Description
One very handy feature that many design software have is the ability to use simple math expressions in size and position controls fields.
For instance, if you have an item with a height of x, and you want to double it's height, you would be able to simply type after the x value '* 2' and press enter. The control would solve the math expression and set the new value. The same could be done with +, - , / and even %

There is an ongoing contract (a swiss province and Nyall Dawson) that will implement expression support for page resizing in Atlas serial printing.
This is kind of similar to your request - but slightly different. I guess you need just a temporary expression to calculate stuff, not in the atlas printing context.

Yeah - that's what I'm thinking. A temporary expression which evaluates once and then updates the text box with the evaluated value.

I had the feeling that this was done already. Am I wrong?

Not completely - there's still some widgets which use line edits instead of spin boxes and I'd like to allow math in these too

Any changes on this? Are there still widgets not allowing math?
I wouldn't mind help on that.
