Re: [perl-win32-gui-hackers] Success with flicker-free windows!
Humm - for some reason I'm not getting all messages to this list - anyone else have that problem? The archive is also not up to date... I missed the start of the thread - Anyway my 2 cents Garside Trevor say on win32::GUI Users list flicker problem when resize window can be remove by set default class style to 0. In GUI.xs, RegisterClassEx : wcx.style = 0; // CS_HREDRAW | CS_VREDRAW; // TODO (default class style...) It's look better when resize main window. I don't have samples whith lot of flicker problem. So, don't know if it's sufficient. This is the 'fix' that I have been using for a while, and works well in most simple cases. However you can get horrendous striping when reducing the size of a window - the GUI Loft being one example. In my case I had one window which suffered this problem, I just had to create a class with CS_HREDRAW | CS_VREDRAW and suffer the flickering. 4.Graphics objects no longer show up (DCs don't seem to support WM_PRINT). 5.Setting WS_CLIPCHILDREN results in massive flickering (the opposite of what it used to do) and causes no background to show. Well, I don't really understand a lot of what you said, and I don't have any applications that flicker with the current GUI, so I guess I'd have to say that if *anything* gets broken by this enhancement, that it should definitely be an extra cost option, rather than the default. All my application widgets flickered when I resized the windows, especially tree and listviews. This fix prevents the erase-redraw mentality of Windows, which is a stupid way of doing things in the 1st place. It would be easy to add an option -noflicker to all windows so that you can explicitly say I want to use the non-flicker drawing routines. I will do this. I like the idea of the -noflicker option (assuming you can turn it on and off during runtime). If it works with no cost, then perhaps it could become the default in future versions? Flicker free resizes are so *much* better. Looking forward to seeing this fix in action.

Re: [win32gui] Re: [perl-win32-gui-hackers] Any release soon? (was: CVS Commits - bug fixes and enhancements)
We need to agree a version number for the next release. I would propose 1.01 - I think that we should be using a 2-digit second part of the version number to be CPAN friendly (See perldoc perlmodstyle), and don't see that there's enough change to justify anything other than incrementing the minor version by the smallest increment. 1.01 sounds fine by me. If we can agree the version numbering issue,. I'd be happy to make a release candidate available from my website. Cool:) I'll also write up my notes on building the PPM, so others can do it. I've added a note to my TODO list to look at adding a PPM target to the makefile (so we can just do nmake ppm (or whatever). I've also noticed that many of the document links with a page are broken, but don't have time to explore this further right now. I've noticed these broken links before, and have tried to fix a few of them when updating documentation. I suspect that the document parser could be improved a little to cope with the differing styles of text - it's a rather manual process otherwise. Cheers, jez.
Re: [perl-win32-gui-hackers] Tests
Does anyone have any experience with any of the GUI test packages that actually allow you to interact with a GUI in test, and if so what would people recommend? I work professionally as tester. GUI testing is part of my job :) (AutoIt, Win32::GuiTest and Rational Robot) Testing GUI apps can be a pain to do correctly, so it's good that we've got someone who knows what they are doing:) I'll write down my ideas and which module would fit best. The module (e.g. Win32::GuiTest) should be optional. It would be nice if we could use Win32::GuiTest simply because it's free and open:) But I don't know enough about the options to contribute. Leaving aside GUI testing, there is still quite a bit that could be done via the command line - things like testing destruction of controls/windows, creating lots of controls, testing for memory leaks etc. Cheers, jez.

[perl-win32-gui-hackers] Using Windows as Objects
Hi,
I've been putting together an example of several of the techniques I use
when building a GUI. One of the things I do is to use lots of child windows
to encapsulate many controls and functionality into one logical package.
This works really well for me, but is still on the 'messy' side, so I've
tried to encapsulate all functionality (event handling and method calls)
into a single perl object that could be used throughout the application.
The example below is rather simple, but should explain the concept. In a
hypothetical application, the user needs to be able to select the Employee
ID in lots of places in the application. As well as being able to type in
the ID directly, the user might also want to search for the ID. Rather than
create lots of individual controls, an object does all the work for you...
Except for when you exit, and a crash occurs (perl 5.6 GUI 1.02 Attempt to
free unreferenced scalar at C:/Perl/site/lib/Win32/GUI.pm line 3266). I do
create a circular link, with a closure being used to 'remember the object
(In my own application, the closure is of the window, not an object that
contains it, and this doesn't crash). I'm not sure if this is a bug within
win32-gui or my code?
Or is there a better way to create a perl object that can handle both method
calls and events?
Thoughts?
Cheers,
jez.

