How can the event handler of a popup menu item determine which component was 
right-clicked upon to activate that menu?

Answer:

Use the PopupMenu.PopupComponent property to determine what control the menu was 
activated for:


1   procedure TForm1.PopupItem1Click(Sender: TObject);
2   begin
3     Label1.Caption := PopupMenu1.PopupComponent.ClassName;
4   end;



The form's ActiveControl property can also be used, however, the active control may not necessarily be the control that caused the popup menu to appear.
