The GetActionAllowed method is called by the TakeEvent method and is used to synchronize toolbar buttons with the appropriate FormVCR action..
Example:
CASE ACCEPTED()
OF SELF.VCRRequest
IF SELF.GetActionAllowed(EVENT:Accepted,SELF.Window.Request) THEN
CHANGE(SELF.VCRRequest,SELF.Window.Request)
SELF.Window.OriginalRequest = SELF.Window.Request
SELF.TakeRequestChanged(SELF.VCRPrevRequest,SELF.Window.Request)
SELF.VCRPrevRequest = SELF.Window.Request
ELSE
IF SELF.NoRecords THEN
SELF.NoRecords = RECORDS(SELF.View)
IF NOT SELF.GetActionAllowed(EVENT:Accepted,SELF.Window.Request) THEN
SELF.Window.Request = SELF.VCRPrevRequest
CHANGE(SELF.VCRRequest,SELF.Window.Request)
SELF.UpdateWindow
ELSE
CHANGE(SELF.VCRRequest,SELF.Window.Request)
SELF.Window.OriginalRequest = SELF.Window.Request
SELF.TakeRequestChanged(SELF.VCRPrevRequest,SELF.Window.Request)
