Drag and Drop
|
|
|
|
<!-- ##### SECTION Short_Description ##### -->
|
|
functions for controlling drag and drop handling.
|
|
|
|
<!-- ##### SECTION Long_Description ##### -->
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
GTK+ provides a higher level abstraction based on top of these functions,
|
|
and so they are not normally needed in GTK+ applications.
|
|
See the <link linkend="gtk-Drag-and-Drop">Drag and Drop</link> section of
|
|
the GTK+ documentation for more information.
