[SOLVED] create object dimanically problem



  • I want to create dynamically qml objects, from another qml file with javascript. Problem: "that pressing a button on the newly created buttons rise to new text from Array (myCars[])".

    I want to do when i pressed the button named "Array" created new objects (buttons) has a different text from Array (MyCars[]).

    Thanks for any help. ;)

    These are files:

    My main.qml file:

    @import QtQuick 2.0
    import QtQuick.Controls 1.0
    import "componentCreation.js" as MyScript

    Rectangle {
    id: appWindow
    width: 300; height: 300

    Item {
        id: container
        width: 60; height: 400;
        anchors.horizontalCenter: parent.horizontalCenter;
    
        Text {
            id: spp;
        }
    }
    
    Button {
        text: "Array";
        opacity: 80;
        onClicked: {
            MyScript.createSpriteObjects();
        }
    }
    

    }@

    Sprite.qml (button created as object):

    @import QtQuick 2.0
    import "componentCreation.js" as MyScript

    Rectangle {
    id: button;
    anchors.horizontalCenter: parent.horizontalCenter;
    width: 50;
    height: 20;
    color: "green"

    MouseArea {
        anchors.fill: parent
        onClicked: {
            console.log("Clicked");
    
    
        }
    }
    

    }@

    Object create function "componentCreation.js":

    @function createSpriteObjects() {
    var component = Qt.createComponent("Sprite.qml");
    var myCars=new Array("A","B","C");
    var sprite;

    for (var i=0; i<myCars.length; i++) {
        sprite = component.createObject(container);
        sprite.y = (sprite.height + 15) * i;
        spp.text = myCars[i];
    }
    

    }@

    Hi,

    So far i have understood from your explanation is you want to set text (viz. "A","B" or "C") from Array inside the Sprite.qml from the "componentCreation.js"

    If that is the case the you need to declare an alias in Sprite.qml and then you can access that alias from the js.

    So add this in Sprite.qml at the top
    @
    property alias customtext: button.mytext
    property string mytext
    @

    then add a Text element in the same as,
    @
    Text {
    id: txt
    text: mytext
    }
    @

    then access the "customtext" property from js as,
    @
    sprite.customtext = myCars[i];
    @

    Hope this helps a little.
