I see.  I've only tried it on Windows and, bar a few quirks, it's quite 
good - a million times better than Tk on Windows at least.  Take, for 
example, the list box.  Under Ruby/Tk, the list box is essentially a 
text box with a list of items - one per line, and clicking a line 
selects that whole line.  You can't tap a key to go to an item beginning 
with that letter (you can in FxRuby), and scollbars have to be manually 
attached to a host control.  But, oh, they can't just be connected, no, 
that would be too simple.  They have to be put on the form as a seperate 
control.  But then you have to think about how that scrollbar docks to 
the side of the listbox, so a frame is needed to make sure the controls 
line up correctly, and then you have to tell it to act as a scrollbar 
for the listbox, and also tell it to change the size of the thumb based 
on the contents of the listbox.

I didn't even attempt to build a tree.  I ported my Rake dependency tool 
to FxRuby, and found it ridiculously easy to build a dialog with a 
couple of trees which do the job of the Tk version far better.  It has a 
file browse dialog (which the Tk version didn't) to load the rakefile, 
and even a search capability.

And not to mention the fact that it just looks better - it looks more 
like a Windows app, which is good on Windows.
