How to limit the size of QLineEdit?

Hi,

I want to limit the size of QLineEdit to only 3 chars, how to do that?

Notice that the user can change the font of QLineEdit so I need it to resize to show only 3 chars in user selected font size?

Thanks,
Mohammad

Use:

Code:

---

QLineEdit::setMaxLength(3);

Reimplement sizeHint().

yogeshgokul:
setMaxLength() // Does not change the width of the QLineEdit

What can I do with sizeHint()?

Whatever you want. Look at the sourcecode for QLineEdit::sizeHint() and in the subclass adjust it accordingly.

Or read the documentation.
