I just try to define a window and later decide to make it visible:
Here are the two programs, I can understand the error message generated =
by the first
but not the one generated by the second
What am I missing?
How to make it happen?
from wxPython.wx import *
class MyApp(wxApp):
def OnInit(self):
frame =3D wxFrame(NULL, -1, "hello from wxPy")
#frame.Show(true)
self.SetTopWindow(frame)
return true
app =3D MyApp(0)
app.frame.Show(true)
app.MainLoop()
attribute error: MyApp instance has no attribute 'frame'
