51
52The QDragMoveEvent class provides an event which is sent while a drag and drop is in progress.
53<p> When a widget <a href="qwidget.html#setAcceptDrops">accepts drop
54 events</a>, it will receive this event repeatedly while the
55drag is within the widget's boundaries. The widget should examine
56the event to see what data it <a href="qdropevent.html#provides">provides</a>, and <a href="#accept">accept</a>() the drop if appropriate.
57<p> Note that this class inherits most of its functionality from
58<a href="qdropevent.html">QDropEvent</a>.
59<p>See also <a href="draganddrop.html">Drag And Drop Classes</a> and <a href="events.html">Event Classes</a>.

61<hr><h2>Member Function Documentation</h2>
62<h3 class=fn><a name="QDragMoveEvent"></a>QDragMoveEvent::QDragMoveEvent ( const&nbsp;<a href="qpoint.html">QPoint</a>&nbsp;&amp;&nbsp;pos, <a href="qevent.html#Type-enum">Type</a>&nbsp;type = DragMove )
63</h3>
64
65<p> Creates a QDragMoveEvent for which the mouse is at point <em>pos</em>,
66and the event is of type <em>type</em>.
67<p> <b>Warning:</b> Do not create a QDragMoveEvent yourself since these
68objects rely on Qt's internal state.
69
70<h3 class=fn>void <a name="accept"></a>QDragMoveEvent::accept ( const&nbsp;<a href="qrect.html">QRect</a>&nbsp;&amp;&nbsp;r )
71</h3>
72
73<p> The same as <a href="#accept">accept</a>(), but also notifies that future moves will
74also be acceptable if they remain within the rectangle <em>r</em> on the
75widget: this can improve performance, but may also be ignored by
76the underlying system.
77<p> If the rectangle is <a href="qrect.html#isEmpty">empty</a>, then
78drag move events will be sent continuously. This is useful if the
79source is scrolling in a timer event.
80
81<p>Examples: <a href="desktop-example.html#x1727">desktop/desktop.cpp</a> and <a href="dirview-example.html#x1668">dirview/dirview.cpp</a>.
82<h3 class=fn><a href="qrect.html">QRect</a> <a name="answerRect"></a>QDragMoveEvent::answerRect () const
83</h3>
84
85<p> Returns the rectangle for which the acceptance of the move event
86applies.
87
88<h3 class=fn>void <a name="ignore"></a>QDragMoveEvent::ignore ( const&nbsp;<a href="qrect.html">QRect</a>&nbsp;&amp;&nbsp;r )
89</h3>
90
91<p> The opposite of <a href="#accept">accept</a>(const <a href="qrect.html">QRect</a>&), i.e. says that moves within
92rectangle <em>r</em> are not acceptable (will be ignored).
93
94<p>Example: <a href="dirview-example.html#x1669">dirview/dirview.cpp</a>.
