns property to indicate a column is 'editable'. Nor can I 
find any property, message, etc. in the polygrid Dictionary entry that 
seems to suggest cell editing.

I have one question which doesn’t seem to be addressed in the documentation. 
The polygrid widget specifications say that it supports “direct cell editing” 
but I am not able to find any way to do this. Has anyone found a way?

More generally, do we have any multi-line input field options for Livecode 
which render well across all platforms? Polygrid and polylist work beautifully 
in displaying already existing data from some sort of data repository ... but 
it would be awesome to provide the ability for users to input information as 
well as display it using the brilliant polygrid and polylist tools.

Providing truly cross-platform inputting of data and information in an easy way 
would provide the final puzzle piece for many of us wanting to provide a modern 
and beautiful user interface for our apps.

Many thanks 😊

Re: Oddity in 'currentCard' function?

FYI - this is exactly what we use currentCard for in our application - 
change the card that will be displayed when a user shows/opens a stack 
to match a change in user data when the stack is not actually open yet.

Okay, I get that  id  is a legacy return value when 
there is no name.


I'd just like to confirm that:

this card of stack "X"

the currentCard of stack "X"

refer to the same card, even if in different ways (actual object 
reference vs short name)?


If so, I will switch to using "this card of stack". I had thought that 
the 'this card' was always the card in the object hierarchy of the 
object the script was running in and had forgotten that you could say 
'this card of stack ...' to reference the active card in another stack.

Oddity in 'currentCard' function?

[Paul Dupuis via use-livecode]

I think I found a oddity in the "currentCard" property.

The documentation states that the currentCard property return the short 
name of the current card of a stack:


for example: put the currentCard of stack "Untitled 1" into tCardName

You can then execute code such as: set the myProperty of cd tCardName of 
stack "Untitled 1" to tValue


However, if the card does not have a name set, then current card returns 
"card id ", example: card id 1002 and the above 2 lines of 
code return a runtime error of 'can't find card'


put the currentCard of stack "Untitled 1" into tCardName
set the myProperty of cd tCardName of stack "Untitled 1" to tValue

WORKS for cards with a name
FAILS for cards without a name (where currentCard returns 'card id I think currentCard should just return 'id 1002' rather than 'card id 
1002' if a card has no name.


Trying to execute: set the myProperty of cd tCardName of stack "Untitled 
1" to tValue WHEN tCardName contain 'card id 1002' produces a run time error


But trying to execute: set the myProperty of cd id 1002 of stack 
"Untitled 1" to tValue works.


Oddly, set the myProperty of cd tCardName of stack "Untitled 1" to 
tValue FAILS if tCardName contains "id 10001" (and yes that card with 
that ID exists)


Oddly again, set the myProperty of the currentCard of stack "Untitled 1" 
to tValue DOES WORK whether they have a name or not


But again, breaking that example above (set the myProperty of the 
currentCard of stack "Untitled 1" to tValue) into 2 lines:

put the currentCard of stack "Untitled 1" into tCardName
set the myProperty of cd tCardName of stack "Untitled 1" to tValue
FAILS if the card has no name.

Something just seems off here?

When I try on Windows 11 using Livecode 9.6.10 a rawKeyDown or rawkeyUp

I think this is a bug of some sort that should be reported to the

The keyDown or keyUp message does not get sent. the OS (Win11) 
apparently intercepts and raises/lowers/mutes the volume or play/pause 
as applicable.

Volume and Media Keys: In the HID standard, volume and media control keys
often have specific usage IDs. For example:


- 0xE9 is for volume up.
- 0xEA is for volume down.
- 0xE2 is for mute.
- 0xCD is for play/pauseetc

Re: OS X document icon missing

[Paul Dupuis via use-livecode]

Yes, that look right. The file extension is .rbox and the file type is 
'rbox' for 'Recipe Box Files'


I wonder since it only READS .rbox files and does not create them, if 
you need to context-click (CTRL-CLICK) on a .rbox file and select "Open 
With.." to see if your app (an reader of .rbox files) is in the list and 
open one to get macOS to associate viewing .rbox files with your App, 
since it does not actually create .rbox files?

No go. Here is the relevant part of the plist:

    CFBundleTypeExtensions
    
.rbox
    
    CFBundleTypeIconFile
    StandaloneDoc.icns

The app does not create new files, it just opens the existing stack, 
originally a LC file. I tried a "save as..." but that didn't work 
either. Is there a way to set the signature on an existing file? I did 
try and the stack wouldn't open, presumably it's corrupted.

I don't think this is related to the problem (above) you have. If you 
have identified the document extension in the Standalone setting for 
macOS and set an ics file of icons (or the appropriate sizes required by 
Apple) than documents created by that app should display the icon. I'd 
double check that the Docunmet extension and Document Type (if you're 
using Types) in the setting match what the file is actually using. I've 
had an extra character (sometime a space which is hard to see) in the 
past that took me a bit to figure it out.


