 Usage Notes
   ■ Use a LostFocus event procedure to verify and validate updates.
     LostFocus allows validation to take place as the user leaves the
     control.
 
   ■ You can use LostFocus for enabling, disabling, hiding, and displaying
     other objects, as you can with a GotFocus event. Or, you can reverse or
     change conditions you set up in the object's GotFocus event procedure.
     See: ◄GotFocus Event►
 
   ■ To enhance an application visually, set the color of a control when it
     gains or loses the focus. See: ◄Focus Definition►
