         100
        height: 100
        color: "#0000FF"
        signal send()
        onSend:console.log("xxxx");
        MouseArea{
            id:mousea
            anchors.fill: parent
            onClicked:console.log("1111")

        }

        Component.onCompleted:{/**信号处理器**/
            mousea.clicked.connect(send)
        }
    }

main.qml

import QtQuick 2.9
import QtQuick.Window 2.2

Window {
    visible: true
     640
    height: 480
    title: qsTr("Hello World")

    Test{
        onSend:console.log("xxxx");
    }
}
