Anyone know how to change the color of the Tk progress bar? Everything  
I try just ends up with:

/usr/lib/ruby/1.8/tk.rb:2762:in `\_\_invoke’: unknown option “-colors”

But all the documentation stats that it does have a colors option:

> **[Ruby/TK - ProgressBar Widget](http://www.tutorialspoint.com/ruby/ruby_tk_progressbar.htm)**
>
> Ruby TK ProgressBar Widget - A ProgressBar provides a widget, which will show a graphical representation of a value, given maximum and minimum reference values.

Thanks,  
Sam

Supported options depends on your version of BWidget libraries.  
Probably, your progressbar widget is old and doesn’t support  
‘colors’ option.  
You can check supported options and status of a widget by ‘configinfo’  
method or ‘current\_configinfo’ method.  
If your progressbar widget is one of an old version, ‘foreground’  
option can change its bar color.

Yes the foreground option worked. Thank you
