GTK+ window -> XID fails

i have GTK+ window

Quote:

HildonAnimationActor *actor;
GtkWidget *window, *drawing;

Quote:

window = hildon_stackable_window_new ();
gtk_widget_realize (window);
gtk_window_fullscreen (GTK_WINDOW(window));

Quote:

actor = HILDON_ANIMATION_ACTOR (hildon_animation_actor_new());
hildon_animation_actor_set_parent (actor, GTK_WINDOW (window));
drawing = gtk_image_new ();
gtk_container_add (GTK_CONTAINER (actor), drawing);

all looks good (window created,showed and so on). but when i try to get XID (to create EGL surface)

Quote:

XID winxid=GDK_WINDOW_XID((GdkDrawable*)(drawing));

winxid is zero
what's can be wrong?

Re: GTK+ window -> XID fails

I think "drawing" is not a GdkWindow; after realising it, you should call gtk_widget_get_window on it and use the XID macro on that

Re: GTK+ window -> XID fails

realize the image.
Then:
XID winxid=GDK_WINDOW_XID(GTK_WIDGET(drawing)->window);

Note that GdkWindow is not the same as GtkWindow.
