Declaration [src]

gtk_widget_register_window (
  GtkWidget* widget,
  GdkWindow* window

Description [src]

Registers a GdkWindow with the widget and sets it up so that the widget receives events for it. Call gtk_widget_unregister_window() when destroying the window.

Before 3.8 you needed to call gdk_window_set_user_data() directly to set this up. This is now deprecated and you should use gtk_widget_register_window() instead. Old code will keep working as is, although some new features like transparency might not work perfectly.

Available since:3.8
