+/**
+ * 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
+ * @ref QListView::clicked() or  @ref 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 dont
+ * 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 @ref #dropped(), just @ref #setAcceptDrops(true)
+ * and connect it to a suitable slot.
+ * To see where you are dropping, @ref setDropVisualizer(true).
+ * And also you'll need @ref acceptDrag(QDropEvent*)
+ *
+ * KListView is drag-enabled, too: to benefit from that you've got derive from it.
+ * Reimplement @ref dragObject() and (possibly) @ref startDrag(),
+ * and @ref setDragEnabled(true).
