[pygtk] Min and max values of multiple spinbuttons

[Timo]

Hello, I have 3 spinbuttons in my program. What I want is that 
spinbutton 1 has always the lowest value and can not be more than 
spinbutton 2. Spinbutton 2 should always be between 1 and 3. And 
spinbvutton 3 should always have the biggest value.
So is there a way to stop spinbutton 1 when it reaches the vlaue (or 
value -1) of spinbutton 2 and so on?
