program crash on export snapshot

2012-10-26 Thread Tiemo Hollmann TB
Hi all,

I have a customer with a MacBook Pro, OSX 10.6.8, where my program crashes
when creating a snapshot from a video. The same program runs fine at all
other customers, so I think it has to be something on this specific Mac. I
couldn't debug it at the customer, but I assume the relevant two statements
(everything else is standard internal LC handling), which could cause the
crash are:

   set the alwaysBuffer of player myPlayer to true

   export snapshot from rect tRect to tScreenshot as PNG

Does perhaps anybody has experienced crashes related to these statements? I
am not very experienced in debugging Macs, can anybody give me a hint where
and what to look for?

Thank you

Tiemo

Re: iPad retina weirdness???

2012-10-26 Thread Pierre Sahores
And else, did you take care to rezise all the possible groups containing 
controls in your app ?

Le 25 oct. 2012 à 23:54, Lars Brehmer a écrit :

 So, after Colin and others solved my iOS simulator problem a few weeks ago, I 
 have now tried to sideload the app into my iPad and take a look.
 
 The stacks are, at least I believe, the correct size for the retina display, 
 accounting for the status bar, and are 1536 X 2008. All of the graphics were 
 made accordingly.
 
 So I compiled the iOS standalone, put it into iTunes and synced with the iPad.
 
 The icon showed and was perfect, the app launched but only the upper left 
 portion was visible! The good news is that the buttons in that portion of the 
 interface seemed to work ok, but again, just a quarter of the interface is 
 visible.
 
 In the standalone settings for iOS I saw nothing referring to the display 
 resolution, so I can't fix it.
 
 Could it be that liveCode 5.5.2 doesn't support retina display? I upgraded 
 from rev 2.8 to live code to livecode 5.5.2 in one leap just a few weeks ago, 
 so I am not all that familiar with it, as much as I love using it!
 
 Or am I missing something simple again??
 
 
 Cheers,

AW: program crash on export snapshot

2012-10-26 Thread Tiemo Hollmann TB
Hi,
I have got the crash logs from the console of my customer, but I am not able
to find any useful hints in there. I am not very deep into Macs...
Can anybody perhaps have a look into it and tell me, if you find any hint,
what could cause the crash and what I could look for on the customers
computer? 
Here is the link to the crashlog:

OK, two basic iOS questions (formerly iPad retina weirdness)

2012-10-26 Thread Lars Brehmer
Sorry if anybody reacted to this!

I finally found the iphoneUseDeviceResolution true function, and now it looks 
just like I meant it to look!

But the fact that I asked really underscores how behind I am on the learning 
curve of using liveCode for iDevices!

So my app looks very nice indeed, but two very basic problems with the 
functionality popped up.

First: I assumed that scrolling text fields were somehow handled automatically 
in iOS, that is a flick of the finger scrolls the field. I guess you all know 
that this is not the case! I have a scrolling list field which when the desired 
line is reached, mouseUp on it performs the desired operation. I found the 
iosScroller keyword and the BeginDecelerate and EndDecelerate, but 
unfortunately I couldn't figure out how to implement them!

A little help here?

The second one also involves a bad guess about what iOS automaticaly does. This 
one involves the keyboard. In iOS when you tap a field it appears. But in every 
app I have ever seen if the active field is at the bottom of the app, the 
entire app slides up, so the keyboard does not prevent you from seeing what you 
are typing. But it's not automatic. Does anyone know how to do this?

I am astonished at how fantastic liveCode works with iOS and was amazed to see 
that almost everything works smoothly on the first try, even for someone with 
my limited skills! But htese two very basic things are crucial, so I am looking 
for tips!

Cheers,

Lars

Hi Lars,
happy that you found iphoneUseDeviceResolution :-)

So,
about iOS scrolling, see this discussion on the forum : 
http://forums.runrev.com/viewtopic.php?f=49t=13141 ...


about the keyboard ... nothing in iOS is automatic... you have to do 
manually, eg. grouping the controls and moving up/down the group 
following the keyboard status ...

Retina scale factor versus display metrics

2012-10-26 Thread Thomas McGrath III
I don't have any Android devices to test with and I am wondering how to deal 
with Retina scale factor versus display metrics for Android development. 

I thought that display metrics where just the categories that different 
physically sized Android devices fit into and not the actual doubling of pixels 
like with retina displays. I thought I heard of other phones that have retina 
like displays at different scales (1.5) I believe but this display metric seems 
different than that.

Also, what does the Display Metrics return? The docs mention absolutely 
nothing. I looked Display Metrics up on the internet and got all kinds of 
different approaches and results for this like DisplayMetrics.DENSITY_LOW and 
ldli and display independent pixels versus actual pixels and in Livecode we 
have one logical 'point' mapped to two physical 'pixels' which don't reference 
dpi at all.

 The best I found is this:

DisplayMetrics.density is the logical density of the display, i.e. a value of 
0.75 (ldpi), 1.0 (mdpi), 1.5 (hdpi) or 2.0 (xhdpi). Multiply this value by 160 
to get the screen density expressed as dots-per-inch, i.e. a value of 120 
(ldpi), 160 (mdpi), 240 (hdpi) or 320 (xhdpi).

