I don't believe the underlying wxPython ComboBox does anything with the=20=

text the user types in the field, but rather leaves it up to you to=20
decide whether you want to do some processing. PythonCard does not bind=20=

the EVT_TEXT_ENTER event, but you can handle the keyPress event, and do=20=

some processing if event.keyCode =3D=3D 13, otherwise just call=20
event.skip(). That way if the user presses Return you can add the text=20=

to the ComboBox list. You can use the keyPress or textUpdate event if=20
you want to look at the current text and then change the=20
stringSelection based on what the user has typed. I believe that by=20
default the selection will be changed only when the user clicks on the=20=

dropdown arrow.

If PythonCard is not behaving the same as the ComboBox in the wxPython=20=

demo then there could be a bug in the PythonCard component, but I'm=20
pretty sure it is working the same.
