</p><p>GTK+ has a rich set of functions for doing inter-process communication via
the drag-and-drop metaphor. GTK+ can do drag-and-drop (DND) via multiple
protocols. The currently supported protocols are the Xdnd and Motif
protocols. As well as the functions listed here, applications may need to
use some facilities provided for <code>Selection</code>s. Also, the Drag and Drop API
makes use of signals in the <code><a href="Graphics-UI-Gtk-Abstract-Widget.html#t:Widget">Widget</a></code> class.

</p><ul><li> The <code><a href="Graphics-UI-Gtk-General-Drag.html#t:DestDefaults">DestDefaults</a></code> flags specify what actions Gtk should take on behalf
of a widget for drops onto that widget. The given actions and any targets
set through <code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragDestSetTargetList">dragDestSetTargetList</a></code> only are used if <code><a href="Graphics-UI-Gtk-General-Drag.html#v:DestDefaultMotion">DestDefaultMotion</a></code>

</li><li> Things become more complicated when you try to preview the dragged data,
as described in the documentation for <code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragMotion">dragMotion</a></code>. The default
behaviors described by flags make some assumptions, that can conflict
with your own signal handlers. For instance <code><a href="Graphics-UI-Gtk-General-Drag.html#v:DestDefaultDrop">DestDefaultDrop</a></code> causes
invocations of <code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragStatus">dragStatus</a></code> in the handler of <code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragMotion">dragMotion</a></code>, and

latter is dramatic, when your own <code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragMotion">dragMotion</a></code> handler calls
<code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragGetData">dragGetData</a></code> to inspect the dragged data.

leaves the widget. A typical reason to connect to this signal is to undo
things done in <code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragMotion">dragMotion</a></code>, e.g. undo highlighting with <code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragUnhighlight">dragUnhighlight</a></code>

the cursor over the widget during a drag. The signal handler must determine
whether the cursor position is in a drop zone or not. If it is not in a drop
zone, it returns <code>False</code> and no further processing is necessary. Otherwise,
the handler returns <code>True</code>. In this case, the handler is responsible for
providing the necessary information for displaying feedback to the user, by
calling <code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragStatus">dragStatus</a></code>. If the decision whether the drop will be accepted or
rejected can't be made based solely on the cursor position and the type of
the data, the handler may inspect the dragged data by calling <code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragGetData">dragGetData</a></code>
and defer the <code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragStatus">dragStatus</a></code> call to the <code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragDataReceived">dragDataReceived</a></code> handler.
</p><p>Note that there is no <code>dragEnter</code> signal. The drag receiver has to keep
track of whether he has received any <code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragMotion">dragMotion</a></code> signals since the last
<code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragLeave">dragLeave</a></code> and if not, treat the <code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragMotion">dragMotion</a></code> signal as an "enter"
signal. Upon an "enter", the handler will typically highlight the drop
site with <code><a href="Graphics-UI-Gtk-General-Drag.html#v:dragHighlight">dragHighlight</a></code>.
