<p><a href="qgraphicsview.html">QGraphicsView</a> inherits the drag and drop functionality provided by <a href="qwidget.html">QWidget</a>. When it receives a drag and drop event, it translates it to a QGraphicsSceneDragDropEvent.</p>
<p>QGraphicsSceneDragDropEvent stores events of type <a href="qevent.html#Type-enum">GraphicsSceneDragEnter</a>, <a href="qevent.html#Type-enum">GraphicsSceneDragLeave</a>, <a href="qevent.html#Type-enum">GraphicsSceneDragMove</a>, or <a href="qevent.html#Type-enum">GraphicsSceneDrop</a>.</p>
<p>QGraphicsSceneDragDropEvent contains the position of the mouse cursor in both item, scene, and screen coordinates; this can be retrieved with <a href="qgraphicsscenedragdropevent.html#pos">pos</a>(), <a href="qgraphicsscenedragdropevent.html#scenePos">scenePos</a>(), and <a href="qgraphicsscenedragdropevent.html#screenPos">screenPos</a>().</p>
<p>The scene sends the event to the first <a href="qgraphicsitem.html">QGraphicsItem</a> under the mouse cursor that accepts drops; a graphics item is set to accept drops with <a href="qgraphicsitem.html#setAcceptDrops">setAcceptDrops()</a>.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="acceptProposedAction" />QGraphicsSceneDragDropEvent.acceptProposedAction (<i>self</i>)</h3><p>Sets the proposed action as accepted, i.e, the drop action is set to the proposed action. This is equal to:</p>
<pre> setDropAction(proposedAction());</pre>
<p>When using this function, one should not call <tt>accept()</tt>.</p>
