动态创建的子qml,父qml如何获得子qml的信号

aa.qml

import QtQuick 2.4
Rectangle{
id:aa
height: 480
width: 640
color:"red"

MouseArea {
anchors.fill: parent
onClicked:{
var object=Qt.createComponent("bb.qml").createObject(parent);
}
}
//onSend: console.log("bb.qml Send clicked")//在这里捕捉 bb.qml 里 signal send() 信号

}

//------------------------
bb.qml

Rectangle {
id: bb
anchors.fill: parent

color: "red"
signal send()

MouseArea {
id: mousearea
anchors.fill: parent
onClicked:{
displayShow.destroy();
}
Component.onCompleted: {
mousearea.clicked.connect(send)
}
}

}

var object = Qt.createComponent("bb.qml").createObject(parent);

object.send.connect(yourSlotFunc);
