Question

I’m developing a virtual musical keyboard that allows you to press keys on your keyboard and have it play notes. So in my MainWindow class I have reimplemented keyPressEvent. I would like to ignore events generated by modifiers (Control, Alt, Shift, etc.), as well as events generated by other non-character keys such as Tab, Backspace, and Enter. Something like this would be ideal:

void MainWindow::keyPressEvent(QKeyEvent *event)
{
    if (!event->key().isCharacter()))
    {
        event->ignore();
        return;
    }

    // handle the event
}

Is there a way to do something like that (short of testing every possible non-character key individually)? If not, is there at least a way to easily ignore the event if it is a modifier?

Answer 1

Looks like you want QKeyEvent::text().
