<p>When a widget <a href="qwidget.html#acceptDrops-prop">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 kind of data it <a href="qdropevent-qt3.html#provides">provides</a>, and call the <a href="qdragmoveevent.html#accept">accept</a>() function to accept the drop if appropriate.</p>
<p>The rectangle supplied by the <a href="qdragmoveevent.html#answerRect">answerRect</a>() function can be used to restrict drops to certain parts of the widget. For example, we can check whether the rectangle intersects with the geometry of a certain child widget and only call <a href="qdropevent.html#acceptProposedAction">acceptProposedAction()</a> if that is the case.</p>
<p>Note that this class inherits most of its functionality from <a href="qdropevent.html">QDropEvent</a>.</p>
<p>See also <a href="qdragenterevent.html">QDragEnterEvent</a>, <a href="qdragleaveevent.html">QDragLeaveEvent</a>, and <a href="qdropevent.html">QDropEvent</a>.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QDragMoveEvent" />QDragMoveEvent.__init__ (<i>self</i>, <a href="qpoint.html">QPoint</a> <i>pos</i>, <a href="qt-dropactions.html">Qt.DropActions</a> <i>actions</i>, <a href="qmimedata.html">QMimeData</a> <i>data</i>, <a href="qt-mousebuttons.html">Qt.MouseButtons</a> <i>buttons</i>, <a href="qt-keyboardmodifiers.html">Qt.KeyboardModifiers</a> <i>modifiers</i>, <a href="qevent.html#Type-enum">QEvent.Type</a> <i>type</i> = QEvent.DragMove)</h3><p>Creates a <a href="qdragmoveevent.html">QDragMoveEvent</a> of the required <i>type</i> indicating that the mouse is at position <i>pos</i> given within a widget.</p>
<p>The mouse and keyboard states are specified by <i>buttons</i> and <i>modifiers</i>, and the <i>actions</i> describe the types of drag and drop operation that are possible. The drag data is passed as MIME-encoded information in <i>data</i>.</p>
<p><b>Warning:</b> Do not attempt to create a <a href="qdragmoveevent.html">QDragMoveEvent</a> yourself. These objects rely on Qt's internal state.</p>
<h3 class="fn"><a name="QDragMoveEvent-2" />QDragMoveEvent.__init__ (<i>self</i>, <a href="qdragmoveevent.html">QDragMoveEvent</a>)</h3><h3 class="fn"><a name="accept" />QDragMoveEvent.accept (<i>self</i>)</h3><p>The same as accept(), but also notifies that future moves will also be acceptable if they remain within the <i>rectangle</i> given on the widget. This can improve performance, but may also be ignored by the underlying system.</p>
<p>If the rectangle is empty, drag move events will be sent continuously. This is useful if the source is scrolling in a timer event.</p>
<h3 class="fn"><a name="accept-2" />QDragMoveEvent.accept (<i>self</i>, <a href="qrect.html">QRect</a> <i>r</i>)</h3><h3 class="fn"><a name="answerRect" /><a href="qrect.html">QRect</a> QDragMoveEvent.answerRect (<i>self</i>)</h3><p>Returns the rectangle in the widget where the drop will occur if accepted. You can use this information to restrict drops to certain places on the widget.</p>
<h3 class="fn"><a name="ignore" />QDragMoveEvent.ignore (<i>self</i>)</h3><p>The opposite of the accept(const <a href="qrect.html">QRect</a>&) function. Moves within the <i>rectangle</i> are not acceptable, and will be ignored.</p>
<h3 class="fn"><a name="ignore-2" />QDragMoveEvent.ignore (<i>self</i>, <a href="qrect.html">QRect</a> <i>r</i>)</h3><p>This is an overloaded member function, provided for convenience.</p>
<p>Calls <a href="qevent.html#ignore">QDropEvent.ignore</a>().</p>
