Why does Overriding QuickWidget::mousePressEvent fail to pass mouse events to the parent widget?

[mirro]

class cusQQuickWidget:public QuickWidget{
Q_OBJECT
public:
     cusQQuickWidget(QWidget* parent = nullptr):QuickWidget(parent){}
     virtual ~cusQQuickWidget(){}
protected:
     void mousePressEvent(QMouseEvent* p)
     {
             if (this->parentWidget())
                 {
             
                     //this->setAttribute(Qt::WA_TransparentForMouseEvents, true);
             
                     QPoint pt = this->mapTo(this->parentWidget(), e->pos());
             
                     QWidget *w = this->parentWidget()->childAt(pt);
             
                     if (w)   
                     {
             
                         pt = w->mapFrom(this->parentWidget(), pt);
             
                         QMouseEvent *event = new QMouseEvent(e->type(), pt, e->button(), e->buttons(), e->modifiers());
             
                         QApplication::postEvent(w, event);
             
                     }
                     //this->setAttribute(Qt::WA_TransparentForMouseEvents, false);
             
                 }
      }
};

Hi
By parent widget, you mean the Mainwindow/where the QuickWidget is placed ?

You seem to try to forward a an event.

But it makes little sense to me as I dont understand what you could use that for.

Do you try to know in MainWindow if QuickWidget was clicked ?
