ComboBox list pass to Qt

[Damian7546]

Hi,
How can I call this function systemController.speedPrinting === selectedItemFromComboBox depending on select item from below combobox ?

ColumnLayout {
        id: stacViewCombobox1
        width: 500
        anchors {
            left: parent.left
            leftMargin: 30
            top: textSettingPrinter.bottom
            topMargin: 30
        }
        ComboBox {
            id: mycombo
            Layout.fillWidth: true
            font.pointSize: 16
             popup.modal: true
            model: ListModel {
                ListElement {
                    text: "HIGH SPEED (162,5 mm/sec)"
                    
                }
                ListElement {
                    text: "MEDIUM 1 SPEED (130 mm/sec)"
                }
                ListElement {
                    text: "MEDIUM 2 SPEED (97,5 mm/sec)"
                }
                ListElement {
                    text: "LOW SPEED (56 mm/sec)"
                }
            }
        }
    }

The better way would be to use the textRole, valueRole and currentValue properties of ComboBox

model: ListModel {
    ListElement {
        text: "HIGH SPEED (162,5 mm/sec)"
        speed: 162.5 // or 4 or an enum or whatever
    }
    // ...
}
textRole: "text"
valueRole: "speed"
onActivated: systemController.speedPrinting = currentValue

@Damian7546
provide a value for your List Elements
Provide an id to your model (listModelId)
Connect to onActivated(index) from combo box
This should provide the index in the model you need to call your function
setSpeed(listModelId.at(index).value)
