I'm trying to set the cursor to a watch. The problem is that gdk_set_cursor() requires a gdk_window. How do I get the gdk_window of a gtk_window in C? I've seen examples for gtkmm and pygtk but I can't find the corresponding C function.
GdkWindow *gdk_window = gtk_widget_get_window(GTK_WIDGET(gtk_window));
or, pre GTK 2.14, but now disallowed:
GdkWindow *gdk_window = gtk_window->window;
