[Solved]QDialog::eventFilter() can't Filter

[Corpse0327]

Hi all

I want to get rid of QDialog closing when Escape is pressed. So i used eventFilter() like this:

class ChangeMaster : public QDialog
{
protected:
    bool eventFilter(QObject *object, QEvent *event) override;
....
}

and in the source file

bool ChangeMaster::eventFilter(QObject *object, QEvent *event)
{
    qDebug() << "EventFilter entered";
   if(object == this && event->type() == QEvent::KeyPress)
    {
        qDebug() << "Event is key press";
        QKeyEvent * keyEvent = static_cast<QKeyEvent*>(event);
        if(keyEvent->key() == Qt::Key_Escape)
            return true;
        else
            return false;
    }

    return object->parent()->eventFilter(object, event);
}

When i run the program and press ESC, it always closes. Also it seems eventFilter never runs because there is no qDebug printing saying "EventFilter entered".

I couldn't figure out why. Probably because i am not doing everything properly. How can i solve this?

Thanks in advance

Hi @Corpse0327
