Catching Qt/C++ signal from QML custom Item/code - howto

[MarkoSan]

Consider the first argument to setContextProperty() as equivalent to a QML "id" of the object.
I think you've already done that with the model.

Ok, so there is no way to handle this via signal/slot, since this is what am I trying to do (this code does NOT work) - file UeStatusIndicator.qml, which is called from main.qml:

import QtQuick 2.0
 
import si.mikroelektronika 1.0
 
Item
{
    id: ueStatusIndicator
 
    property string ueParamImageStatusOn
    property string ueParamImageStatusOff
 
    signal ueSignalDatabaseConnectionChanged(UeTypeDatabaseConnectionStatus status) // from UeStatus
 
    state: "ueStatusIndicatorDabaseNotConnected"
 
    Image
    {
        id: ueStatusIndicatorCurrentImage
 
        smooth: true
 
        fillMode: Image.PreserveAspectFit
 
        width: 96
        height: 96
 
        sourceSize.width: 96
        sourceSize.height: 96
    }   // Image
 
    Connections
    {
        target: ueStatusIndicator
 
        onUeSignalDatabaseConnectionChanged:
        {
            state=(status===UeTypeDatabaseConnectionStatus.CONNECTED):
                   "ueStatusIndicatorDabaseConnected"?
                   "ueStatusIndicatorDabaseNotConnected"
        }
    }   // Connections
 
    states:
    [
        State
        {
            name: "ueStatusIndicatorDabaseConnected"
 
            PropertyChanges
            {
                target: ueStatusIndicatorCurrentImage
                source: ueParamImageStatusOn
            }   // PropertyChanges
        },  // State
 
        State
        {
            name: "ueStatusIndicatorDabaseNotConnected"
 
            PropertyChanges
            {
                target: ueStatusIndicatorCurrentImage
                source: ueParamImageStatusOff