Re: [perl-win32-gui-hackers] Using Windows as Objects
This is a known bug with win32-gui. It is fixed by using perl 5.7 or later or using the circular ref patch Ok - I've created a tracker item so this issue isn't lost:) https://sourceforge.net/tracker/index.php?func=detailaid=1248578group_id=16572atid=116572 I've just ran that example under 5.8.7 and it still crashed? I posted to the list during the 1.02 release cycle. A similar section was applied some years ago, but removed because older perl don't allow circular refs at all. I just searched the archive but it doesn't show any attachments - could you forward it again so I can see if it fixes the problem? Cheers, jez.

It looks like we're not allocating enough space for the string - adding 1 to
cbString stops the crash (another issue is that we're assuming 1 byte = 1
char which might not be the case...).

RE: [perl-win32-gui-hackers] Crash in CommonMsgLoop
I apologies for using this forum as a sounding board... This is going to be a pain to track down. I've got a case where I'm almost guaranteed to cause a crash on exit - it's not a simple case Ok - think I've got it - just not sure what the fix should be - or even if a fix is needed. In my app, I catch the terminate event and ask the user if they are sure they wish to exit. If they say yes, I perform logic to save various settings. Once the settings have been saved I return -1, which should exit. During this exit phase (for some reason) various WM_NCHITTEST message are sent, and I assume that the window has already been destroyed(? - or perhaps some kind of timing issue, which explains why adding the print statements and Perl 5.6 don't cause the crash) - the crash happens when the function CallWindowProc is called. The 'fix' in my case is to hide the main window as soon as the user clicks on the yes button... Cheers, jez.

[perl-win32-gui-hackers] GUI_Events.cpp/DoEvent correct behaviour?
While tracking various crashes down I found myself in the DoEvent function in GUI_Events.cpp, now I don't think there is a issue here - but I did notice something surprising. I would have through that if a control was using NEM events, the OEM logic wouldn't be called for that control. For example, a button has a NEM click handler, I wouldn't expect DoEvent to look for OEM events such as MouseMove for the same button - but it does. If this is correct, it would mean that to save doing a perl_get_cv call (which is really inefficient) you would have to define all possible events for all controls? Add this line: printf(EventName %s \n,EventName); After: // OEM name event char EventName[MAX_EVENT_NAME]; strcpy(EventName, main::); strcat(EventName, perlud-szWindowName); strcat(EventName, _); strcat(EventName, Name); To see the amount of needless calls made... Cheers, jez.
Re: [perl-win32-gui-hackers] Crash with Combobox GetLBText
This would lead to a more complex macro/function, but would, I think be worth it. [snip] It would be a more complicated macro/function - but I agree with you, it would be worth it. This works nicely for the ANSI versions of the call, which return th ANSI encoded string of bytes that is suitable for directly inserting into the PV, but this doesn't address the Unicode issue at all, where the string copied by CB_GETLBTEXT would have to be converted from UCS-2 to utf-8 and then copied into the SV, setting the SVf_utf8 flag appropriately. If we spend time on reworking some of the internals for Unicode is it worth us considering the implications of 64bit further down the road? Cheers, jez.

Not really - as when you reduce the size of the application, the issue disappears. I'll keep an eye on it and as soon as I have something solid I'll raise a bug. Cheers, jez.

http://sourceforge.net/tracker/?func=detailatid=116572aid=1333060group_id=16572
Ok - it seems this is only an issue when SetEvent is used (see example
below, also on tracker).
What seems to happen is that the NEM event is called, and then it looks for
an OEM event - if found that is ran too.

