<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qdropevent.html">QDropEvent</a> class provides an event which is sent when a drag and drop action is completed.</p>
<p>When a widget <a href="../qtwidgets/qwidget.html#acceptDrops-prop">accepts drop events</a>, it will receive this event if it has accepted the most recent <a href="qdragenterevent.html">QDragEnterEvent</a> or <a href="qdragmoveevent.html">QDragMoveEvent</a> sent to it.</p>
<p>The drop event contains a proposed action, available from <a href="qdropevent.html#proposedAction">proposedAction</a>(), for the widget to either accept or ignore. If the action can be handled by the widget, you should call the <a href="qdropevent.html#acceptProposedAction">acceptProposedAction</a>() function. Since the proposed action can be a combination of <a href="../qtcore/qt.html#DropAction-enum">Qt::DropAction</a> values, it may be useful to either select one of these values as a default action or ask the user to select their preferred action.</p>
<p>If the proposed drop action is not suitable, perhaps because your custom widget does not support that action, you can replace it with any of the <a href="qdropevent.html#possibleActions">possible drop actions</a> by calling <a href="qdropevent.html#setDropAction">setDropAction</a>() with your preferred action. If you set a value that is not present in the bitwise OR combination of values returned by <a href="qdropevent.html#possibleActions">possibleActions</a>(), the default copy action will be used. Once a replacement drop action has been set, call <a href="../qtcore/qevent.html#accept">accept</a>() instead of <a href="qdropevent.html#acceptProposedAction">acceptProposedAction</a>() to complete the drop operation.</p>
<p>The <a href="qdropevent.html#mimeData">mimeData</a>() function provides the data dropped on the widget in a <a href="../qtcore/qmimedata.html">QMimeData</a> object. This contains information about the MIME type of the data in addition to the data itself.</p>
