Qt tab order keys

A user can step through the widgets of QtGUI via key "Tab" or via arrow keys "<-" and "->".

Does anybody know how to disable the arrow keys for this purpose? I need the arrow keys for something else.

Solution

  • You would need to reimplement the corresponding event in your own QWidget subclass as follows:

    bool MyWidget::keyPressEvent(QKeyEvent *keyEvent)
{
    if (keyEvent->key() == Qt::Key_Left || keyEvent->key() == Qt::Key_Right) {
        // Do nothing
    } else {
        QWidget::keyPressEvent(keyEvent);
    }
}
