QInputDialog::getInt() does not update state of Ok button when scrolling

Compile and start the attached project. The input dialog accepts integers from 1 to 100.

Now do the following steps to reproduce the problem:

1. Enter invalid number 0 -> Ok button gets disabled.

2. Use Up arrow to increase the entered value -> number is incremented to 1 -> Ok button gets enabled.

3. Enter invalid number 0 again -> Ok button gets disabled again.

4. Use mouse wheel to increase the value again -> Ok button stays disabled.

Maybe other static methods of QInputDialog are effected too.
