How to send value from model to delegate which is separate file?

[milan]

hello, I have troubles sending value from a GridView model to a delegate. I have delegate in a separate file because I would like to have some enhancement. I have remove some code to make code compact for viewing. The model is C++ model

    GridView {
        width: parent.width
        height: parent.height
        cellHeight: 250
        cellWidth: 250
        id: appGrid
        model: chmodel
        delegate: GaugeComponent{
        }

// GaugeComponent
Item {
	function parseStrtoInt(str)
	{
		console.log("gauge string:"+str);
		console.log("gauge float:"+parseFloat(str));
		return parseFloat(str);
	}
	property real gaugevalue: parseStrtoInt(num) // num is data in the model

	CircularGauge {
		value: gaugevalue
		anchors.centerIn: parent.Center
		style: CircularGaugeStyle {
			needle: Rectangle {
				y: outerRadius * 0.15
				implicitWidth: outerRadius * 0.03
				implicitHeight: outerRadius * 0.9
				antialiasing: true
				color: Qt.rgba(0.66, 0.3, 0, 1)
			}
			tickmark: Rectangle {
				visible: styleData.value < 80 || styleData.value % 10 == 0
				implicitWidth: outerRadius * 0.02
				antialiasing: true
				implicitHeight: outerRadius * 0.06
				color: styleData.value >= 80 ? "#e34c22" : "#e5e5e5"
			}
			minorTickmark: Rectangle {
				visible: styleData.value < 80
				implicitWidth: outerRadius * 0.01
				antialiasing: true
				implicitHeight: outerRadius * 0.03
				color: "#e5e5e5"
			}

			tickmarkLabel:  Text {
				font.pixelSize: Math.max(6, outerRadius * 0.1)
				text: styleData.value
				color: styleData.value >= 80 ? "#e34c22" : "#e5e5e5"
				antialiasing: true
			}
			foreground: Item {
				Rectangle {
					width: outerRadius * 0.2
					height: width
					radius: width / 2
					color: "#e5e5e5"
					anchors.centerIn: parent
				}
			}
		}
    }
}

@milan I assume num is not available? Try giving your delegate an id and accessing the model through the Gridview.view.model attached property.

// GuageComponent
Item {
  id: mydelegate
  property real gaugevalue: parseStrtoFloat(mydelegate.GridView.view.model.num)
  ...
}

Your program should work without any issue. Please confirm whether model has property call 'num'. If it exist it should work.

What is not working ? What is the error you see ?