The GUI did work with the same code before partitioning, all code in a

My suspicion is that you are letting the variable that holds your menu
object go out of scope, but with no code posted it's hard to tell. Try
using 'our $menu = ...' rather than 'my $menu = ...' when you create the
menu object. Letting things go out of scope is very easy to do when you
split code into modules.
I split my code in the same way you do, so I doubt that there is problem
with Win32::GUI::Dialog();
Another alternative might be that if you are using OEM events Win32-GUI
can't see your handlers, as they have do be defined in the main package. For
example, you might have had:
sub Button_Click {};
now it would have to be
sub ::Button_Click {};
Is this a perl implementation of an mph polynomial generator? I've already
re-worked the whole constants support (see the archive for this list a
couple of months back), and it currently uses a perl hash to hold the
constants and do the lookup, but given the potential number of constants in
the windows header files I was thinking of implementing a mph solution (and
have been playing with Taj Khattra's mph-1.2, which I have ported to
compile under MS VC++). A perl implementation that generates the
polynomial values to stick in the C code would be a nice way to solve the
problem that I have been struggling with of how to make a distribution
that others can easily add constants to.
Out of curiosity how much faster is a lookup using the mph-1.2 tool set V
the perl hash? How much smaller is the mph structure V the perl hash
structure?
In terms of distribution, couldn't we assume that anyone wanting to add a
constant would have (or need) the ability to build Win32-GUI from source? In
which case, couldn't the hash be built as part of the build process?

RE: [perl-win32-gui-hackers] an introduction
Hi, I exported the cvs source and began to familiarize myself with it. Once I feel comfortable with that, I will try and work on either some low priority bugs or feature requests that no one has taken up yet. If anyone has any suggestions, tips, unstated best practices, advice, or whatever, I'd welcome and greatly appreciate it. If you haven't already done so, create a sourceforge ID, and drop an email to Rob May who will give you permissions to check in code. As for advice...For me the biggest learning curve was perl XS - the perl documentation isn't ideal (for a starting point see perlxs and perlapi) - the best resource I've found is the book Extending and Embedding Perl by Tim Jenness and Simon Conzens. Most of the XS code for win32-GUI is straightforward. Choosing a low priority bug or feature requests is a good way to start - if it's just about learning, just play and ask questions:) If you think you'll be checking it in at some point, ask the list first as someone else might be working on the same thing. Rob is working on some big chunks of functionality, and some coordination might be required. All the best, and welcome to the team. Regards, jez.

Re: [win32-gui] RE: [perl-win32-gui-hackers] CVS Commit - More Win32::GUI::Constants changes
The only thing that concerns me is that the distribution is growing in size quite rapidly, and once things are in it's difficult to take them out. Is anyone concerned if the binary distribution doubles in size? How about if it trebles in size? I guess the real question is how do we decide what's in the core and what's not. Should we start separate distributions for some modules instead of having one large distribution? Personally I wouldn't mind if the binary distribution increased by 10 times - even then it would still be small compared to some toolkits!:) As long as the runtime sizes are kept the same (i.e., we're not loading modules if they aren't being used) and the exe generators (PAR, perl2exe perlapp) don't automatically include them - then there really isn't any issue other than bandwidth. There are other advantages of bundling them together - there is some shared code which could be removed, with other code simplified. Going forward, all these modules need to brought together anyway so we can support the NEM, improved class logic (via UserData type methods), Unicode and no doubt other things too:) We could always assume that the user will have these modules installed. Your win32-gui widget script for example, would show Perl code via Scintilla and link to the documentation (locally or on the web) via AxWindow (click on a method in the Scintilla window, and the documentation is shown). Cheers, jez.

I don't know how much that is, or if it can be done without making more dependencies or bigger hunks of stuff. I think Jeremy's comment was about sharing GUI.h (and other headers etc.) during the build process - not about increasing dependencies between modules. Yeah, there are also some helper functions that could become common across modules - even if they just get defined as macros. Cheers, jez.

I've added support for the Win32 AnimateWindow() API, as requested by tracker 1266930: https://sourceforge.net/tracker/index.php?func=detailaid=1266930group_id=16572atid=366572 Now, as well as $win-Show(), $win-Hide() you can use $win-Animate(). I had problems building under mingw - I had to set: #define WINVER 0x0501 in windef.h for it to build - after that, all tests pass, and the example runs (nice BTW!). Cheers, jez.
Re: [perl-win32-gui-hackers] [win32-gui] Re: Possible WinXP memory leak [Was:Commit]
As Rob said, this is primarily going to impact on an application that opens and closes many windows. At least the memory is more or less returned instantly on exit. Yeah - and as it looks like it's XP only we can assume that it's a windows thing rather than being a perl/win32-gui issue. Is there a Known Issues or limitations section somewhere in the documentation until this is eventually tracked down? Perhaps we should just update the tracker item, but leave it open for future reference? Cheers, jez.
[perl-win32-gui-hackers] Problems building with VC
Hi, I've got a box with VC6 on it and I'm trying to build Win32-GUI - I know I need to download the latest headers etc, but for the life of me (I've spent over an hour looking!) , I can't seem to find the correct place/right SDK? The errors below. Any suggestions? Cheers, jez. NOTE: WINVER has been defined as 0x0500 or greater which enables Windows NT 5.0 and Windows 98 features. When these headers were released, Windows NT 5.0 beta 1 and Windows 98 beta 2.1 were the current versions. For this release when WINVER is defined as 0x0500 or greater, you can only build beta or test applications. To build a retail application, set WINVER to 0x0400 or visit http://www.microsoft.com/msdn/sdk to see if retail Windows NT 5.0 or Windows 98 headers are available. See the SDK release notes for more information. *** Using Preserved Perl context.

