The default action of the Help button will open the help system if you have
provided a path to the help text.
The default action of Ok and Cancel will run QDialog.accept() and QDialog.reject(),
which you can override by reimplementing slotButtonClicked(). The default
action of the Close button will close the dialog.

Note that the KDialog will animate a button press
when the user presses Escape. The button that is enabled is either Cancel,
Close or the button that is defined by setEscapeButton().
