[Pythoncard-users] drop down menu

[Falco, O. <ori...@th...>]

Ok, here's what my GUI should do (or part of what it should do)......I
have a drop down box with the letters of the alphabet. Once the user
selects a letter, this should bring up a list of last names that start
with the selected letter. The list of last names is stored in a folder
where every letter has its own subfolder. How can I do this??????
