Close form on a doubleclick

When I click the OK button, the form is closed, returning a mrOK. I want to do the same when a TListBox element is double-clicked. I thought to do that the following way:

When the OK button is pressed, the procedure OKBtnClick is called. When an element in the listbox is double clicked, the following procedure is called:

   procedure x.OnBoxDblClick (Sender: TObject);
   begin
      OKBtnClick(Sender)
   end;

However when I do this, the form is not closed. What am I doing wrong?

That's because your OK button has a ModalResult property which is not related to its handler.

To do the same with your ListBox change its handler to something like this:

--//--
procedure x.OnBoxDblClick(Sender: TObject);
begin
  OKBtnClick(Sender); // or any other code
  ModalResult := True;
end;
--//--

Look for ModalResult Property into the Delphi Help File.
