I do this sort of thing with a timesheet application I wrote. Here's
what I do:
''' Create the main screen. '''
def __init__(self, redirect=False, filename=None):
wx.App.__init__(self, redirect, filename)
dialog = loginDlg.LoginDlg()
self.username = dialog.userTxt.GetValue()
self.password = dialog.passwordTxt.GetValue()
loggedIn = dialog.loggedIn
if loggedIn != True:
As you can see, I call a wx.Dialog right after initializing my wx.App.
The dialog is modal, which keeps my wx.App from continuing to load. In
my dialog class, I have some authentication code that loops. The loop
allows the user to retry logging in. If the user hits "Cancel", then I
exit the application using the sys.exit(0) command.
Hopefully this code snippet gives you the general idea. Either way, I
highly recommend subscribing to the wxPython user's group. You'll
learn a lot and there are a lot of helpful (and knowledgeable) people
on there, including a couple of core developers.
