OnFirst event

Applies To
TQDBNavigator

Declaration
property OnFirst : TBtnPressEvent;

Description
When the first button (nbFirst) is pressed three things happen:

   first the BeforeAction event is triggered

   next if an OnFirst event handler has been assigned OnFirst is triggered
   and if not the attached QDB's FirstItem method is called.

   finally the OnClick event is triggered

This give some flexibility in responding to navigator buttons.