Unrelated, if you ever need more than one document type, below is some

Another macOS Codesigning/Notarization issue

[Paul Dupuis via use-livecode]

Help,

I am trying to switch Notarization tools for the Apple November 
deadline. I was using macOS Mojave with Xcode 10.2.1 and not (to use the 
new mandated Notary tool) have to move to Sonoma with Xcode 15.0.0.


I have signed, notarized, and stapled (all responses returned were what 
the lessons at Livecode.com by Matthias said they should be) a Livecode 
9.6.10 Standalone using my Mojave system (the old tool) and it works on 
Sonoma and Mojave


I have signed, notarized, and stapled (all responses were as the lesson 
said they should be) a Livecode 9.6.10 Standalone using my Sonoma system 
(the new tool) and I get  an error trying to run it on Sonoma. It runs 
under Mojave (although the first time the cursor spins a lot and it 
takes a while to start)


The error is an extraordinary helpful dialog with a smiling macOS icon 
that say 'The application "" can't be opened." and an OK button.


I though for a bit that it was that I was still building for Intel and 
the Sonoma is a M1 macBook Air, so I changed the Standalone settings and 
redid everything (again all seemed okay) and the GetInfo says Universal 
(where it said Intel before) but I get the same message.


AGAIN, the old Notarization procedure produces an notarized (and 
stapled) app (that is actually just Intel) that runs without error on 
Sonoma on M1 MacBook Air and Mojave on Intel Powerbook, but the new one, 
from the lessons for Xcode 13+ produced the error above and my app will 
not run.


Security is set to allow App Store and Identified Developers.

Unless I figure this out, I will not be able to make new version of our 
macOS app after November 1. Has anyone else experienced this? Has any 
one see this message?

So for some time, I have only downloaded the "command Line Tools for

The above is the first reason I have seen, if you are only developing

If you download from the Apple Developer site, apparently only the 
public key part of teh cert is downloaded. The private key, created on 
the machine you did a Code SIgning Request on is on that machine and not 
the Apple Developer site, which is why you need to either export and 
import between macs or generate a new certificate.

Re: Deployment: a plea/opportunity

[Paul Dupuis via use-livecode]

I'd love to see versions of Livecode stacks that assist with code 
signing and notarization for as many platforms as possible (I am aware 
of stacks for Windows and macOS) built into Livecode.


That said, for my two major problems (1 on macOS and 1 on Windows), I 
don't think there is anything Livecode could have done to help (other 
than lessons/documentation).


On Windows my current certificate - a .pfx format code signing cert - is 
expiring in November, so I renewed it. However, as of June 1 2023, the 
Windows code signing industry moved to requiring all code signing 
certificates to be issued on an encrypted USB token and you must use 
specialized software (that 3rd party can not hook into to prevent 
malware) to access those tokens to code sign.


On macOS, I needed to update code signing and NOTARIZATION to 
accommodate that Apple is switching to a new notary tool that only rns 
on new versions of macOS (I was using Mojave and atool) so I HAD (forced 
by Apple) for update to using the macBook Air I have that happened to 
have Sonoma on it and than meant Xcode 15 command line tools for the new 
Notary tool. atool stops being accepted by Apple some time in November 
so my old notarization steps will stop working. The change in notary 
tool was easy with Matthias's lessons and documentation on livecode.com. 
The problem was getting my Apple code signing certificates AND related 
certificates on to the MacBook air from the Apple Developer site, 
something I don't think Livecode can really help with.


Yes, others have had still other issues some of which improvements in 
Livecode might help address, but for the two I ran into that I turned to 
the list for help for, they were ultimately nothing that I think 
Livecode could help with.


Just my 2 cents on my 2 issues.

Thank you Panos.  If you or Matthias ever come across (or write) a goo 
step by step for getting Apple Certs to a new machine (new cert from 
Apple to a new machine, existing cert from Apple to a new machine, 
existing cert from one machine to another I think are the 3 
possibilities) you should link to it or add it to the code signing and 
notarization lesson.


We only do this rarely. For example I have a Apple Code signing cert 
that was created in 2021 and good until 2026. That was a replacement for 
an earlier one. I put than on a Mojave system that I have used to code 
sign since 2021. In 2 years time I have not touch the certs and would 
not have until 2026 if Apple did change the notarization command and 
make me move to a newer macOS. So I forget how its done. I even forget 
where I filed my own documentation on how to do it. So it's like trying 
to do it from scratch each time.


I try to do all the code signing (mac and win) and notarization (mac) by 
command line even though there are GUI tools (Matthias's excellent stack 
and AppWrapper and on and on) so that I at least know the steps in the 
process and id something goes wrong (because the vendor changes 
something) I know what step blew up.


Any way, thank you again.
