I have a simple script that repeats 5000 times, adding to a counter and

less than 4x as long to execute under LC 7 Server as it does under any 
previous version. I'm running 32bit in LC 7, btw.

Is this possibly related to other slowdowns in the desktop versions?


Unless there is a problem specific to the 64 bit engine it seems more 
likely related to some issue with the DreamHost setup. The script that 
Phil provides in his bug report shows similar nearly instantaneous 
execution times for 6.1.2, 6.5.1 and 7.0.0 served from the same (32 bit) 
machine at WebFaction:


 (6.1.2)
 (6.5.1)
 (7.0.0)

I do have a simple test script with a repeat loop and a list sort that 
takes @ 4 times as long to execute with 7.0.0 as it does with earlier 
versions, but Phil's script doesn't show anything like the same problem 
here as it does on his DreamHost server.

Phil,

Your desktop utility shows a difference of about 8 to 10 times using 
your URLs and about 4 times using mine when run under 6.6.2. Opening the 
URLs in a browser continues to show a significant difference, but it's 
hard to quantify. Could you put a timer in the scripts themselves? Also, 
it seems probable from how they display in the utility and the browser 
that the scripts are not quite identical, with the one at 
 not converting 'CR' to '' as does 
(apparently) the other one. However doubtful it might be that this has 
serious impact, it would be best ensure they are identical.

Thank you, Richmond. The Mover standalone ran here and the stack 
successfully compiled and ran as a standalone on my machine. So, I went 
back and see that under Linux standalone settings, 64bit is deselected 
by default and I hadn't even bothered checking (red-face goes here). All 
I did was deselect Windows and OS X... I would like to politely suggest 
if Linux is by default going to build for Windows and OS X, it could 
also build by default for both Linux architectures.


It seems the answer dialog may be a problem in standalone building. 
Opening a standalone that uses an answer dialog returns this error, 
"Error 91,15,1 (linebreak without a comma here in the error message) 
532,52,1 while loading stack: pLibraryName". Clicking "OK" does nothing. 
The dialog has to be dismissed by clicking the close button in the title 
bar. The dialog reappears. Same issue with dismissing/closing it. The 
app window then opens. A button that goes "beep" works as expected. The 
button that displays the answer dialog works and displays the proper 
text but the dialog again cannot by dismissed by clicking "OK".


That's what I have here. Does this happen for you , or anyone else?

list etiquette

[Warren Samples]

Hello all,

From time to time certain issue of list etiquette have been brought up 
and discussed. Cross-posting to this and the dev list, top or bottom 
responding, succinct message copying, and whether or not to leave a 
message intact while responding or slicing it and responding point by 
point have been some of the issues discussed in recent months.


I would like to respectfully ask that certain members of the list 
consider their method for posting new topics. I have noticed a problem 
with unrelated topics being folded into a single subject thread and from 
looking at message headers it seems this is because each of these topics 
was introduced by replying to a message and changing the subject instead 
of addressing a new message to the list. The result of this can be a 
thread which contains discussions of several different topics. This may 
further result in people not seeing your topic if it falls within a 
thread whose subject doesn't interest them.


An example would be the thread with the subject "Why can't LC do what 
PencilCase does?" Under that thread are 11 completely unrelated message 
threads, each having headers that indicate each new topic was initiated 
as a response to a previous but unrelated message within that thread.


It might be a more polite and better strategy to compose a new message 
to the list to introduce a new topic rather than doing it in a reply to 
a previous (unrelated) message.


Cheers,

Warren

Folks:
I’m putting out what I think is a fantastic idea for an app. It’s much more 
than I’d be willing to take on, but in the US, I think it could be very big. 
But, then again, perhaps it exists already. I’d like to use such an app for my 
aging stepmother. I release the idea into the livecode-sphere.

Problem: Aging population and seniors needing services, and wanting to live in 
their home as long as possible. Getting help is hit and miss and the senior 
help organizations do not actually work very well or consistently. I have been 
pondering this because my mother-in-law is 200 miles away and needs help to be 
able to stay in her home. The kind of app I propose, as the population ages 
further, could be extremely useful.

Solution: Think Uber. Folks who want to offer services to seniors, like take 
them to a doctor’s appointment, go shopping, clean the house, provide company 
(you get the idea).. sign up to the site. Seniors or their “primary overseer” 
(POS: a family member, or some agent who takes responsibility for overseeing 
the senior’s well-being) request services the same as they would do for an Uber 
ride. The service provider leaves notes re their specific experience giving the 
service, on a password protected database available to the POS.  The POS can 
rate the service provider and comment on their service quality. There could be 
a public area, managed by the POS, where public information about the senior 
could be posted.

