The widget should examine the event to see what data it <a href="tqdropevent.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="tqdropevent.html">TQDropEvent</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="TQDragMoveEvent"></a>TQDragMoveEvent::TQDragMoveEvent ( const <a href="tqpoint.html">TQPoint</a> & pos, <a href="tqevent.html#Type-enum">Type</a> type = DragMove ) </h3> <p> Creates a TQDragMoveEvent 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 TQDragMoveEvent yourself since these objects rely on TQt's internal state. <h3 class=fn>void <a name="accept"></a>TQDragMoveEvent::accept ( const <a href="tqrect.html">TQRect</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="tqrect.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="tqrect.html">TQRect</a> <a name="answerRect"></a>TQDragMoveEvent::answerRect () const </h3> <p> Returns the rectangle for which the acceptance of the move event applies. <h3 class=fn>void <a name="ignore"></a>TQDragMoveEvent::ignore ( const <a href="tqrect.html">TQRect</a> & r ) </h3> <p> The opposite of <a href="#accept">accept</a>(const <a href="tqrect.html">TQRect</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>. <!-- eof --> <hr><p> This file is part of the <a href="index.html">TQt toolkit</a>.