Tracker 1417288 https://sourceforge.net/tracker/index.php?func=detailaid=1417288group_id=16572atid=116572 This bug report claims that the following code leaks memory: #!perl -w I don't see any leak with Win32::GUI v1.05, perl 5.6.1, 5.8.7, 5.8.8, Win98 or Win2K. Can anyone reproduce this leak (I'm particularly interested if this is a WinXP thing) or can I close the report? I've just tried to reproduce it in an old Win32-GUI environment and it was leaking - upgrading to the latest code (via CVS) fixes the issue (that bug report might have come from me!)

Hmmm. I wonder what's causing that. I had really hoped that I had resolved those destruction warnings. Are these warnings that you don't get with Win32::GUI v1.05? Yes, I dont get them with v1.05. The only thing that I can think of is that I use a lot of child windows and for some reason they are getting destoryed twice somehow? Any thoughts on the scintilla issue?

[perl-win32-gui-hackers] Crash with perl 5.10 and Win32::GUI 1.6
All,
I am getting a crash when using Perl 5.10 and Win32::GUI 1.6. The same
application doesn't crash under 5.8.7 or 5.8.8. I've tracked down the
problem, but I'm not convinced it's the actual underlying issue. The crash
was occurring at:
GUI_Helpers.cpp line 757 proc WindowsHookMsgProc
When I was selecting from the main menu of the application. The problem is the
line:
arrayref = av_fetch(perlud-avHooks, WM_TRACKPOPUP_MSGHOOK, 0);
where:
perlud-avHooks
contains zero (NULL)
Simply adding:
if (perlud-avHooks !=NULL ) {
before the call to the av_fetch stops the crash and the application runs
normally.
A potentially related issue is that I'm also getting:
Can't call method STORE on an undefined value during global destruction.
When the application exits. Again, this doesn't happen under 5.8.7 or 5.8.8. I
am therefore suspecting a reference count issue somewhere? Any thoughts? I am
going to try and create a simple test case.
Cheers,
jeremy.

It doesn't seem related to the crash. The stripped down example below is odd as
most of the code doesn't make sense (!) but if you comment out any of the lines
it doesn't show the error. The error happens with the stock Win32::GUI 1.6 ppm
and with the mingw built source under Perl 5.10 (activestate build 1002). I
suspect the hook method - but I'm lost...Thoughts?

Re: [perl-win32-gui-hackers] Crash with perl 5.10 and Win32::GUI 1.6
Hi,
I've spent some more time on this. I've created a bug report on sourceforge so
this isn't lost:
http://sourceforge.net/tracker/index.php?func=detailaid=1941241group_id=16572atid=116572
Ok - it's not a hook issue, it looks like its just the normal destruction
process which seems different under 5.10. Any changes to the code below (such
as commenting out a line) changes the destruction order and thus the message
isn't reproduced. Spent a while looking through the code,
(Win32::GUI::WindowProps) and I admit I'm stumped:) Is all this functionality
to support accessing the internals of an object? I thought that was deprecated
functionality?
As a side, I couldn't get Win32::GUI to crash because of this issue but it does
mean that the script doesn't finish correctly - which in turn could have other
issues (such as with PerlApp).
Cheers,
jez.

I've created the following tracker item for this issue:
http://sourceforge.net/tracker/index.php?func=detailaid=1941264group_id=16572atid=116572
I think the solution is straightforward but don't want to commit the code yet.
As a side, I use the Win32::GUI::Coolbar module from Robs homepage:

and it needs updating to run under 1.6 (constants). I don't mind updating this
module and would support it's move into the core.
