Is there a way to distinguish whether this formula is correct or not?
For example
3*(20-10
I want to let you know that there's an error in this formula when you enter an equation without parentheses.
Is it possible to do engineering formulas as well as basic four-line operations? -
There is
isValid()method, but it won't tell you where and what the error is.BTW. Qt extended has been abandoned a long time ago.
