Hi All,
I have built gtk with target directfb. I have installed following pacakages: 1.gtk+-2.18.0 2.atk-1.28.0 3.cairo-1.8.0 4.glib-2.22.2 5.pango-1.26.0 6.pixman-0.12.0 7.DirectFB-1.2.7 8.FreeType 2-9.16.3 Now I am trying to run examples programs thats comes with gtk.While running the program one window comes with one mouse pointer and it freeze.I ran same program with gtk- x11 where I get a Hello world message with proper window.I am expecting same thing with gtk-direcfb. Just for debugging I tried putting one exit(0) before "gtk_widget_show (window)" function call.Then I got the following error: /*****************************************************/ (helloworld:2654): Gdk-CRITICAL **: gdk_drawable_get_colormap: assertion `GDK_IS_DRAWABLE (drawable)' failed /***************************************************** Could anyone please let me know how to resolve this ? Below is the code for reference. int main( int argc, char *argv[] ) { /* GtkWidget is the storage type for widgets */ GtkWidget *window; GtkWidget *button; /* This is called in all GTK applications.

Control ends here * and waits for an event to occur (like a key press or * mouse event). */ gtk_main (); return 0; } Thanks, Moutusi _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@... http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list |

Moutusi,
I have built/installed the same packages that you have on an arm system, and am having the same crash when calling "gtk_widget_show (window)" in helloworld.c. Have you been able to resolve the crash? Thanks, Roger

Thanks Moutusi. It seems that versions of GTK+-Directfb higher than
2.12 are broken or the DirectFB 1.4.2 version is not compatible with GTK 2.18 just yet. I've ended up installing the debian libgtk-directfb package. This has gtk+-2.12.12 and directfb 1.0.1. I was hoping to get working a newer version, but right now just having it working is great. One more question about DirectFB DirectFB 1.4.2 uses a config file called /etc/directfbrc. Directfb 1.0.1 does not seem to be accessing this file so I can configure the input driver, resolution, etc. Where does Version 1.0.1 get its configuration from? I want to use tslib for the input driver instead of linux_input. Thanks for the help.
