I just downloaded wxPython, and was running some of the sample programs from here. However, on every line that uses a variable from wx.*, I get a \"Undefined variable from i

Answer 1

PyDev finds the references when you setup the interpreter in

Window -> Preferences -> Pydev -> Interpreter - Python

If wxPython was not in your site-packages directory when you first setup the interpreter, then the references to the wx objects and names will not be known to the editor lookup function. To fix this, remove the interpreter from

Window -> Preferences -> Pydev -> Interpreter - Python

and then select new. Re-add the python installation again and press apply. At this time, Pydev will import all of the site-package objects again and should populate the lookup dictionary. You'll want to restart Eclipse for changes to take place.
