<hr><a name="_details"></a><h2>Detailed Description</h2>
A GdkDragContext C++ wrapper class.
<p>
<a class="el" href="classGFC_1_1Gdk_1_1DragContext.html">DragContext</a> provides 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.<p>
GTK+ provides a higher level abstraction based on top of this inteface, so it's not normally needed in GTK+ applications.
