Wing IDE Pro trace back error but not on Eclipse/Pydev

by Devl Infonews :: Rate this Message:

Hi,

I am just learning Python and wxPython. Meanwhile I am also trying out Wing IDE Pro and Eclipse/Pydev and running through some of the example off of Noel Rappin's book wxPython in Action. The problem is I get the trace back error on Wing IDE but not on the Eclipse/Pydev IDE. Here is the code that simply tells the apps to redirect stdout and stderr:

#!/usr/bin/env python

import wx

import sys

class Frame(wx.Frame):

def __init__(self, parent, id, title):

print "Frame __init__"

wx.Frame.__init__(self, parent, id, title)

class App(wx.App):

def __init__(self, redirect=True, filename=None):

print "App __init__"

wx.App.__init__(self, redirect, filename)

def OnInit(self):

print "OnInit"

self.frame = Frame(parent=None, id=-1, title='Startup')

self.frame.Show()

self.SetTopWindow(self.frame)

print >> sys.stderr, "A pretend error message"

return True

def OnExit(self):

print "OnExit"

if __name__ == '__main__':

app = App(redirect=True)

print "before MainLoop"

app.MainLoop()

print "after MainLoop"

The error occurs when I close the last window. Wing points me to _windows.py on line 505. The trace back message is:

TypeError: in method 'new_Frame', expected argument 1 of type 'wxWindow *'

File "..../

File "/Users/melton/work/Python/wxPython/Stdout-redirect.py", line 27, in <module>

app.MainLoop()

return _core_.PyApp_MainLoop(*args, **kwargs)

File "/Users/melton/work/Python/wxPython/Stdout-redirect.py", line 22, in OnExit

print "OnExit"

File "//usr/local/lib/wxPython-ansi-2.8.8.0/lib/python2.5/site-packages/wx-2.8-mac-ansi/wx/_windows.py", line 505, in __init__

_windows_.Frame_swiginit(self,_windows_.new_Frame(*args, **kwargs))

Why does it occur on Wing and not on Eclipse/Pydev? I would be very happy with Wing IDE If this is a wxPython error that it caught.

My environment:

PowerPC Mac OS X 10.4.11

Python 2.5.2 - MacPython distribution from from python.org

wxPython 2.8.8.0

Wing IDE Pro 3.1.2-1

Eclipse 3.4

Pydev 1.3.18
