QML load file.qml and scale

[TMJJ001]

Dear,

I want to make a resizable application. Until now I was able to make everything resizable.
Now for the following I need some support.

By a push of a button, I will load a new QML file in my "workspace".
I created a LMB_Main.qml were I have 3 images.

When I load the LMB.qml file, it doesn't fit the workspace.
How can I rescale this LMB_Main to make it fit the workspace?

 Item {
            id: workspace
            x: 0
            y: 0
            Layout.fillHeight: true
            Layout.fillWidth: true

            Loader {
                id: pageloader
                anchors.centerIn: parent
                //anchors.fill: parent
                source: "LMB_Main.qml"
            }

        }

Thanks in advance,
Kind regards,
TMJJ
