[pydev - Users] import problems with wxPython

I've been having issues with getting eclipse to use the wxPython library.
First of all the python command shell imports and uses the library without any
problems.
Eclipse doesn't give an error when importing, but gives one when trying to use
anything inside the library.
For example, the following code work outside of eclipse:
import wx

app = wx.PySimpleApp()

frame = wx.Frame(None, -1, "Hello World")
frame.Show(1)

app.MainLoop()

But in eclipse the following errors are given:
Undefined variable from import: Frame
Undefined variable from import: PySimpleApp

What's most puzzling is when I run the following in eclipse:
for i in dir(wx):
    print i

All the classes are printed out fine, including the Frame class that it claims
doesn't exist.
I've tried adding everything I can think of to the PYTHONPATH, but nothing
works.
Adding the wx folders, the wx.pth file, nothing works. I've tried searching
google and this forum, but  no solutions have come up. Any ideas?
Thanks

Hi,

Here, having 'wx' in the forced builtin makes it work (it's actually there by
default). So... can you give some details on your installation?
- What's your OS
- Eclipse / Pydev version
- Do you have something in your error log? (see
http://pydev.sourceforge.net/faq.html#how_do_i_report_a_bug to know how to get
it)

Cheers,

Fabio

Just realized after posting I forgot those details.
Os: Windows Vista
Eclipse version: 3.2.2
Pydev Version: 1.3.12

Ok, after checking my error log, eclipse suddenly decided to recognize
the library.
I have no idea how or why, after having saved/restarted the application many
times etc.
So I guess now I'm good to go. Thanks for the extremely speedy response.

Just for future reference, any ideas as to what this may have been caused by?
Also, where is this forced builtin you mentioned? Is it the same thing as the
pythonpath?

Check http://fabioz.com/pydev/manual_101_interpreter.html for details on forced
builtins (and how to properly configure your pythonpath)

The usual problem in that is a misconfiguration on the pythonpath or a blocking
firewall to the shell that actually gets the tokens.

Cheers,

Fabio
