[SOLVED]Signal from dynamic component to the page where it is created

[pizarro84]

Hi,

 QML newbie here. I made a timer that generates dynamic components in QML. I need help in changing values from the page (where the component was created) whenever I interact with those components (ex: clicking the dynamic component changes a variable value/component property in the page where it was created), something like signals and slots. How do I do this? Thanks in advance!

Im not sure if this will help you, but :

@
import QtQuick 1.0

Rectangle {
id: rect
width: 360
height: 360
property string my_text: "hello world"

Text {
    id: textBox
    anchors.centerIn: parent
    text: rect.my_text
}
MouseArea {
    id: mouseArea
    anchors.fill: parent
    onClicked: { textBox.color = "blue"; rect.my_text = "goodbye world" }
}
states: State {
   name: "change color"; when: mouseArea.pressed
   PropertyChanges { target: rect; color: "blue"; }
}

}

Thanks for the reply, actually my problem is that my dynamic component is on another QML file..

@Page {
id: splashscreen
rotation: 0

Rectangle {
    id:rect
    color: "#d3ff20"
    anchors.fill: parent
    Rectangle {
        id: house
        width: 80; height: 80
        color: "#00000000"
        x: 280
        y: 245
        Image {
            id: name
            source: "images/evernote.png"
            anchors.fill: parent
        }
    }

    ProgressBar {
        width: 200
        height: 50
        x: 220; y:310
        maximumValue: 100
        minimumValue: 0
        value: 100
        MouseArea {
            anchors.fill: parent

        }
    }

    Timer {
        interval: 800
        running: true
        repeat:  true


        onTriggered: {
            if (Qty.currentAliensCount < 10)
            {
                createItem(Math.floor(Math.random()*10000)T0,
                           Math.floor(Math.random()*10000)$0)
                Qty.currentAliensCount += 1;
            }
        }

    }


}


function createItem(mx,my)
{
    //the dynamic component from a separate qml..
    var component = Qt.createComponent("TestItem1.qml"); 
    var sprite = component.createObject(splashscreen,{"x": mx,"y":my});
}

}@

And I need to access the properties of components on this page whenever I click the TestItem1 dynamic component

I removed the javascript and created properties instead :)
