/**
* SECTION:dnd
* @title: Drag And Drop
* @short_description: Functions for controlling drag and drop handling
*
* These functions provide a low level interface for drag and drop.
* The X backend of GDK supports both the Xdnd and Motif drag and drop
* protocols transparently, the Win32 backend supports the WM_DROPFILES
* protocol.
*
* GTK+ provides a higher level abstraction based on top of these functions,
* and so they are not normally needed in GTK+ applications.

2010-06-08 19:21:18 +00:00
