TQIconViews are able to use this information to +paint the dragged items in the correct positions. Internally +TQIconDrag stores the data associated with drag items in +<a href="qicondragitem.html">TQIconDragItem</a> objects. +<p> If you want to use the extended drag-and-drop functionality of +TQIconView, create a TQIconDrag object in a reimplementation of +<a href="qiconview.html#dragObject">TQIconView::dragObject</a>(). Then create a TQIconDragItem for each item +which should be dragged, set the data it represents with +<a href="qicondragitem.html#setData">TQIconDragItem::setData</a>(), and add each TQIconDragItem to the drag +object using <a href="#append">append</a>(). +<p> The data in TQIconDragItems is stored in a <a href="qbytearray.html">TQByteArray</a> and is +mime-typed (see <a href="qmimesource.html">TQMimeSource</a> and the +<a href="http://doc.trolltech.com/dnd.html">Drag and Drop</a> +overview). If you want to use your own mime-types derive a class +from TQIconDrag and reimplement <a href="qmimesource.html#format">format</a>(), <a href="#encodedData">encodedData</a>() and +<a href="#canDecode">canDecode</a>(). +<p> The fileiconview example program demonstrates the use of the +TQIconDrag class including subclassing and reimplementing +dragObject(), format(), encodedData() and canDecode().
