Re: Strange display problem with gtk-win32 and VC++
On Sun, 7 Nov 2010, Tor Lillqvist wrote: no one ever wants to volunteer to help. Actually, that is not true. For instance, the ms-windows theme engine is now effectively maintained once again and compiles and maybe even works in gtk+ master. And for bulding the GTK+ stack for Windows (32- and 64-bit), I very much plan to stop doing it myself manually eventually, and instead just make use of the great work done by my colleague Fridrich ÿÿtrba who has set up cross-compilation of a lot of stuff (including the GTK+ stack) in the openSUSE Build Service (OBS). The Windows binaries etc in OBS are very usable already, the only slight problem is that they are found inside noarch RPM archives. (But at least 7zip handles RPM archives fine, I am told. For instance, the GIMP installer uses GTK+ stack binaries from OBS. What annoyes me is that plenty of people are doing that, and there is no central repository for dependencies. On 32bits, there is more or less gnuwin32, but you propose also your packages on the gtk site and i'm sure kde guys are doing that too. I fear that it will be the same for 64bits packages. I know 4 places where there are packages built with the mingw-w64 compiler and there might be more. What about joining forces and make one unique official repository for packages on Windows ?

Re: Good view on windows

It really is much faster and simpler than compiling on Windows. You can use Wine to test your program. beware that wine can't be a solution to everything. I had tested a feature of gdi that was not supported in wine. Hence i had to develop that part on windows itself. But yes, compilation/linking is muuuch faster when cross-compiling on linux Vincent Torri ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: libgnomecanvas
Hey, 2010/5/1 John Emmas john...@tiscali.co.uk: Is this an appropriate forum for asking questions about libgnomecanvas or does it have its own separate mailing list? Hello John, note that GnomeCanvas is deprecated, maybe you want to use GooCanvas [1] instead. Also, this page has info about some canvas libraries [2] [1] http://live.gnome.org/GooCanvas [2] http://live.gnome.org/ProjectRidley/CanvasOverview I've updated the informations of the Evas canvas in that page (very fast canvas, btw). It is not vector-based, contrary to most other canvas libraries listed in the page above (as they use cairo for the rendering). cheers Vincent Torri ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Re: MS Windows packages and modularity
On Tue, 21 Oct 2008, [EMAIL PROTECTED] wrote: 2008/10/21 Tor Lillqvist [EMAIL PROTECTED]: But I admit I don't have any *really* strong preference. If it really is so that the majority of people who distribute GTK+ apps on Windows would prefer that the pixbuf loaders were separate DLLs I can return to that. Is there anybody out there who prefers having built-in loaders? I think I prefer separate loaders, if I understand the trade-offs correctly. The app I package and distribute needs tiff/jpeg load and save, so having an extra copy of the libraries statically linked in to the gtk stack bulks up my zip unnecessarily. My app also includes libMagick, so I think I might have three copies of libtiff and libjpeg in my download at the moment, annoyingly. speaking of that, as there are other Windows library, not related to gtk, that may use libjpeg, tiff, png, etc..., woud it be possible to install them in a drectory not specific to GTK (like in Program Files/Common Files/generic, or something like that) ?

Gtk-CRITICAL with a GtkFileChooserDialog
Hey,
I create a GtkFileChooserDialog, then I set its current folder to my home
dir, then I create a GtkFileChooserButton.
When I run the prog, I get:
(test_gtk:22697): Gtk-CRITICAL **: gtk_file_system_path_to_uri: assertion
`path != NULL' failed
I have gtk+ 2.10.11
I would like to know what the problem is, please (problem from gtk, from
my code, etc...)

problem when setting several times a pixbuf in a gtk image
Hello,
I use the following function to draw a frame in a gtk_image:
static void draw_frame (long int frame_nbr)
{
GdkPixbuf *pixbuf;
const BYTE *rgb;
PClip vclip_rgb32 = ToRGB32::Create(vclip);
CPVideoFrame frame = vclip_rgb32-GetFrame(frame_nbr);
guint width = frame-GetDimension().GetWidth();
guint height = frame-GetDimension().GetHeight();
rgb = frame-ReadFrom('~').ptr;
gtk_widget_set_size_request (image, width, height);
pixbuf = gdk_pixbuf_new_from_data (rgb,
GDK_COLORSPACE_RGB, TRUE,
8, width, height, 4 * width,
(GdkPixbufDestroyNotify) g_free,
(guint8 *)rgb);
gtk_image_set_from_pixbuf (GTK_IMAGE (image), pixbuf);
g_object_unref (G_OBJECT (pixbuf));
}
The first time that I use this function, there's no problem, the pixbuf is
drawn.
But when I call this function another time, it segfault during
gtk_image_set. Does someone see what is wrong ?
thank you
Vincent Torri
