<h2>Detailed Description</h2>
44
<p>The QDragEnterEvent class provides an event which is sent to a widget when a drag and drop action enters it.</p>
45
<p>This event is always immediately followed by a <a href="qdragmoveevent.html">QDragMoveEvent</a>, so you only need to respond to one or the other event. This class inherits most of its functionality from <a href="qdragmoveevent.html">QDragMoveEvent</a>, which in turn inherits most of its functionality from <a href="qdropevent.html">QDropEvent</a>.</p>
46
<p>See also <a href="qdragleaveevent.html">QDragLeaveEvent</a>, <a href="qdragmoveevent.html">QDragMoveEvent</a>, and <a href="qdropevent.html">QDropEvent</a>.</p>
