Declaration [src]

gdk_window_set_user_data (
  GdkWindow* window,
  GObject* user_data

Description [src]

For most purposes this function is deprecated in favor of g_object_set_data(). However, for historical reasons GTK+ stores the GtkWidget that owns a GdkWindow as user data on the GdkWindow. So, custom widget implementations should use this function for that. If GTK+ receives an event for a GdkWindow, and the user data for the window is non-NULL, GTK+ will assume the user data is a GtkWidget, and forward the event to that widget.



Type: GObject

User data.

The argument can be NULL.
The data is owned by the caller of the method.
