<a name="gtk3-Drag-and-Drop.description"></a><h2>Description</h2>
<p>GTK+ has a rich set of functions for doing inter-process communication
via the drag-and-drop metaphor.</p>
<p>As well as the functions listed here, applications may need to use some
facilities provided for <a class="link" href="gtk3-Selections.html" title="Selections">Selections</a>. Also, the Drag and
Drop API makes use of signals in the <a class="link" href="GtkWidget.html" title="GtkWidget"><span class="type">GtkWidget</span></a> class.</p>

gtk_drag_dest_set (<em class="parameter"><code><a class="link" href="GtkWidget.html" title="GtkWidget"><span class="type">GtkWidget</span></a> *widget</code></em>,
<em class="parameter"><code><a href="https://developer.gnome.org/gtk4/gtk4-Drag-and-Drop.html#GtkDestDefaults"><span class="type">GtkDestDefaults</span></a> flags</code></em>,
<em class="parameter"><code>const <span class="type">GtkTargetEntry</span> *targets</code></em>,

<em class="parameter"><code><span class="type">GdkDragAction</span> actions</code></em>);</pre>
<p>Sets a widget as a potential drop destination, and adds default behaviors.</p>
<p>The default behaviors listed in <em class="parameter"><code>flags</code></em>
have an effect similar
to installing default handlers for the widget’s drag-and-drop signals
(<a class="link" href="GtkWidget.html#GtkWidget-drag-motion" title="The “drag-motion” signal"><span class="type">“drag-motion”</span></a>, <a class="link" href="GtkWidget.html#GtkWidget-drag-drop" title="The “drag-drop” signal"><span class="type">“drag-drop”</span></a>, ...). They all exist
for convenience. When passing <a href="https://developer.gnome.org/gtk4/gtk4-Drag-and-Drop.html#GTK-DEST-DEFAULT-ALL:CAPS"><span class="type">GTK_DEST_DEFAULT_ALL</span></a> for instance it is
sufficient to connect to the widget’s <a class="link" href="GtkWidget.html#GtkWidget-drag-data-received" title="The “drag-data-received” signal"><span class="type">“drag-data-received”</span></a>
signal to get primitive, but consistent drag-and-drop support.</p>
<p>Things become more complicated when you try to preview the dragged data,
as described in the documentation for <a class="link" href="GtkWidget.html#GtkWidget-drag-motion" title="The “drag-motion” signal"><span class="type">“drag-motion”</span></a>. The default
behaviors described by <em class="parameter"><code>flags</code></em>
make some assumptions, that can conflict
with your own signal handlers. For instance <a href="https://developer.gnome.org/gtk4/gtk4-Drag-and-Drop.html#GTK-DEST-DEFAULT-DROP:CAPS"><span class="type">GTK_DEST_DEFAULT_DROP</span></a> causes
invokations of <code class="function">gdk_drag_status()</code> in the context of <a class="link" href="GtkWidget.html#GtkWidget-drag-motion" title="The “drag-motion” signal"><span class="type">“drag-motion”</span></a>,
and invokations of <a class="link" href="gtk3-Drag-and-Drop.html#gtk-drag-finish" title="gtk_drag_finish ()"><code class="function">gtk_drag_finish()</code></a> in <a class="link" href="GtkWidget.html#GtkWidget-drag-data-received" title="The “drag-data-received” signal"><span class="type">“drag-data-received”</span></a>.
Especially the later is dramatic, when your own <a class="link" href="GtkWidget.html#GtkWidget-drag-motion" title="The “drag-motion” signal"><span class="type">“drag-motion”</span></a>
handler calls <a class="link" href="gtk3-Drag-and-Drop.html#gtk-drag-get-data" title="gtk_drag_get_data ()"><code class="function">gtk_drag_get_data()</code></a> to inspect the dragged data.</p>
<p>There’s no way to set a default action here, you can use the
<a class="link" href="GtkWidget.html#GtkWidget-drag-motion" title="The “drag-motion” signal"><span class="type">“drag-motion”</span></a> callback for that. Here’s an example which selects
the action to use depending on whether the control key is pressed or not:</p>

that you have in your <a class="link" href="GtkWidget.html#GtkWidget-motion-notify-event" title="The “motion-notify-event” signal"><span class="type">“motion-notify-event”</span></a> handler.</p></li>
<li class="listitem"><p>During a timeout handler, if you want to start a drag after the mouse
