[Qt-qml] QML connections.

[Rakesh.Mutharaju at tieto.com]

Hello,

I have 3 .qml files pageloader.qml (first file) , A.qml and B.qml. I emit signal from A and B on mouse action and which I am capturing in pageloader.

Both A and B have signals "signal aclicked()" and "signal bclicked()" which are connected to onAclicked() and onBclicked() signal handlers respectively implemented in pageloader.qml. Both the signals are working when other is commented. But are not received successively.

//pageloader.qml
import Qt 4.7
Item {
    width: 200
    height: 200
    Loader {
        id:load
        source: "A.qml"
        B{
            onBclicked:{
                load.item.opacity = 0
                console.log(load.source)
                load.source = ""
                console.log("B Clicked!")
                console.log("B unloaded status !"+load.status)
                load.source = "A.qml"
                console.log(load.source)
                console.log("A loaded status !"+load.status)
                load.item.opacity = 1
            }
        }
        A{
            onAclicked:{
                load.item.opacity = 0
                console.log(load.source)
                load.source = ""
                console.log("A Clicked!")
                console.log("A unloaded status !"+load.status)
                load.source = "B.qml"
                console.log(load.source)
                console.log("B loaded status !"+load.status)
                load.item.opacity = 1
            }
        }
    }
}

//A.qml
import Qt 4.7
Rectangle {
    id: rectangleA
    width: 200
    height: 200
    color: "#0000ff"
    signal aclicked()
    Text {
        x: 72
        y: 67
        width: 28
        height: 48
        text: "A"
        font.bold: true
        font.pointSize: 30
        anchors.horizontalCenter: parent.horizontalCenter
        anchors.verticalCenter: parent.verticalCenter
        MouseArea{
            //id: areaA
            anchors.bottomMargin: 0
            anchors.topMargin: 0
            anchors.leftMargin: 0
            anchors.rightMargin: 0
            anchors.fill: parent
            Connections {
                onClicked:{
                    console.log("A Clicked!")
                    rectangleA.aclicked()
                }
            }
        }
    }
}

//B.qml
import Qt 4.7
Rectangle {
    id: rectangleB
    width: 200
    height: 200
    color: "#ff0000"
    signal bclicked()
    Text {
        x: 72
        y: 67
        width: 28
        height: 48
        text: "B"
        font.bold: true
        font.pointSize: 30
        anchors.horizontalCenter: parent.horizontalCenter
        anchors.verticalCenter: parent.verticalCenter
        MouseArea{
            //id: areaB
            anchors.bottomMargin: 0
            anchors.topMargin: 0
            anchors.leftMargin: 0
            anchors.rightMargin: 0
            anchors.fill: parent
            Connections {
                onClicked:{
                    console.log("B Clicked!")
                    rectangleB.bclicked()
                }
            }
        }
    }
}

>From the debug log I notice that
A Clicked!

file:///Z:/test_trans/A.qml

A Clicked!

A unloaded status !0

file:///Z:/test_trans/B.qml

B loaded status !1

B Clicked! ---->>>>>> signal is lost

Could someone correct me?


Thanks and Regards,
Rakesh
