+ *
+ * This Widget extends the functionality of TQIconView to honor the system
+ * wide settings for Single Click/Double Click mode, Auto Selection and
+ * Change Cursor over Link.
+ *
+ * There is a new signal executed(). It gets connected to either
+ * TQIconView::clicked() or TQIconView::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
+ * TQIconView::selectionChanged() signal.
