QML Connections: Cannot assign to non-existent property "onMessage" using Loader how to solve error

AexAcad

Hi,

I am currently trying to use a Loader in my main.qml to load a suggestions.qml file from the same directory I am following the Loader documentation but I am unable to get the connections working. I keep getting the error: Cannot assign to non-existent property "onMessage" and i can't find any info on how to solve this anywhere. Please help with some example or where am i making the error ?

Main.qml:

import QtQuick 2.0
import QtQuick.Controls 1.0
import QtQuick.Layouts 1.0
import Qt.WebSockets 1.0

Rectangle {
    id: rectangledisplaybox
    anchors.fill: parent

        Loader {
            id: suggestionswidgetloader
            anchors.fill: parent
            visible: true;
            source: "Suggestions.qml"
            active: true;
             focus: true;

             Connections {
                target: suggestionswidgetloader.item
                onMessage: console.log(msg)
                Component.onCompleted: print ("Connections Component.onCompleted")
             }

        }
}

My Suggestions.qml file:

import QtQuick 2.0

Item {
anchors.fill: parent

        Rectangle {
            id: suggestion1button
            width: 30
            height: 30
            signal message(string msg)
            anchors.top: parent.top
            anchors.topMargin: 30
            anchors.horizontalCenterOffset: -75
            anchors.horizontalCenter: parent.horizontalCenter
            border.color: "#1a4878"
            border.width: 1

            Component.onCompleted: {
                    print("Component.onCompleted")
                    suggestion1button.message("signal sent");
                }

            MouseArea {
                id: mouseArea1
                hoverEnabled: true
                anchors.fill: parent
                onClicked: suggestion1button.message("clicked!")
            }
        }
}

@AexAcad
the message signal is defined in a child item of the item you are loading, but not on the item you are loading and you are using in the Connections element

I have added the signal to my main item and I receive the console log:
qml: Component.onCompleted
qml: Connections Component.onCompleted

but when I click the mouse area in my rectangle within the loader no message is logged in onMessage: console.log(msg).

import QtQuick 2.0

Item {
anchors.fill: parent
signal message(string msg)

        Rectangle {
            id: suggestion1button
            width: 30
            height: 30
            signal message(string msg)
            anchors.top: parent.top
            anchors.topMargin: 30
            anchors.horizontalCenterOffset: -75
            anchors.horizontalCenter: parent.horizontalCenter
            border.color: "#1a4878"
            border.width: 1

            Component.onCompleted: {
                    print("Component.onCompleted")
                    suggestion1button.message("signal sent");
                }

            MouseArea {
                id: mouseArea1
                hoverEnabled: true
                anchors.fill: parent
                onClicked: suggestion1button.message("clicked!")
            }
        }
}

@AexAcad
now you have 2 items with a message signal.
You trigger the signal of the first, but connect to the signal of the second.

Item {
id: main

signal message(string msg)

        Rectangle {
            id: suggestion1button
           ...
            MouseArea {
                id: mouseArea1
                ...
                onClicked: main.message("clicked!")
            }
  ....
}