But this can't be used as a multiplier of pixels like the retina result, or can 
it? And if so, are there really that many retina/pixel doubled displays out 
there?

I double the size of my standard livecode controls to get a retina pixel so 
should I be multiplying the density result to get a true scale for standard 
livecode controls? Is this the size and width, height of a device or the 
virtual screen size of a devices retina or not screen?

Thanks

Tom

Re: Option Button in a Datagrid

2012-10-26 Thread Peter Haworth
Hi Glen,
I don't recall seeing that behavior but it's been quite a while since I was
working on this issue.  In fact, I came across it when working on my
SQLiteAdmin program which I believe you have.  You might want to check out
how it behaves.

Go to the Browse screen, select a table, then select New Filter from the
filter menu.  In the lower of the two datagrids, there is a column named
Operator with an option menu in it.  Play around with that and let me
know if it behaves in the same way as your datagrid column.  If it doesn't
show the problem you're having, I'll take a look at the code and see if I
can spot anything.

 Hi Pete,

 Yes this does work... all the text is readable!

 The only side effect is that after making a selection from an option box is
 that the hilite of the box remains ie the option box has a white background
 -- user makes selection -- the background color of the box remains
 hilited (in my case a dark blue) where as it should return to white.

 After playing with three rows with option buttons I find that sometimes a
 button will go back to a white background but it is not consistently
 reproducible.

 Have you seen this before? It happens in either case if the line is the
 current line or when the line is not the current line.

 At least for now it is functional next is to get a consistent look.

  Hi Glen,
  Are you on Windows?  IF so, I ran into this a few months back.  I filed
 bug
  report# 9993 about it and got the following reply from the QCC:
 
  Having had a look at your project, I think I've spotted the issue. It
  appears to be that the dataGrid property dgProp[hilited text color] is
  setting the foreground color of your dropDown menu to white, causing
  unhighlighted options to blend into the background.
 
  Either set the property to a different color or edit the setprop
  dgHilite handler in the columns behavior.
 
 
  Here's what I did to fix it.  Check the Datagrid manual for how to set
  up a column behavior script for your option menu columns.  When you've
  done that, find the setprop dgHilite handler and change it so only
  the set the foregroundcolor of me to empty line is in there, in
  other words get rid of the if statement.
 
  That fixed it for me, hope it works for you.

 If you turn off auto hilite for the datagrid then everything with

Re: Retina scale factor versus display metrics

2012-10-26 Thread Thomas McGrath III
Richard, Thanks for the reply. But that does not really answer the question of 
wether the new mobilePixelDensity is actually based on pixel doubling (halving, 
tripling, whatever) or just of categorized screen sizes as my searches on the 
internet seems to be saying. 

In other words is the new mobilePixelDensity a true actual density of the 
screen or just a trick to group different sized screens into manageable groups 
and figure out a 'rough' screen percentage using DPI?

Also, on Android does this return Denisty_Low or ldli or does it return 0.75 ?

Thanks again,

I do honestly believe that the new mobilePixelDensity function will

If anyone know otherwise it might merit a bug report, since the specific

Reading the QCC report you submitted for this, I see comments that this

It isn't automatic, the whole thing needs to be scripted. I checked for

Re: Script problem

2012-10-26 Thread charles61
Dick,

As far as I can tell, the problem had to do with other marked cards that had 
checkboxes despite not having a custom property. When I initially tested my 
code with a sample stack, all of the cards were marked and had checkboxes with 
custom properties. 

In my actual project, there were marked cards but some of the cards did not 
have checkboxes with custom properties. When I added a little bit more code to 
catch my empty custom properties, my code was working again without the 
insertion of five blank lines.  Despite Therry's code to identify checkboxes 
that had my custom property, I had cards identified as having checkboxes with 
custom properties when there were none on the cards. Again, I checked all of my 
checkboxes several times and could not find any with blank strings for custom 
properties.

 Anyone tried the new $249 Chromebook?

It's beyond me why anyone would. Do you know anyone who would go out of their
way to get version 1.0.0 of anything that didn't start with an i?

LiveCode won't run on it.
You can't write LiveCode apps for it.
It runs Google OS.
It's got an ARM processor.

I think it's a hardware version of a web browser.

Re: tock.aiff

 Here's a direct link to the file http://qery.us/2m9

Hi Mark, interesting problem with this file. First, I have a similar aiff
file called shortbeep which I use for error keys and inputs, and it works
fine. I was sent 3 different versions of tock.aiff and I can't get any of
them to work. All are 9k aiff files, they all make the tock sound when
played in iTunes, but when I replace shortbeep.aiff with tock.aiff in the LC
app, I don't get any sound at all. Any ideas? (I'm using the same code for
both sounds, but only shortbeep makes a sound).

Thanks
-- Mark

PS is there anyway to adjust the volume of a sound through script control?

I don't know if this would apply to your situation, but something 
identical happened to me on an Android device. It took me three days to 
track it down. Apparently the duration of the sound file was too short. 
I had to add silence to the end to make it last longer than a second or 
so. After that it would play.


The thing is, even the original very short files played in the IDE so 
that may not be what's wrong here. But you could try editing the files 
in a sound editor if nothing else works.

See playLoudness in the dictionary. Why it doesn't have the word 
sound or volume in its name is a secret only the MetaCard creator 
knew. I can never remember it.
