You can use the option, if your Tcl/Tk library, 
which is linked to Ruby, supports the option. :-)
Check Tk::TK_VERSION . 
It is a version of yoru Tk which works on Ruby/Tk. 
For example, Tcl/Tk8.0 doesn't have the option. 
So, Ruby/Tk which uses Tcl/Tk8.0 cannot use the option.

If new features of new Tcl/Tk are such new keys only, 
probably Ruby/Tk with new Tcl/Tk can support the option. 
If add new widgets, we need new class definition to use 
the widgets properly. 
Of course, if you use Tk.tk_call(...), 
there are no feature that cannot be controlled by Ruby/Tk.

Is '-state' option supported on Tcl/Tk8.4 ?
I heard there are some troubles to use Tcl/Tk8.4k for Ruby/Tk. 
I'm sorry but now I have no time to check and fix the troubles.
