Yes. Even the built-in widgets. At least for now, until we get 
commercial locked widgets.

Re: Problem pasting from Livecode to Mac Mail

[Paul Hibbert via use-livecode]

I use a small utility called PopClip, I wouldn’t be without it (although it 
does have some issues with LC on occasions), but it does allow you to choose to 
paste plain text if you wish along with lots of other useful copy/paste 
options. Saves me from some frustration.

It’s available on the App store. More info from pilotmoon.com if that helps.

Only the documented ones.
Even the property inspector shows only the "user_visible" ones.
The only possibility I can see is to scan the lcb file (if it is available).

So, if somebody doesn't document the properties and the widget is not "open 
source" then you get nothing, whether programatically or not.


Might be easier to examine the manifest.xml file for the properties.
At least via a script.

Re: Custom properties of IDE palettes?

But they do. Specifically, stack "revPropertyInspector 1" is not a
script-only stack. It has many objects, and it does have custom properties.
For example, this locks the inspector to its current object:

set the cLocked of stack "revPropertyInspector 1" to true

Re: Custom properties of IDE palettes?

I don't think they have any custom properties... at least, if they do then
they don't do anything. They are script-only stacks & behaviors that
generate the UI; they don't use custom props for their functionality.

Custom properties of IDE palettes?

[Geoff Canyon via use-livecode]

I'm exploring the LC 8 IDE. If I type in the message box:

put the customkeys of the mouseStack

and put the pointer over the message box, I press return and see a list of
custom properties:

cREVIntelligenceObject
cREVLeft
cREVTopLeft
etc

But if I put the pointer over the Tools palette or the Properties palette,
I get nothing. It's not a mouseStack issue; I can put the name of the
mouseStack and get "revPropertyInspector 1". And this doesn't work either:

lock messages;put the customkeys of stack "revPropertyInspector 1"

Any ideas?

You might be able to use the native "busy" indicator on mobile, which 
doesn't interact with the stack content:


mobileBusyIndicatorStart
mobileBusyIndicatorStop

(There's a handler in the mobileControls library in SivaSiva that 
handles this for both desktop and mobile, actually.)

The first line indicates a low-memory condition. The next few lines show 
at least one script error and a missing object. This is all in the 
standalone builder script, so a bug report is in order.

Re: updating text of a mobile app (newbie)

[Andrew Bell via use-livecode]

A goal this year is to get an app (for foreign language learning) on the
Android and iOS stores. To this end, I have begun to re-study LC8's app
building course; LC itself I've been using for decades.

Let's say my original app gets approved. In that app is a datagrid object
list consisting of 10 vocabulary categories, the contents of  which are
read in from a text file in specialFolderPath("documents"). A few months
later, however, I discover more vocabulary categories are needed.

What do I do? Can I somehow "download" a new text file into
specialFolderPath("documents")? Do I have to completely update my app? Or
something else?

In the past what I've done for my desktop Windows standalones is to
download data from my webserver over the internet. But, I imagine mobile
apps must work differently.

Hand holding very much welcome!

--
Nicolas Cueto



This is VERY doable. I have a mobile app that "phones home" on every  
launch to see if there is new data. The app goes and fetches a text  
file from my server that has an integer value of the last time the  
data was updated (the seconds) and if that value is greater than the  
value saved in a local preferences file on the device the app knows it  
needs to run a soft update. A quick revQueryDatabase returns an array  
of data that then gets used as the dgData.


I'm by no means an expert, but have a couple mobile apps created in  
LiveCode doing something like this and would be happy to talk you  
through the hoops and share some best practices I've discovered along  
the way. Feel free to message me off list.

Error while saving standalone 8 & 9

[Paul Richards via use-livecode]

Trying to save as standalone using LC 9.0 DP11, using a stack that had been 
perfectly fine throughout the 8 series.  Attempting to deploy to Android only 
(although similar errors appear trying to deploy to Windows only)

There was an error while saving the standalone application
91,2026,23
77,2026,23
456,2026,23
572,2026,23

(dp11)/Toolset/libraries/revsblibrary.livecodescript"
573,806,1,revSBUpdateDeployParams

I have removed All Widgets that were installed in 8, so the only Widgets 
showing are the stock installed Livecode ones.  Out of desperation, I deleted 
ALL existing cards form the stack so that there was just 1 new blank card (in 
case a card was holding onto a widget) but I still get the same error.  (new 
stacks are all OK )

If I take the original stack and open in LC 8.x  and try to save as Standalone, 
I get an error saying "could not open module file" ?!

I have also tried to add the new Map Widget and save as Android, but I get yet 
another error; "Could not build R.Java"

I appear to be well and truly stuck now, so any help in troubleshooting this 
would be very much appreciated.

Assuming that 'flatten-to-path' means:

"Produce a compound path which, when filled, produces the same result
as filling and/or stroking a sequence of paths and/or shapes."

Then, in full generality, this is really quite complex - particularly
if you want to preserve curves (which is important if you want your
resulting path to scale arbitrarily).

There are two pieces:

  1) A 'thicken' operation which takes a path and stroke properties as
input and produces a path which can be filled to produce the stroke.
(i.e. the 'inside' of the path is the same as the 'inside' of the
stroke of the original path).

  2) A 'union' operation which takes two arbitrary paths and produces
a single path which, when filled, produces the same result as filling
the first path, and then filling and compositing the second path on
top of it. (i.e. the 'inside' of the path is the same as the union of
the 'insides' of the two input paths).


For what its worth, I found that Skia (in principal) has boolean path 
operation support (i.e. the critical union operation!) - 
https://skia.org/dev/present/pathops.


As we also need something along these lines to support the general 
'clipPath' element in SVG, I had a go at implementing a simple shape 
abstraction.


A shape is basically an expressing where the factors are 
paths/ellipses/rectangles/polygons etc. and the operations are:

  - transform
  - fill (turn the shape into non-intersecting regions relative to a 
fill rule)

  - dash
  - thicken (apply stroke attributes to create the thickened lines which 
are filled to form a stroke)

  - union / intersect / difference / xor

So you can do things like:

  union(fill(thicken(... circle ...), fill(thicken(... square ...))

It seemed to work fine on simple unions/intersections of thickened 
squares circles - as long as there was no collinearity / difficult 
intersections. However, when I tried some of the simple feature icons - 
it did not work so well :(


Basically, the version of the path-ops we have in the version of Skia we 
use seem to suffer from some rather unfortunate collinearity / numerical 
issues - of course, updating Skia *might* fix the problem, however it 
seems that quite a bit has changed since we last updated Skia so that is 
not a 'drop-in replacement' type of thing *sigh*.


Warmest Regards,

Mark.

P.S. One thing I do need to try is 'fuzzing' the shapes before applying 
the boolean ops - i.e. adding a tiny random delta, small enough that you 
won't notice when rendered, but large enough that it turns any difficult 
intersections into easier ones.
