Which Linux distro are you using? Regardless, if you want a visual editor for wxPython, I'd suggest
wxGlade. It generates nice code but it may take a little getting used to using. I mostly just code all my GUIs by hand anyways.
As for good wxPython resources, here's some:
Style Guide - Not too comprehensive, but might offer some standardizing tips.
wxPython by Example - A short tutorial which has good examples for bare-bones apps.
wxPython Cookbook - Contains a lot of information on various aspects of wxPython. Lots of examples.
Widget Examples - Has a number of good application skeletons and examples about individual widgets and their uses.
Documentation - The regular documentation for wxPython.
VERY GOOD Tutorial - I'd recommend giving this a read through and looking at the example code as it's quite large and it covers a lot in an understandable way.
wxGlade Tutorial - If you decide to give wxGlade a go. Make sure to learn pure wxPython coding first so that you can do it by hand. Then use this for large GUIs just to speed things up if you want.
There was another
very definitive page with all the widgets and examples and information about them, but I can't seem to find it at the moment. I'll post it later if I do find it. Hope these help for now!