Challenges would be creating some kind of certification for the service 
provider. Seniors are particularly vulnerable to fraud and abuse, so providers 
would need some kind of strong oversight. Probably it would be best if there 
was a local office for each location where providers were interviewed, checked 
for criminal records, possibly trained, etc. Perhaps a partnership with an 
existing non-profit senior help center would work.

Another challenge is that seniors may, for awhile, not be able to use a mobile 
device. The POS would help in this regard.

Social media would be very important in helping seniors find and evaluate 
appropriate providers and share ideas for strategies for independent living and 
needed care.

Best regards,
Bill

The selected dropdown remains in the extended position. Moving to

java has traditionally installed versions side-by-side. A new major

Richmond, you can play audioclips under Linux. I'm not sure what

a format/bit rate/sampling rate that plays, but it can work. For some 
reason some sounds (perhaps due to short length?) don't appear to play 
in the IDE but will play in a standalone. Download and experiment with 
Jacquie's Blocks. The woodtap doesn't play for me in the IDE but works 
in a standalone. The fanfare plays but is truncated in the IDE and works 
fine in the standalone. The sound used to signal the end of a game with 
blocks left plays as white noise instead of whatever it's supposed to 
sound like.

My issue was that I didn’t know of a command that I could run on the server, or

For future reference, anyone needing this and running on a Linux server

put shell("date -u")

which will return the current UTC time without any local timezone

You could look into fileType in the dictionary. I can recall having to 
explicitly set the file type for images saved from LiveCode or they 
would open in an editor because LiveCode was saving them as text files.


You could also try using 'get shell()' and whatever command or method 
you feel most appropriate given you content, to create the file and then 
make it executable by


'get shell("chomd +x /your/new/file")'

This works here under Linux and  work under OS X because the 
file itself is being created and saved by the system instead of by LiveCode.

Re: OS X - how to write to a file associated as a Unix executable

The issue is creating the proper file format so when the chmod creates it

Are you saying that saving a file from TextMate and chmoding it works 
but using Terminal and 'print "something-that-will-execute" > 
/output/file' or 'cat /working/file > /working/file-cloned' and chmoding 
that file doesn't?

What I am trying to do is within a LC application

1. put field "mytest" into URL "binfile:~/race"

This creates a file called race in the ~/ directory.

The problem is that when you do a chmod +rw race the file is still
recognized as textedit file and NOT a UNIX executable.

When you look at a file created with LC and chmod  verses a file created
with textmate and chmod you can see the differences in the finder or get
info on both files and see the difference.



I understand the problem. What I am asking you is if creating a file 
using the shell function in LC instead of saving it directly from LC 
works. I can't tell from your response if you have tried it.
The first step would be to get the path of a file you know does what you 
want it to do. Then open a terminal and type:


cat /file-that-works > /file-that-works-new

then:

chmod +rx /file-that-works-new

Does this file do what you hope? If it does then the next step is to do 
the same thing using LiveCode's shell function. This should give the 
same result as using a terminal.


get shell("cat /file-that-works > /file-that-works3")
get shell("chmod +rx /file-that-works3")

We are attempting to bypass LiveCode's unfortunate desire to save 
everything as a text file and create a hard association with TextEdit in 
OS X.


I'm a little curious also about how you are telling TextMate to create 
and/or save the file. Are you explicitly telling it to create a shell 
script?

There is no sales tax charged for any online sales in the US except for

depending on how your partnership/company is structured and how they

Compare what you get when you run 'echo $PATH' in a terminal to what you 
get when you run it in LiveCode using shell(). Make sure the directory 
that contains whatever executable you might be running is installed in 
or linked in a directory that is in the $PATH returned by LiveCode's 
shell function. It would appear that it isn't in this case. You can 
further test by running 'which [command]' in a terminal and see if it's 
located in one of the directories that 'put shell("echo $PATH")' 
returns. It's not about which shell (executable), it's about the env and 
the $PATH.

I understand your frustration, Richmond. I can't open LiveCode on my 
Linux machine running the current release of openSUSE (Leap). I can, 
however, run it under different release versions of openSUSE and have it 
open right now in a virtual machine running openSUSE Tumbleweed. The 
dictionary seems to work just fine. I have seen from your previous 
discussion of this problem that you've been willing to go to some 
lengths to get a working dictionary and I salute your perseverance. Have 
you ever tried opening LiveCode from the command line and selecting the 
dictionary to see if it gives you any useful messages?

