I wrote an applet that makes an API call every 10 minutes, but I want it to show a message if the computer is offline. This means I need to get the network status within QML. I thought a DataEngine might be available, but there isn’t.

I read the code for plasma-nm and found this solution hack:

import org.kde.plasma.networkmanagement 0.2 as PlasmaNM
PlasmaNM.NetworkStatus {
    id: networkStatus
}
PlasmaComponents3.Label {
    visible: networkStatus.networkStatus != "Connected"
    text: i18n("Network disconnected")
}

But I think comparing strings is a terrible way because I don’t know what will happen in other locales.

Is there a better way?

    What about checking via dbus?

        I need to setup notifications here. I am not familiar with how qml works, but can’t ituse qt native integration, like the one documented in the kde page

    Did you try:

    import org.kde.plasma.networkmanagement 0.2 as PlasmaNM

PlasmaNM.NetworkStatus {
    id: networkStatus
}

PlasmaComponents3.Label {
    visible: networkStatus.connectivity !== PlasmaNM.NetworkManager.Full
    text: i18n("Network disconnected")
}

    This use an enum and should be a lot more robust

      It seems networkStatus doesn’t provide a connectivity attribute and PlasmaNM.NetworkManager doesn’t have a Full either:

      console.log(Object.keys(networkStatus))
qml: [objectName,activeConnections,networkStatus,objectNameChanged,activeConnectionsChanged,networkStatusChanged]

      networkStatus.connectivity !== PlasmaNM.NetworkManager.Full
.../contents/ui/main.qml:150: TypeError: Cannot read property 'Full' of undefined

    You should list the properties of the object you are dealing with. Perhaps there are some unknown functions/properties that may do what you want
