Hello list,
I have a problem using Gtk-2.10.13 on DirectFB (1.0.0-rc2, 1.0.0 doens't
run for some reason) running on a mips device. At some point, my
application creates a GtkIconView with some icons in a GtkWindow. When
this window is destroyed, some memory is not freed. Most of this memory
is allocated here:
#0 malloc (bytes=273616) at malloc.c:834

at gtkwindow.c:4345
When the GtkWindow is destroyed, I see these calls:
gtk_window_unrealize()
--> gdk_window_destroy()
--> _gdk_window_destroy_hierarchy()
--> _gdk_windowing_window_destroy()
--> IDirectFBWindow_Close()
--> IDirectFBWindow_Release()
--> IDirectFBWindow_Destruct()
gtk_window_destroy()
gtk_window_finalize()
However, the GdkWindow and the allocated directfb resources are not
freed, gdk_window_finalize() (which would be called by
gdk_window_destroy_notify() after a DWET_DESTROYED event) is not called.
I'm not sure whether this is a bug in the program or somewhere else,
does anyone have an idea about this?
Best regards,
Simon
