[Chicago] using wxPython gui application in c?

[Robert Ramsdell]

Hello Jolley.  I'm not sure what is going on with your code, but try
this for the Python side of things:

import wx

class MyApp(wx.Frame):
    def __init__(self, title='MyApp'):
        self.app = wx.PySimpleApp()
        self.title = title
        self.windowCaption = title
        wx.Frame.__init__(self,None,wx.ID_ANY, self.windowCaption,
                          size=(200,100),
                          style=wx.DEFAULT_FRAME_STYLE|
wx.NO_FULL_REPAINT_ON_RESIZE)

app = MyApp()
app.mainloop()

I posted a more elaborate example to the list last week.
