Hi, I am using Perl/Tk to build a gui application and i need some advice. my issue is that i want to use a check-button in three states, i.e. i want to have a partial selection mode for check-button. But tk provide check-button with only two states.

Now with each check-button there is a variable associated on changing the value for that variable reflects the change in the corresponding check-button. What i want to do is alter this part of in such way that this variable can operate on three values rather than two(current behavior). What i mean is that instead of just having two values associated to that variable , i want to associate a third value in which i will change the select color property. Can this be done???
