OnPrev event

Applies To
TQDBNavigator

Declaration
property OnPrev : TBtnPressEvent;

Description
When the prev button (nbPrev) is pressed three things happen:

   first the BeforeAction event is triggered

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

   finally the OnClick event is triggered

This give some flexibility in responding to navigator buttons.
