Thank you for this ! I use TWL all the time when testing my new Themes ! TWL works much better than twf (IMO)It has a nice easy to use GUI and the update installs over the existing install !! GREAT !! Thanks again !!

I made a mistake when I packaged it. I'll upload the corrected .debs soon but in the meantime you can just "sudo apt-get install python-metacity" and it will work.

One thing I never liked with TWF is that the scrollbars (or sliders, or whatever-you-wish-to-call-them) take up the entire slot, and there's no way to preview the groove below them, or how the buttons behave when the slider is all the way top or bottom.

Also, I usually have to install a theme in order to see how it works with the gnome panel. Will the theme look stupid with vertical panels? ...with panels taller than 24 px?

Can you address these in Widget Laboratory?

Speaking of the gnome panel, there's also the problem that with some themes, any buttons, menus, or other objects on the panel will not recognize the change when the panel background is set to use a solid color or a pixmap. The result is usually blank parts of the panel with the user settings, and items on the panel using the theme's background regardless of user settings. Any way this could allow people to preview that? Inconsistencies on the panel is the most common reason I choose to not use some themes.

I don't think I can make TWF preview gnome-panel, but the suggestion about scrollbars is a good one and I'll fix that.

I already saw that bug report, but it doesn't help me, because there is no workaround there.

Any thoughts?

I have just formatted my notebook and installed Fedora 12 i686, and after installing gnome-libs, gnome-python2-metacity and dbus-libs it works also for me...but in my PC with Fedora 12 x86_64 the dbus problem persist.

Thanks for your time,

Isn't this exactly like The Widget Factory?

No. The Widget Factory only previews Gtk themes and this previews both Gtk and Metacity themes.

Also, to update the preview in the Widget Factory (ie you made some changes to the gtkrc) you have to select a different theme and then re-select the theme you were editing. This monitors the *rc files and updates automatically. Also you can load any .glade file to preview on.
