connecting C++ slot to signal from QML Component

[mzimmers]

Hi all -

On this page, there's a good description of connecting a QML signal to a C++ slot, providing that the QML component is created within C++. I need to connect a C++ slot to a signal coming from a QML object that isn't defined by the C++ class with the slot.

Here's a snippet of my QML:

GridView {
    id: equipmentView

    // the model selection is complex, but it works.
    model: (zoneModel.listSize() > 0)
           ? (zoneSelected === 0)
             ? equipmentModel.uuidList
             : (zoneSelected > 0 && zoneModel.listSize() > zoneSelected)
               ? zoneModel.getZone(zoneSelected).equipmentList
               : null
           : null

    delegate: Item {
        id: card
        property string uuid: equipmentModel.getEquipmentItem(model.modelData).uuid()
        signal switchClicked(string uuid, bool on)

        Switch {
            id: onOffSwitch
            onClicked: {
                card.switchClicked(card.uuid, onOffSwitch.checked)
            }
        }
    }
}

Is it possible to connect this signal to a C++ slot, or do I need to create this QML entity from with C++ in order to do so?

Thanks...

@mzimmers Do you know which c++ object you want to connect to?

Can't you do: onSwitchClicked: (uuid, on) => cppObject.activateEquipment(uuid, on)?

@GrecKo yes I know which C++ object (it's the instantiation of my EquipmentModel, of which there will be only one). So...how do I represent the C++ object in the QML?

And, not that it would be a problem, but...is your example a signal/slot usage, or are you just calling a C++ method?

EDIT: holy cow...it actually works!

onSwitchClicked: (uuid, onOff) => {
                     equipmentModel.receiveQmlSignal(uuid, onOff)
                 }

I didn't realize you could do that. Wow...mind blown.

Thanks, @GrecKo.
