But I thought a wxComboBox does not use a wxListBox, but a native drop-down, 
just like wxChoice? Is there any other significant difference between 
wxComboBox and wxChoice, other than that wxChoice prohibits editing ?

I don't think I understand what you mean. You said earlier "Under MSW we 
could implement such function but I'm not sure if it can be done in wxGTK at 
all". That is why I thought using only already portable wxWidgets components 
would be the only practical way it could be done.

I have looked at the MSW code for wxComboBox and it doesn't seem obvious to 
me how to do it even under MSW (I am no Windows API expert ...). For wxGTK I 
have no idea.

I am confused ...
