<hr><a name="details"></a><h2>Detailed Description</h2>
The QDragMoveEvent class provides an event which is sent while a drag and drop is in progress.
<p> When a widget <a href="qwidget.html#setAcceptDrops">accepts drop
events</a>, it will receive this event repeatedly while the
drag is within the widget's boundaries. The widget should examine
the event to see what data it <a href="qdropevent.html#provides">provides</a>, and <a href="#accept">accept</a>() the drop if appropriate.
<p> Note that this class inherits most of its functionality from
<a href="qdropevent.html">QDropEvent</a>.
<p>See also <a href="draganddrop.html">Drag And Drop Classes</a> and <a href="events.html">Event Classes</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QDragMoveEvent"></a>QDragMoveEvent::QDragMoveEvent ( const <a href="qpoint.html">QPoint</a> & pos, <a href="qevent.html#Type-enum">Type</a> type = DragMove )
</h3>
<p> Creates a QDragMoveEvent for which the mouse is at point <em>pos</em>,
and the event is of type <em>type</em>.
<p> <b>Warning:</b> Do not create a QDragMoveEvent yourself since these
objects rely on Qt's internal state.
<h3 class=fn>void <a name="accept"></a>QDragMoveEvent::accept ( const <a href="qrect.html">QRect</a> & r )
</h3>
<p> The same as <a href="#accept">accept</a>(), but also notifies that future moves will
also be acceptable if they remain within the rectangle <em>r</em> on the
widget: this can improve performance, but may also be ignored by
the underlying system.
<p> If the rectangle is <a href="qrect.html#isEmpty">empty</a>, then
drag move events will be sent continuously. This is useful if the
source is scrolling in a timer event.
<p>Examples: <a href="desktop-example.html#x1727">desktop/desktop.cpp</a> and <a href="dirview-example.html#x1668">dirview/dirview.cpp</a>.
<h3 class=fn><a href="qrect.html">QRect</a> <a name="answerRect"></a>QDragMoveEvent::answerRect () const
</h3>
<p> Returns the rectangle for which the acceptance of the move event
applies.
<h3 class=fn>void <a name="ignore"></a>QDragMoveEvent::ignore ( const <a href="qrect.html">QRect</a> & r )
</h3>
<p> The opposite of <a href="#accept">accept</a>(const <a href="qrect.html">QRect</a>&), i.e. says that moves within
rectangle <em>r</em> are not acceptable (will be ignored).
<p>Example: <a href="dirview-example.html#x1669">dirview/dirview.cpp</a>.
