add avatar stackview with filedialog

[filipdns]

Hello, I did project using stackview and I'm happy about the result.

In my first page I have 2 picture and selected one of them call the second corresponding.
here the code:

ListView {
            id: listView2
            anchors.fill: parent
            topMargin: 10
            leftMargin: 10
            bottomMargin: 10
            rightMargin: 5
            spacing: 20
            model: ["F-GMGB","F-GMLT"]
            delegate: ItemDelegate {
            width: avatar2.implicitWidth
            height: avatar2.implicitHeight
            rightPadding: avatar2.implicitWidth
            onClicked: stackView.push("qrc:/presentation.qml", { inConversationWith: modelData })
                Image {
                id: avatar2
                source: "qrc:/images/" + modelData.replace(" ", "_") + ".png"
                }
            }
        }

as you see, I have use 2 "model" named F-GMGB and F-GMLT.

Now I want to be able to add an other one to be able to update without recompile my project.

I try that:

ListView {
            id: listView2
            anchors.fill: parent
            topMargin: 10
            leftMargin: 10
            bottomMargin: 10
            rightMargin: 5
            spacing: 20
            model: ["F-GMGB","F-GMLT",filename]
            delegate: ItemDelegate {
            width: avatar2.implicitWidth
            height: avatar2.implicitHeight
            rightPadding: avatar2.implicitWidth
            onClicked: stackView.push("qrc:/presentation.qml", { inConversationWith: modelData })
                Image {
                id: avatar2
                source: "qrc:/images/" + modelData.replace(" ", "_") + ".png"
                }
            }
        }
    }
    Button {
        id: dialogButton
        text: "new"

        onClicked: {
            fileDialog.open()
        }
    }
    function basename(str)
    {
        return (str.slice(str.lastIndexOf("/")+1))

    }
    FileDialog {
        id: fileDialog
        title: "Please choose a file"
        folder: shortcuts.home
        nameFilters: [ "Image files (*.png)"]
        onAccepted: {

            var res1 = basename(fileUrl.toString())
            var res2 = res1.split(".")
            var filename = res2[0];
            console.log(filename)
            fileDialog.close()
        }
    }
}

so the filename is corrected extract but how can I implement the corresponding qml page and the qml.qrc to have it in memory on next opening?

Thank you for your help
