Re: [Pythoncard-users] ComboBox- Allows text entry, then ignores it?

[<gre...@co...>]

Kevin,

Your answer makes sense.  I guess all I really want to do is disable 
text entry so the user must choose one of the list items.  I'm wondering 
  if I'm using the wrong GUI component?  For example on a web form, a 
drop-down box type thing only presents the preset choices, so I just 
want a GUI version of that type of webform thing.

I'll  play with the resource editor a bit, see if there's something that 
already works like that.  Otherwise I'll look up how to just disable 
text entry.
