How to correctly override mousePressEvent in qquickwindow?

Question

I have an object inherited from qquickwindow with an overridden mousePressEvent method.

.h

class FWindow : public QQuickWindow
{
    Q_OBJECT

public:
    FWindow(QQuickWindow* parent = Q_NULLPTR);

protected:
    virtual void mousePressEvent(QMouseEvent* event) override;
};

.cpp

void FWindow::mousePressEvent(QMouseEvent* event)
{
    if (event->button() == Qt::LeftButton)
    {
        ...
    }
    QQuickWindow::mousePressEvent(event);
}

The problem is that when I add a Rectangle with MouseArea to a qml file, it does not react in any way. The signal goes to FWindow , not MouseArea . How to fix it?

.qml

FWindow
{
    visible: true;

    Rectangle
    {
        width: 50;
        height: 50;
        color: "green";

        anchors.verticalCenter: parent.verticalCenter;
        anchors.horizontalCenter: parent.horizontalCenter;

        MouseArea
        {
            anchors.fill: parent;

            onClicked:
            {
                console.log("clicked");
            }
        }
    }
}

该文档说默认情况下接受QQuickItem::mousePressEvent收到的QMouseEvent* event ，如果您不想接受它，则必须调用event->ignore() 。
