Re: Help replacing GtkDrawingArea with GtkLayout

[Joël Krähemann <joel weedlight ch>]

Hi,

Didn't before but may be check the following:

g_object_set(G_OBJECT(layout),
  "app-paintable\0", TRUE, 
  NULL);

gtk_widget_set_events (GTK_WIDGET (layout),
  GDK_EXPOSURE_MASK 
  | GDK_LEAVE_NOTIFY_MASK 
  | GDK_BUTTON_PRESS_MASK 
  | GDK_BUTTON_RELEASE_MASK 
  | GDK_POINTER_MOTION_MASK 
  | GDK_POINTER_MOTION_HINT_MASK 
  );
