How to check which control previously had focus (Views: 28)
Problem/Question/Abstract: Is there any way to tell within the OnEnter handler of Control2, which other control just passed the focus to Control2? Answer: type TForm1 = class(TForm) { ... } public LastControl: TComponent; end; procedure TForm1.Edit1OnEnter(Sender: TObject); begin if Assigned(LastControl) then { do whatever you want with the previous control } LastControl := Sender as TComponent; end; procedure TForm1.FormCreate(Sender: TObject); begin LastControl := nil; end; |
