foxGUIb is an interactive gui builder for fxruby written entirely in Ruby.
It does not require much knowledge of the FXRuby API and therefore is 
also a good start for fxruby newbies. foxGUIb is a completely redesigned 
and rewritten version of the fox-tool project.

Check out the Project Wiki for details and documentation.

I have been using foxGUIb myself for a about a year at work before I 
prepared it for release to the public. I consider it especially useful 
because you can tweak your fxruby user interfaces interactively and that 
preserves a lot of time, fox-api reading and finger typing.
