/**
 * Tabbed dialog with extended features.
 * KTabCtl is very similar to TQTabDialog, with the following differences:
 * 
 * @li To avoid confusion, the API is almost identical with TQTabDialog.
 * @li Does not create any buttons, therefore KTabCtl is not limited
 * to dialog boxes. You can use it whereever you want.
 * @li emits the signal tabSelected(int pagenumber) when the user
 * selects one of the tabs. This gives you the chance to update the
 * widget contents of a single page. The signal is emitted _before_ the
 * page is shown.  This is very useful if the contents of some widgets
 * on page A depend on the contents of some other widgets on page B.
