I tried to develop UI in QML. The development environment is embedded. This environment spends a lot of time to boot. So, Tries to use the following method with Loader element.

//Main.qml
@
Rectangle {
width: 800; height: 600; color:"blue"

Column{
    width: parent.width; height: parent.height
    Row{
        width:parent.width; height:parent.height*0.2
        Rectangle{
            id: runButton

            width: parent.width*0.2; height: parent.height*0.8
            color: "red"
            Text{
                text: "RUN";   color:"white";  font.pointSize: 20;    anchors.centerIn: parent
            }
            MouseArea{
                anchors.fill: parent
                onClicked: {
                    readyGO.source= "./test3.qml"
                }

            }
        }

        Rectangle{
            id: quitButton
            width: parent.width*0.2
            height: parent.height*0.8

            color: "green"

            Text{
                text: "Quit"
                color: "white"
                font.pointSize: 30
                anchors.centerIn: parent
            }
            MouseArea{
                anchors.fill: parent
                onClicked: {
                 testMain.source= ""
                }
            }
        }
    }
    Rectangle{
        width: parent.width*0.8
        height: parent.height*0.8

anchors.horizontalCenter: parent.horizontalCenter
Loader{
id: testMain
}
}
}
}

// test3.qml
Rectangle {
id: rect
width: 360
height: 360
Text {
anchors.centerIn: parent
text: "~~~~~~~~~~~~asfsdfas~~~" // changing contents -> "Hello"
}
}
@
and then, The contents of the file(test3.qml) have changed.
But, After fixing the contents of the file is not applied.

Could you tell men How to reload a changing qml File?
