How do I determine the width of a TMainMenu? I want to ensure that the form is not 
resized to less than the width of the TMainMenu on the form.

Answer:

The menu bar will automatically wrap when that happens, so it is not a catastrophy. 
There is a GetMenuItemRect API function you may want to try to get the information 
you are after.

1   procedure TForm1.Button1Click(Sender: TObject);
2   var
3     r: TRect;
4     i: Integer;
5   begin
6     for i := 0 to mainmenu1.Items.Count - 1 do
7     begin
8       Win32Check(GetMenuItemrect(handle, mainmenu1.handle, i, r));
9       memo1.lines.add(format('Item %d: (%d, %d), (%d, %d)', [i, r.left, r.top, 
10  r.right,
11        r.bottom]));
12    end;
13  end;


Note that the coordinates returned are screen-coordinates.
