gdkWindowSetUserData {RGtk2} | R Documentation |
For most purposes this function is deprecated in favor of
gObjectSetData
. 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.
