onClicked and onReleased is not working while onPressed and onDoubleClicked is working fine in MouseArea of ListView

Himanshu Rohilla

Hello Everyone,

I created a sample application. This application is loading a QMainWindow. I set a QGraphicsView as a central widget of QMainWindow. QGraphicsView'scene is adding a widget i.e. QQuickWidget. This QQuickWidget is loading a QML file.

This QML file loading a Rectangle QML type as a root. In Rectangle, I am showing a ListView which is showing some data. Model and delegate are declared in QML file.

Now problem is, I am unable to get onClicked event in MouseArea of ListView. onDoubleClicked event is working fine.

I want to get an onClicked event. Please help me to get this event. I don't know what is missing here.

Sample application source code is as follows :-

QML Source Code :-

import QtQuick 6.5
import QtQuick.Controls 6.5

Rectangle {
    id: root

    visible: true
    width: 400
    height: 300

    ListModel {
        id: model

        ListElement {
            name: "Bill Smith"
            number: "555 3264"
        }
        ListElement {
            name: "John Brown"
            number: "555 8426"
        }
        ListElement {
            name: "Sam Wise"
            number: "555 0473"
        }
    }

    ListView {
        id: patientList

        visible: true

        spacing: 15

        focus: true
        width: parent.width

        height: 100

        model: model

        delegate: Text {
                text: model.name + ": " + model.number
        }

        MouseArea {
            id: listViewMouseArea

            hoverEnabled: true
            anchors.fill: parent

            onClicked: {
                console.log("In onClicked MouseArea of ListView");
            }
            onDoubleClicked: {
                console.log("In doubleClicked MouseArea of ListView");
            }
        }
    }
}

    auto lObj = quick_item->rootObject();
    if (!lObj) {

    scene->addWidget(quick_item);


    QGraphicsView* view = new QGraphicsView(scene,this);
    view->setMouseTracking(true);
    view->resize(600, 400);
    view->setBackgroundBrush(Qt::yellow);
    view->show();

    setCentralWidget(view);
    resize(600,400);

    centralWidget()->show();

Thanks in advance :)
