QQuickWidget embeded in QDialog has no hover effection at show

yanqinh

A. My trouble:
I embed a QQuickWidget into QDialog.
But the qml MouseArea of Button will have no hover effection after showing until I clicked any position (also desktop).

It would have hover effection if I replace dialog.exec() with dialog.show() or exec with WindowModality. ( I need ApplicationModality.)

B. What I have tried but no use:

I used to try giving focus to MouseArea in qml by Timer, calling forceActive() in cpp, setFocus() etc, and QcoreApplication::postEvent(MousePressEvent...).

C. My idea
I don't know how to solve it, maybe I will replace QDialog with QQuickView.

I use QQuickWidget in QDialog to reuse some cpp implementation ( frameless, shadow and corner with radius).

I’m hoping to hear your thoughts.

    WidgetQuickDialog dialog;
    dialog.SetContentText(text);
    dialog.exec();

import QtQuick
import QtQuick.Window
import QtQuick.Controls
import QtQuick.Layouts

Item {
    id: root

    property string btnRightText: "btnRightText"
    property string contentText: "contentText"

    signal signalBtnRightClicked

    anchors.fill: parent

    Rectangle {
        anchors.fill: parent
        color: "white"
    }
    ColumnLayout {
        anchors.fill: parent

        Text {
            Layout.fillWidth: true
            color: "#1C1F23"
            text: root.contentText

            font {
                family: "PingFang SC"
                pixelSize: 16
            }
        }
        Item {
            Layout.fillHeight: true
            Layout.fillWidth: true
        }
        Button {
            function getBgColor() {
                var normalColor = "#00C221";
                if (pressed) {
                    return Qt.darker(normalColor, 1.2);
                } else if (hovered) {
                    return Qt.darker(normalColor, 1.1);
                }
                return normalColor;
            }

                onPressed: function (mouse) {
                    mouse.accepted = false;
                }
            }
            /* Just a try, ths log will outputs but still no hover effection
            Timer {
                interval: 500
                repeat: false
                running: true

                onTriggered: {
                    console.log("hello world")
                    btnMouseArea.forceActiveFocus();
                    btnMouseArea.entered();
                    btnMouseArea
