Subject: More tk stuff

OK, I dug up an answer to my previous question; here's code to  
implement a window with scrollbars:

require 'tk'

root = TkRoot.new() { title "(Sc)rolling, (sc)rolling),  
(sc)rolling..." }
xbar = TkScrollbar.new(root, 'orient'=>'h').pack('side'=>'bottom',  
'fill'=>'x')
ybar = TkScrollbar.new(root, 'orient'=>'v').pack('side'=>'right',  
'fill'=>'y')
text = TkText.new(root, 'wrap'=>'none',  
'width'=>20).pack('fill'=>'both', 'expand'=>true)
text.insert('end', "A string that is longer than fits on one line...")
xbar.command(proc {|*args| text.xview(*args)})
text.xscrollcommand(proc {|first, last| xbar.set(first, last)})
ybar.command(proc {|*args| text.yview(*args)})
text.yscrollcommand(proc {|first, last| ybar.set(first, last)})

Tk.mainloop


Next question; how does one access the new 'themed' widgets in the  
modern releases of Tk? Something like ttk::entry, I mean; I assume the  
double colon wouldn't be used in Ruby (and I certainly couldn't get it  
to work.)

Thanks,
Ken
