[wxruby-users] wxComboBox and wxTE_PROCESS_ENTER

[Mario Steele]

The problem lies in the fact, that Wx::ComboBox has a Drop down, and a Text
Edit in it.  I believe that Fabio wants the Enter event, so that he can add
what a person enters into the Drop Down, if I am understanding correctly.
The best thing to do, is to monitor evt_keypress, and create a new item, and
update that item in the combo box, as the person types stuff into it.
Either that, or monitor on focus lost, and check to see if the item is in
the combo box, if not, add it.  Though, that can lead to it's own problems,
as a person could switch between the controls several times, and have
several items added if he changes the text each and every time he tabs
between the controls.

Just a couple of suggestions on how to work around it.
