How can I see who triggered an action in Delphi?

Question

When a TAction event fires, the \"Sender\" is always the action itself. Usually that\'s the most useful, but is it somehow possible to find out who triggered the action\'s OnExe

Answer 1

Instead of actions, just use a click event. Set all buttons to use the same event handler. Ideally, NOT named after the first button (you can rename it).

Here's the code:

Procedure TMyForm.DestinationButtonClickHandlerThing(Sender: TObject); 
begin
  if Sender = Btn_ViewIt then
  begin
    // View It
  end
  else if Sender = Btn_FaxIt then
  begin
    // Fax It
  end
  else if Sender = Btn_ScrapIt then
  begin
    // Scrap It
  end
  else 
    ....   // error
   ...
end;
