Inserting this line: self.listbox2.InsertItems([choice],0)
in your OnListBox1 method after your if/then/else statement puts the item you select in ListBox1 appear in ListBox2. You have to force choice into a list, otherwise it will insert each individual letter in the string into the box one at a time. Docs: http://wxwidgets.org/manuals/stable/wx_wxlistbox.html#wxlistbox Now, admittedly, this is on a Windows XP machine, but I don't think that such basic functionality would be different between platforms.