When I do that it gives me this:

sandbox! See 
https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment for

Despite this message, the dictionary does open and display content. It's 
possible you'll get some other message which might be useful.


What happens if you put a browser on a card, assign it a URL and select 
the LC browse tool? Does it display content as expected?

Good to know the Dictionary works there, but let's explore your other
SUSE versions and see if we can get the boot issue resolved.

Bryan Lunduke works for SUSE, and recently wrote a very enthusiastic
review of LC 8 after running it on SUSE and Elementary:
<http://www.networkworld.com/article/3079523/application-development/review-livecode-8-is-freaking-incredible.html>


Have you run LC with ldd to see if it's unable to find an expected package?



Richard,

Yes, I saw the article and noticed he had tried it under openSUSE. He 
doesn't say in the article which version he used for his review, but he 
has mentioned elsewhere that he prefers a rolling release and uses 
Tumbleweed.


ldd doesn't show anything missing. Getting LiveCode to run under 
Tumbleweed requires no head scratching or additional installation of 
libs, using the official installation DVD and as well the geckoLinux 
spin (rolling version) in both the XFCE and Budgie flavors.


There's a thread on the dev list with the subject "LiveCode fails to 
open in openSUSE Leap".

Searching for that string gave me zero results, and searching for
"OpenSUSE" brought up many old threads.

URL?




I follow the lists locally, in my email client, so I can't provide you a 
URL. The thread was started on 6-23 on the LiveCode Developer List. Here 
is the content of the original post:


---(start quote)---

The 64 bit LiveCode IDE fails to open for me under openSUSE Leap 42.1. 
It was previously working under openSUSE versions 12.x and 13.x. While 
there was a period when it failed under Tumbleweed (rolling release), it 
works in at least the last two snapshots. Simple standalones work as do 
simple LC Server scripts.


The first few times I tried, the LiveCode splash screen hanged while 
loading the menu bar (the last text displayed) and the process had to be 
killed. Now the splash screen disappears after less than a second.


Here is the tail of the livecode_tools_log:
 Loading Script Editor...
Enter Script Editor Initialisation
Leave Script Editor Initialisation
Loading User Icon Libraries...
Enter User Libraries Initialisation
Leave User Libraries Initialisation
Loading Error Management...
Enter Errors Initialisation
Leave Errors Initialisation
Loading Menu Bar...
Enter Menus Initialisation
  Trying to get the platform
  Linux

Starting LiveCode from the command line returns this error:
"Error in 
`/home/warren/.runrev/components/livecodecommunity-8.0.2-rc-2.x86_64/livecodecommunity.x86_64': 
free(): invalid next size (fast): 0x04e84a80"


and sends this to stderr:
"Use of deprecated SAXv1 function setDocumentLocator
Got SIGIOT"

It's strange that SUSE built on older and newer libs both work while the 
current "main" version does not. Do these errors reveal any useful clues 
as to what might be done to get it working?


The shell prints a backtrace. Would this be helpful to see? Running 
LiveCode through strace using some particular option?


--- (end quote)---

To clarify the last sentence of the first paragraph of the original 
(copied here from the dev list) post, simple standalones and LiveCode 
Server do work under Leap, it's the IDE that is the problem.


openSUSE is quietly one of the more popular distros and Leap is the 
current "standard" release so it might be a good thing to get this 
figured out. I wonder what LiveCode does just after it gets the 
platform, as it finishes up the menus initialization. I posted the shell 
backtrace at:


<http://warren.ws/lc_cli_output.txt>

It should be noted that if I run the command several times, the 
backtrace will not consistently end with the same lines; sometimes 
aborting with more lines and sometimes fewer.


Thank you for looking at this :)

Good sleuthing so far.  Narrowing it down to the IDE is especially
useful, as it suggests something that may eventually affect standalones,
since of course the IDE is just a collection of stacks itself.

I'm not familiar with backtrace, but the output appears to be very
different from strace.  Have you run strace?  To get going I wouldn't
worry about flags, even the defaults would likely yield useful info.

What's the bug report ID for this?  Maybe the logs should be included as
attachments there.http://warren.ws/strace-LC-output.txt



Richard,

I never filed a bug report. I reported my problem in a reply to another 
release announcement fairly recently and didn't receive any comment from 
any of the devs that have been generously participating on this list so 
I (perhaps stupidly and/or unfairly) took that to mean there was little 
interest in tackling it. Linux is not anything like a single target and 
we've all seen the dreaded "we can't reproduce it here" response that 
has to be as frustrating to the devs as it is to those of us who have 
the problem :D I'm grateful for the interest you and Mark Wieder have 
shown. I'm not averse to filing or contributing to bug reports and will 
do so with your encouragement.


