Math?

Is it possible to create a spinbutton where you can do some basic math (add, subtract, multiply, divide)? Such as say the box currently has a value of 6.500, I would like to be able to move the cursor to the end of the number, type +1.125, press enter and have the value of the box change to 7.625. Another example would be inputting fractional measurements such as 10+11/16, press enter and the value would show 10.6875.

That would require a math parser behind it = a lot of code.

no it would not: lmgtfy.com/?q=python+eval+math+expression

Ok, my C experience blinded my sight.

Yes, you can do that in the Python handler. I think Andy has done that on one of his GUI's. I've done it in Python. IIRC you use the activate signal to call your handler. I'll see if I can find an example.

Thanks John,

Looking forward to seeing an example.
