I've seen some programs that have a combination Combobox/Textfield.
So you can either enter text or choose text from the dropdown box.
When I tried to do this with Win32::GUI, I can type in that space,
but the program doesn't catch it, and instead gives me whatever was
What I want to do is take whatever text the user enters and add it to
the Combobox, storing the ten (or so) last strings, so that if they
want to reenter some text they had previously entered, they won't
have to retype it. I could have a Combobox below the Textfield, but
it looks better to have just one control there.