The strace output, run without any flags, is 2.4 MB and 27,000+ lines. 
It means nothing to me, dilettante that I am. You can find it here: 
<http://warren.ws/strace-LC-output.txt> If you can think of any flags 
which might make it more manageable or useful, I will be happy to run it 
again.

Tiemo,

x264 is only an encoder and does not need to be installed on a client 
machine to enable playback if that's your concern. Whether or not the 
videos are compatible will depend on thoughtful selection of encoding 
options. In this regard x264 offers almost unlimited opportunity to

 The Intel encoder has the 
advantage of using the gpu, where applicable, to accelerate encoding. If 
you've found something that works, it wouldn't be a bad decision to have 
a celebratory beverage of your choice and think about something else!

Now do the same thing, only this time, drag a regular push button into the new

Seems if the combo box is the first thing you get properties for after a

you get properties for something else first, the property inspector seems to 
work fine.

If you do this after you have been running for a while, chances are you will 
have already gotten the property inspector for something else and the test will 
be no good. I have already removed all the plugins so that is not an issue.

If others can reproduce this, I will submit a bug report. I am running

None of the unicode stuff works [for me]:
* set the useUnicode to true
* the unicodeText of field
* the unicodeFormattedText of field
No error messages; just empty.
Can anyone give me a clue as to what to do ?
Thanks,
Alain





Is this really the version you're using? That version is almost a year 
old and has been superseded by several newer versions.


Is this stuff that works for you in other versions of LiveCode but not 
in the version you want to use now?

It shows the same build number in the "About" screen. You have to wonder 
exactly where the mixup is.


As before, I don't find any of the problems running this in openSUSE 
that you have there. It is possible these are system isolated problems 
or perhaps distro specific. You should consider filing a bug report with 
all system specific information as you can imagine might be relevant.


To the devs -- it seems with recent changes some Linux users are having 
new issues with dependencies where they had previously been running 
LiveCode without problems. Might it be possible to provide a script 
which checks for all known requirements as well as any suggested libs 
(making sure to distinguish 32 and 64 bit versions as necessary!) and 
lists them as installed or missing, in a format a little less cryptic 
than running 'ldd'? Something like this could save a lot of head 
scratching and frustration! I don't know that the problems Richmond is 
experiencing are related to this sort of problem, but in many other 
reported instances of troubles, being able to easily and definitively 
identify missing libs would have been an enormous boon.

Mark,

If we assume this is a mislabeled dp4, I suppose it's possible there are 
problems resolved in the actual dp5 that we can't experience just yet, 
but the issues he's talking about here have plagued him for a few 
releases and do not exist on my system. This is troublesome from many 
perspectives. This, along with other issues experience by Linux users 
lately, does suggest a simple solution to identify dependency issues for 
Linux would be highly useful.


Release announcements have not been entirely consistent, with at least 
one recent release being announced on one list much earlier than on the 
other, and I am in agreement with those who think RunRev needs to find a 
better solution to pre-staging than the current implementation if we 
need to be cautious about downloading what are publicly linked versions.


I have no interest whatsoever in the headaches of attempting to build 
from source, thank you very much.

Ah, ok... maybe I missed something here. You're saying there was a

bit disconcerting - which version was that?

I'm not particularly worried about that. I just think it's silly to
download an unreleased version and then complain about it.

My confusion again, sorry. So RunRev is directing people to download
these versions? I missed that announcement. Maybe I should slog my way
through the Kevin thing after all.




There was recently a version announced on one list which I did not see 
announced on the other. It struck me as odd. I don't remember which and 
I'm sorry but I don't feel inspired to wade through the lists to figure 
it out. I wouldn't suggest it was anything more than an accidental 
oversight, btw.


Again, it doesn't matter if it's been announced. If it's placed in a 
publicly available download location, alongside other releases, it is 
"released". These are accessed from a plainly available link on the 
LiveCode .com website. The link is labeled "View All LiveCode 
Downloads". These unannounced versions have release dates and release 
notes. There is nothing to indicate these are merely "almost releases" 
and "not to be downloaded until some future date".


The staging process is missing a step and it's not the fault of the 
downloaders.

