    Default 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:
    Qt Code:
    1. QLineEdit::setMaxLength(3);
    To copy to clipboard, switch view to plain text mode

    Reimplement sizeHint().
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

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

    wysota:
    What can I do with sizeHint()?

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