 * This Widget extends the functionality of TQListView to honor the system

 *
 * There is a new signal executed(). It gets connected to either
 * TQListView::clicked() or TQListView::doubleClicked() depending on the KDE
 * wide Single Click/Double Click settings. It is strongly recommended that
 * you use this signal instead of the above mentioned. This way you donīt
 * need to care about the current settings.
 * If you want to get informed when the user selects something connect to the
 * TQListView::selectionChanged() signal.
 *
 * Drag-and-Drop is supported with the signal dropped(), just setAcceptDrops(true)
 * and connect it to a suitable slot.
 * To see where you are dropping, setDropVisualizer(true).
 * And also you'll need acceptDrag(TQDropEvent*)
 *
 * TDEListView is drag-enabled, too: to benefit from that you have to derive from it.
 * Reimplement dragObject() and (possibly) startDrag(),
 * and setDragEnabled(true).