The process which sometimes results in improperly functioning builds or

Um, what is it you thought? I didn't say "I once heard somebody say

did look for it at the time. If I missed it, I will not have been the 
only one who has overlooked an announcement for one reason or another.


In any event, depending on these lists to prevent people from 
downloading publicly available software "until it's time" is wildly 
irresponsible and scolding or mocking someone for downloading such 
software is ridiculous. People regularly overlook or miss announcements 
and others might not be downloading immediately from the announcements 
but prefer to go to the download directory at some other convenient 
time. I'm pretty sure there is also hope that curious people are finding 
and downloading LiveCode with the expectation that they'll join these 
lists sometime after rather than vice versa. While it's possible to say 
many of us should know better, there are groups of people who can't and 
others for whom it may not be convenient.


The system is not in any way reliable, nor particularly defensible given 
there are any number of reasons why someone may encounter one of these 
not-ready-for-release releases.

Maybe I've completely failed to understand what it is you don't like

Would it be practical and feel cleaner to wrap your nested repeats 
inside a command, say,'doLoop'. When your 'if' condition in the nth 
repeat is met, you 'exit doLoop'. You only have to reference and check a 
condition once this way and you cleanly exit the entire nested structure 
exactly when and where the condition is found.


A useless example that works:

Create a card with four fields and a button. Put this script in the button:


 on mouseUp
   doLoop
   answer "exited loop"
end mouseUp

on doLoop
   repeat 10 times
  add 1 to field 1
  repeat 10 times
 add 1 to field 2
 repeat 10 times
add 1 to field 3
repeat 10 times
   if field 3 is 3 then exit doLoop
   add 1 to field 4
end repeat
 end repeat
  end repeat
   end repeat
end doLoop

For Linux users who have installed "single user", in their HOME

installed for all users, in /opt, will run into these kinds of issues, 
at least sometimes, perhaps depending on what you're attempting to do

"/opt/runrev/" and 'put shell("find $PWD")' returns file not

If 'volumes' doesn't work, maybe you can try

You can try 'put shell("df -h")' in the message box to see if it gives

For LiveCode purposes, yes. The dictionary does indicated, by omission

find the 'diskSize()' returns an unexpected and useless result here 
under openSUSE, despite the dictionary's indication that it is supported

Matt,

I would suggest dynamically  setting the width of the buttons to the 
formattedWidth of the buttons is the most correct thing to do. You may 
also set the height of the buttons the same way. You will find the 
actual space needed changes with font selection.


I have suggested always setting the height of text fields the same way 
but for some reason that doesn't seem to go over very well. Personally 
I'm not a big fan of fixed height text fields which cut off the 
contained text. This is very common to see in Linux with LiveCode things 
developed on other platforms, including the IDE.


In any event, maybe the worst approach, and also the most common, is to 
start dictating the font selection and size. You can never know what 
reasons the user may have for using a particular font or size.


Dynamic layout is really the best way to go whenever possible. Ask a web 
developer.

Richmond, you've been trying get help with this for some time now and I 
don't recall seeing anyone respond with anything really helpful for you. 
I suspect that it's because your project and your problem are rather 
specialized. What happens if you use your font in some other app? Does 
it work as you would expect it to in other apps or do you get the same 
substitutions? Is it a LiveCode issue or maybe a Windows issue? Does 
using revFontLoad resolve the problem on a test machine?


If you install the font using a script, you should be able to control 
where it goes. Why not out install it where Windows expects user 
installed fonts to be? Perhaps you could find a a utility to make a 
proper Windows installer and have it put your font where it needs to go?

Roger, what did your users find? I find that one needs to explicitly set 
the text font and the text size in order to get readable text in a 
standalone in Windows 7 and 8. Of course, setting the text size means 
users' system settings, which may reflect their own needs and 
preferences, are overridden. I don't believe this is an acceptable 
default practice.


I have filed a bug, which seems to have not generated any interest from 
the devs, with a stack and a screenshot of that stack in the IDE 
alongside its built standalone, as well as the example Windows 
standalone. http://quality.runrev.com/show_bug.cgi?id=10995

positioning stacks off screen in Linux

[Warren Samples]

One of the commonly suggested methods of hiding stacks is setting their 
location to something that places them out of the view window. This is 
not working correctly here under openSUSE/KDE/KWin. A stack's location 
is constrained to the available viewport unless it has been previously 
dragged and placed so that some part of it past the screen edge. Once 
that is done, a stack can be positioned anywhere outside the viewport 
until it is completely within it and we return to our original problem. 
In order for any part of a stack to be positioned outside the viewport, 
some part of it must already appear beyond a screen edge.


