<![CDATA[Send Signals between different Qml Objects]]>Hello,
I have some items define in different QML files and i load them dynamically base on user option in my main qml. I want when one of these items is clicked to load a specific item in my main QML file.
As i was searching for a solution for this i tried Signals but i can only make it work if items are defined in main QML. I think the problem lies in the way i initialize my QML items(i dont know if there is otherway around)

The code below is how i choose which Grid to load (the items are initialized there) base on user option

 function getModelFile()
    {
        if (choice === "1") return "Fourby4Mesh4VCs.qml";
        else if (choice === "2") return "Threeby3Mesh4Vcs.qml";


    }
Loader{
                width:rowLayout.width*0.55
                height: rowLayout.width*0.55
                anchors.left: topologyLayout.left
                anchors.top: topologyLayout.top
                sourceComponent: none.none
                id:loadTopology
                source:getModelFile()

            }

You are loading QML file through loader. This creates new object that representing that qml file. You can access the object creation loader through id:loadTopology.item.

You can define connections like this for the signals which are emitted from the qml files which are loaded through loader.

Connections {
target : loadTopology.item
on<Signal>:{

}
}

Please note it is not about signals between qml files. QML files are components. You are creating the objects from these components. Signals/slots communication need to happened between objects.

If you use Loader, did you follow "Receiving signals from loaded objects" in Loader doc?
