keyPressEvent - "ctrl + tab" handle two time

[somename]

bool Widget::eventFilter(QObject *target, QEvent *event)
{
    QKeyEvent *keyEvent = static_cast<QKeyEvent*>(event);
    if (keyEvent->modifiers() == Qt::ControlModifier) {
        if (keyEvent->key() == Qt::Key_Tab) {
        qDebug() << "Handling..";
        return true;
        }
   return false;
   }
}

bool Widget::eventFilter(QObject *target, QEvent *event)
{
    QKeyEvent *keyEvent = static_cast<QKeyEvent*>(event);
    if (keyEvent->modifiers() == Qt::ControlModifier) {
        if (keyEvent->key() == Qt::Key_Tab) {
        qDebug() << "Handling..";
        return true;
        }
   return false;
   }
}

To copy to clipboard, switch view to plain text mode 

then I see that this handler called two time:

ApplicationOutput:
Handling..

did you hold the button, then see autoRepeatDelay, autoRepeatInterval.

No, I have no button

The ctrl and tab button (key)

KeyEvent records any sort of key event - both key press and key release. You're probably seeing the initial press followed by the subsequent release being processed here.

Check the Type of the event to see if it is KeyPress or KeyRelease, and only handle one of them.

Thanks! I have forgotten this!

and..
How to use auto repeat delay?

[Lykurg]

I never have dealt with such kind, but I would start with: QShortcut::autoRepeat.
