Gnome to Wine color scraper

Readme.txt

This is a Python script to extract GNOME/GTK's color scheme and apply it to Wine, so that the themes (approximately) match.

Instructions:
1. Set your Gnome theme as you would like it
2. Run with a command like "python wine_colors_from_gtk.py"
3. Restart any apps running in Wine.  They should match the Gnome theme colors now.

Better description with screenshots here: http://www.endolith.com/wordpress/2008/08/03/wine-colors/

This is also stored on https://code.launchpad.net/~endolith/+junk/wine-color-scraper
Just trying out gist.github.com...


To do:

* Needs to separate out scrapers for each GTK engine where necessary.  (Can't an interface for this just be built into the engines instead?)
* Copy Gnome fonts as well as colors.  (Not sure where Wine stores these settings.)
* Something would need to call this script every time the Gnome theme is changed.

Everything else is working for me.

wineconfig.py and winewrite.py scripts in Guidance package for KDE do the same things:

Similar code is built into Mozilla:

Will be integrated into Wine Doors? http://www.wine-doors.org/trac/changeset/1536


All of Wine's 31 possible user.reg color values
Asterisk * next to comment if I've found a value that works for most themes
Question mark ? next to comment if not sure or can't find anywhere to scrape from

Damn. I need this, but syntax complains:

I hope, you can do something about this ;)
Thanks!

@UltraBlackLinux

I don't use Linux anymore, so try one of the forks. That looks like a syntax error in gconf, though, not in my script. Wrong Python version?
