【Qt6】 MouseArea鼠标穿透

mouse.accepted : 控制合成事件和基本事件的传递

propagateComposedEvents 是控制合成事件在组件间的传递穿透

Window {
    id: window
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")
    color: "gray"

    Rectangle{
        height: 100
        width: 100
        anchors.centerIn: parent
        MouseArea{
            anchors.fill: parent

            onPressed: {
                console.log("press A")
            }

            onClicked: {
                console.log("click A")

        anchors.centerIn: parent
        MouseArea{
            anchors.fill: parent

            onPressed: {
                console.log("press B")
                mouse.accepted = false // 穿透，基本事件不受propagateComposedEvents影响
            }

            onClicked: {
                console.log("click B")
                mouse.accepted = false // 合成事件穿透
            }

            // 对于所有基本事件(pressed)，mouse.accepted = false ，事件未被接受，则继续按照视觉或堆栈顺序向下传递
            // 对于合成事件（clicked）,除了mouse.accepted，propagateComposedEvents也会拦截传递行为
            propagateComposedEvents: true // 合成事件可以穿透组件层
        }
    }
