gdkWindowSetUserData {RGtk2} | R Documentation

## gdkWindowSetUserData

### Description

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.

### Usage

    gdkWindowSetUserData(object, user.data = NULL)

### Arguments

``object`` | a `GdkWindow`
``user.data`` | user data
