Subclassing a ComboBox widget in a frame build with wxGlade

wxPython Users
1

Hello,
I am new to wxPython but staedily and slowly finding my way in.

I am building my GUI with wxGlade which works quite well after getting used to
its functionality.

I let wxGlade write my code in a file called myapp_gui.py. Then I use anthother
file myapp_controls.py to subclass the GUI created with wxGlade. I set up my
application in the file myapp.py.

In my GUI I have ComboBox for selecting among a number of choices. I would like
to create the choices available for the ComboBox from an function
provide_buildings_choice_choices which creates a list of all choices instead of
manually entering all choices in wxGlade.

How can I do this?
If I add the function to a method which I insert into my subclass the selection
dialog doesn't show the choices.

I would be glad if anyone can offer some help here.

I hope I described my problem in an understandable manner.

Thanks in advance and kind regards,
Timmie

Your list called mylist is not in list form, it is in sort of a
dictionary form; there should have been a syntax error shown to you.
Can't you just change that line from:

mylist = [house: 1, tent: 2, tower: 3, lighthouse:4]

to

mylist = ['house', 'tent', 'tower', 'lighthouse']

ComboBoxes take lists of strings to provide the choices.
