Assigning an id in the delegate component

[Idodoqdo]

Hello, I want to set the id of the elements that are in delegate, so that later I can access the button signals in Timer. Please tell me how to do this

    Timer {
        interval: 20
        running: zoomminus.pressed || zoomplus.pressed || focusfar.pressed || focusnear.pressed // buttons id
        repeat: true
        onTriggered: {

            if (zoomminus.pressed) {
                nit300.upperFOV()
            } else if (zoomplus.pressed) {
                nit300.lowerFOV()
            } else if (focusfar.pressed) {
                nit300.focus++;
            } else if (focusnear.pressed) {
                nit300.focus--;
            }
        }
    }


    //    Connections {
    //        target: nit300


    //    }

    GridView {
        id:grid
        anchors.fill: parent

        property var actions: {
            "Фокус Far" : function () {print("far")}, //todo;
            "Фокус Near" : function () {print("Near")}, //todo;
            "Автофокус" : function () {nit300.focusAuto()},
            "Зум+" : function () {print("Зум+")}, //todo;
            "Зум-" : function () {print("Зум-")}, //todo;
            "E-Zoom 2X" : function () {nit300.eZoomX2()},
            "Время интегрирования+" : function () {nit300.upperIntegralTime()},

            "DDE++" : function () {nit300.edgeSharpenFast(true)},
            "Self Check" : function () {nit300.testImage()},

        }

Not supposed to this as delegates objects will be dynamically constructed & deleted. You should solve your problem in another way.

@dheerendra can you please suggest a way to react to the signal of one of the elements in the ListView?

[dheerendra]

@Idodoqdo

function callMe(){
}

Inside the delegate add the code. add Identity property of delegate as myId.

Component.onCompleted :{
myId.signal.connect(callMe);
}

@dheerendra Okay, but I need to handle pressing only certain buttons. Please tell me. I'll try on Monday, thanks
