Can anyone tell me if the TkListbox option  
insertBackground is available in Ruby Tk?

I’m having no luck when trying to set this option via  
the TkListbox.configure(‘insertBackground’, ‘red’)  
method or even trying to set this option through the  
TkListbox.new constructor.

What I’m trying to do is change the background color  
of a particular Listbox item.

Thanks in advance,

Jason T

If Tcl/Tk8.4.12’s man page about listbox is right,  
listbox widgets don’t have ‘-insertbackground’ option.
