/**
* This Widget extends the functionality of QListView to honor the system
* wide settings for Single Click/Double Click mode, AutoSelection and
* ChangeCursorOverLink (TM).
*
* There is a new signal executed(). It gets connected to either
* QListView::clicked() or QListView::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 don´t
* need to care about the current settings.
* If you want to get informed when the user selects something connect to the
* QListView::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(QDropEvent*)
*
* KListView is drag-enabled, too: to benefit from that you have to derive from it.
* Reimplement dragObject() and (possibly) startDrag(),
* and setDragEnabled(true).
