trying to access children property from a function defined in .js file

[ashajg]

hi guys

I have a function in .js file. I am invoking that function on mouse click event and trying to change color of rectangle.

.js function

function check(iCompID)
{
console.log("--------->"+iCompID)
parentID.children[iCompID].color="RED"
}

parentRectangle

Rectangle
{

    property string parentID: "mainrow"

    id:ventgrp
    width:800
    height:100
    color:"lightGray"
    anchors.bottom: parent.bottom
    Row
    {id:mainrow
    anchors.fill:parent
    }


    Component.onCompleted:
    {
    console.log("ventgrp created");
     ComponentCreator.createComponent();
    }


}

childRect

import QtQuick 2.0
import "qrc:/controller.js" as MoreSettingsCreation
Rectangle
{id:ventbtn
    width:200
    height:100
    color:"DarkGray"
    //anchors.left: parent.left
    border.color:"black"
      property int iCompID:0;
    Rectangle
    {
        id:vbutton
        height:40
        width:100
        anchors.centerIn: parent
        color:"lightgray"
        Text {anchors.centerIn: parent
            id:vbuttontext
            text: qsTr("Vent Mode")
        }

        MouseArea
        {
        anchors.fill:parent
        onClicked:{MoreSettingsCreation.createMoreSettingComp();
        MoreSettingsCreation.check(iCompID);
        }
        }
    }
}

ERROR:

qrc:/controller.js:102: TypeError: Cannot read property '0' of undefined code 0

problem is here it seems

parentID.children[iCompID].color="RED"

what is the problem ?

one more thing guys if I am using parentID it is throwing this error but if I am using mainrow its working fine ... this line is faulty I guess property string parentID: "mainrow"

any clue??

@ashajg Hi! I could see you have declared 'parentID' as string and trying to access it as QObject. Component id's are not string.

Changing to the following, should work for you

property string parentID: "mainrow"     --- > property alias parentID: mainrow

thanks a lot @Yashpal
