Detailed Description

A GtkInvisible C++ wrapper class.

The Invisible widget is used internally in GTK+, and is probably not useful for application developers. It is used for reliable pointer grabs and selection handling in the code for drag-and-drop. If you ever need to implement manual drag-and-drop you might find this widget useful.
