I am often using comboboxes on forms, but want something that allows more rapid data entry. This textctrl is designed to allow the user to quickly select from a list of choices by dynamically presenting matches in a dropdown below the textctrl. Similar implementations exist, notably http://wiki.wxpython.org/TextCtrlAutoComplete, from which a lot a lot of code is borrowed, but this is too complex for my needs.
The widget is designed to present a textctrl into which the user starts typing. Matches (configurable to matches at beginning or matches anywhere) to the typed text will appear in a dropdown box. Up and down arrow keys can be used to navigate among the matches. Enter key will populate the textctrl with the selected match. Tab key will expand the entered text to the current match. When text is entered that does not have a match, an option exists to allow the user to add this text to the choices available.
Note that this is still in the early changes. As of now, this has only been tested on Linux with Python 2.6 and 2.7 and WxPython 2.8.
