<p><a class="el" href="class_qwt_panner.html" title="QwtPanner provides panning of a widget.">QwtPanner</a> grabs the contents of a widget, that can be dragged in all directions. The offset between the start and the end position is emitted by the panned signal.</p>
<p><a class="el" href="class_qwt_panner.html" title="QwtPanner provides panning of a widget.">QwtPanner</a> grabs the content of the widget into a pixmap and moves the pixmap around, without initiating any repaint events for the widget. Areas, that are not part of content are not painted while panning. This makes panning fast enough for widgets, where repaints are too slow for mouse movements.</p>
<p>For widgets, where repaints are very fast it might be better to implement panning manually by mapping mouse events into paint events. </p>
