* 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
* TQListBox::clicked() or TQListBox::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 TQListBox::selectionChanged() signal.
