QIntValidator input

[chaos_theory]

Hi there
I'm not sure if it's something's wrong with QIntValidator class, or with my code. I use this class as below:

QIntValidator *gV = new QIntValidator(0, 500, this);
gravityEdit = new QLineEdit(QString("%1").arg(parentWindow->scene->gravityForce.g), this);
gravityEdit->setValidator(gV);

QIntValidator *gV = new QIntValidator(0, 500, this);
gravityEdit = new QLineEdit(QString("%1").arg(parentWindow->scene->gravityForce.g), this);
gravityEdit->setValidator(gV);

To copy to clipboard, switch view to plain text mode 

Now when I launch the application and edit 'gravityEdit', validator works, but it accepts input from 0 to 999. Any ideas when did I go wrong? It looks like it sets input range maximum to powers of 10 only, but i want it to be 0 - 500, is it possible?

What happens after you leave the field or press return after typing in "999"?

QSpinBox would make it simple. It's basically a specialized line edit designed especially for numerical input.

Everything works like it was an accetable input...the value is just set to "999", like there was no validator :/

You're right, I thought about using QSpinBox , but i'm just curious is it bug in QIntValidator, or just my mistake

Ok, problem solved. My mistake was that I didn't use hasAcceptableInput() function to check if the input is Acceptable, before making any changes. Using validate() function to check the states of validator shows that for 500-999 it's Intermediate, that's why it was possible to enter that values from that range. And without a "guard" like hasAcceptableInput(), this input could be passed by textEdited(const QString &) signal.
