Right, but I'm saying, this will not change. It's not possible to extend a control beyond the window. It makes even less sense to resize the window to match text inside the control.
I think you might actually be talking about HEIGHT, not WIDTH. Can you clarify this? "Wider" is a qualification of width, not height. If you want the box to be TALLER, you should say so. This is already possible with the automatic editbox sizing, or multiline, as suggested above.