This does not happen under Windows. Do users of other Linux 
distros/DEs/window managers find this same behavior?

Trying this is Mint 9 in VirtualBox is even worse. Stacks cannot be 
moved completely out of view no matter what I try.

No, hiding the stack is completely different from moving it to a 
location outside the visible display area. For most purposes they serve 
the same practical effect, but not necessarily all. At any rate, this is 
something that should, if possible, behave the same on all platforms in 
order to avoid confusion or unpleasant surprises.

What's happening in your setup that makes hiding the stack impractical?



I am curious about the possibility of scrolling or sliding multiple 
windows as a fixed layout which is wider than the available screen. Of 
course hiding and showing windows is an option, but that's a different 
concept which isn't necessarily ideal. It might prove an interesting 
option on smaller displays.

Well . . .

The first thing is to get VirtualBox sorted out on your system.

The second thing is that Genymotion looks for the SDK which is hard to
locate:

~/android-sdks/sdk  (where '~' is your Home folder),

don't let yourself be distracted by 'android-sdk-linux'

after that it goes "all funny" about something that is supposed to be in
the /etc/init.d folder, but isn't; so you have to do some fiddling around,
and quite how the thing worked because of my fiddling around I cannot
really say.

After that things seem comparatively straightforward, and I suspect the
best way to
get an Android standalone onto one of the devices is by uploading it to
some website
and then downloading it from inside the emulated device.

Unfortunately right now I've got a lot of "extraneous stuff" on my
plate, but I hope, come
Sunday night I will be able to upload some reasonably pretty pictures to
the Forum.

Richmond.



Apparently installation woes are a YMMV kind of thing. I just installed 
without any headscratching at all. Just clicked through the dialogs as 
they came up and I was all set and running.

Thee or thou? Your post makes it sound like a universal Linux problem, 
using the term "inevitably". I don't know what to say about the 
instructions being wrong "(but that is normal for Linux)". I didn't read 
them. I just downloaded the installer and clicked away and "magically" 
everything worked, despite it being Linux.


One of the things that I find a little disappointing is the propensity 
for people to say on this list that there's a "linux" problem when they 
should say "I have a problem on my system". One of the reasons I tend to 
look into and respond to posts to this list about problems Linux users 
have is to help clarify when the issue is indeed a "linux" issue and 
when the issue might be local. Clarifying this can only help get at the 
root of a problem and hence a solution.


Further, I'm not interested in wasting time in the silly pursuit of 
convincing people to run Linux as their main OS, but we should be 
careful about not encouraging the exaggerated fear that Linux is just 
too much trouble to think about at all. This is a cross-platform 
developing environment and I think LiveCoders should be encouraged to 
keep it in mind as a viable platform for app deployment, and an 
"inevitably" hostile beast after all, to install for testing during 
development.

This is almost always a result of an email client reformatting messages

It would be very interesting to see instructions for installing

documentation provided with the software seems always out of date and 
inadequate and has not always been helpful in resolving issues. Getting 
VServer to work has been problematic at times and the most recent

Are you using the player object? LiveCode uses mplayer under Linux if 
it's installed. Do you have mplayer installed? The player won't display 
controls but you can use start and stop in scripts. I believe mplayer 
plays mp3 wma out of the box. It works here under openSUSE.

One additional note; you may find that you have to take special 
precautions to terminate your app and the mplayer process. Closing the 
app window may not actually end one or both of the processes. Putting 
something like:


on closeStack
   get shell("killall mplayer")
   quit
end closeStack

in the stack script will work in that case.

Re: Figuring out the correct height / width of scrollbars under Linux

Hi all,

is there a way to figure out how wide / heigh a scrollbar needs to be under

be 14 Pixels. Is there a difference between Windowmanagers?

Thanks in advance,

Under KDE, scrollbar width is a user settable property. I don't know 
what default is, I have it set to something narrower because, well, I 
like it. I'm not sure that you can reliably determine this. It would 
depend on your ability to determine the DE of the current session which 
is available as a LiveCode global under some distros but not others, and 
then grab the setting from a config file, if the distro/DE make it 
available and you know where it is. I don't know what to say about height.


Why are you finding this desirable? Do you have some consistent display 
issue you're trying to resolve one some particular distro? Are you sure 
you want to be setting this in the face of what might be a (different) 
user preference?

I don't know that there's any need to be so snarky. It's a fairly common

If only we can get people to stop nesting responses within quoted text,
