Re: which gtk-win32 version to use?
Thanks everybody for the answers.
So far, I've only found that one call to pango_layout_get_pixel_size() in my app
was followed by a segfault although the layout is valid, so this remains quite
confusing
(at least for me.)
Now I have one more question:
In the linux version, I use g_timeout_add_full() but in the win32 version, I
have
to use windows high resolution multimedia timers because the callback function
has
to be called every 5 ms (more exactly between 1 and 25 ms) and this doesn't
work with
g_timeout_add_full() under windows.
Here is the code for this:
...
GtkWidget *drawing_area
gintdrawing_area_width, drawing_area_height;
GdkDrawable *pixmap;
...
static gint callback_function1(...)
{
...
gdk_draw_drawable(
GDK_DRAWABLE(drawing_area-window),
gc, pixmap, x, 0, 0, 0,
drawing_area_width, drawing_area_height);
...
return TRUE;
}
#ifdef G_OS_WIN32
static void CALLBACK callback_function2(...)
{
...
callback_function1(...);
return:
}
#endif
...
delay = 5;
...
#ifndef G_OS_WIN32
g_timeout_add_full(G_PRIORITY_HIGH, delay, callback_function1, NULL,
NULL);
#else
/* getting highest resolution */
mmr = timeGetDevCaps(tc, sizeof(TIMECAPS));
win32_mmtimer_highest_res = tc.wPeriodMin;
/* setting highest resolution and some compatible delay */
timeBeginPeriod(win32_mmtimer_highest_res);
delay = MAX((unsigned)delay, win32_mmtimer_highest_res);
/* creating timer */
timer_id = timeSetEvent((unsigned int)delay,
win32_mmtimer_highest_res,
callback_function2,
dwUser,
TIME_PERIODIC);
if (timer_id == 0) {
error_message(Win32 mmtimer creation failed);
exit();
}
#endif
...
Although I don't see why, could this be a reason for the segfault?
(Again I'm trying to make sure that nothing else is involved.)
Thanks.
Manu

Another thing that helps to catch problems that you cannot reproduce
easily is Dr.Mingw, you can find it in the mingw-utils package. It's a
crash handler to be installed on the windows machine.
If you compile your source code with -gstabs debug symbols is able to
show you the stack trace of your program when it crashes.

Re: which gtk-win32 version to use?
Thanks for the quick answer. Actually, I got a ms visual c++ runtime error quite often saying: this app has requested the runtime to terminate it in an unusual way. Unfortunately, I don't know more about what was unusual... Manu TM On 09/28/2010 03:19 AM, Allin Cottrell wrote: On Tue, 28 Sep 2010, Manu wrote: I'm building an app for linux and windows.

That is just the message you get when abort() is called. Not really any more or less informative than the single-word message Aborted that Unix shells typically print... To find out what is happening you need to use a debugger. --tml ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
which gtk-win32 version to use?
Hi everybody, I'm building an app for linux and windows. I use gtk-win32 with mingw for the windows version. The linux version is very stable but the windows version sometimes randomly crashes. My question is: which gtk-win32 version is best to use? On the gtk website, it's said that gtk+ 2.16 is older but more reliable than gtk+2.20. (Of course, bugs in my port of the app are most likely the reason for these crashes but I'm trying to make sure that nothing else is involved.) Thanks for any hint.
