QML alias not working

[Dolphin]

Anyone any ideas why this code is not working? I have a loader in main which is happily loading files the c++ spits out to it but a slightly different mechanics is required for the username/password and I thought an alias would be simpler than a signal/slot. The loader (Main.qml) has an alias which I am trying to use to go from the username to the password (Loggon_username.qml)

Main.qml

@
import QtQuick 2.0

Rectangle
{
id: window
property alias mainLoader: loader

Component.onCompleted:
{
    loader.forceActiveFocus()
}

Rectangle
{
    id: promptsContainer
    width: parent.width
    height: prompts.height * 1.25
    color: "#2A51A3"
    anchors.top: parent.top

    Text
    {
        id: prompts //text showing what voice is saying
        anchors.centerIn: parent
        color: "orange"
        font.pointSize: 20 //coreMenu.promptsFontPointSize
        width: parent.width * 0.9
        wrapMode: Text.WordWrap
        clip: true
    }
}

Loader
{
    id: loader
    height: window.height - promptsContainer.height
    anchors.left: parent.left
    anchors.right: parent.right
    anchors.bottom: parent.bottom
    visible: source != ""
    source: "Loggon_password.qml"
    onSourceChanged: console.log(loader.source);
 }

 Keys.onPressed:
 {
    QMLManager.handleKey(event.key)
    loader.source =  QMLManager.getLoaderSource()
    console.log(loader.source)
 }

}
@

Loggon_username.qml
@import QtQuick 2.0

Rectangle
{
anchors.fill: parent;

Component.onCompleted:
{

  // promptsBar.text = qsTr("Please enter your MTM username");
}
TextEntry
{
    title: QMLManager.getTitle();
    onTextEntered:
    {
        QMLManager.setUsername(text);
        Main.mainLoader.setSource("Loggon_password.qml")

       // Main.mainLoader.source = "Help.qml"
    }
}

}

"Main" is outside of scope in your Loggon_username. It won't work.

What do you mean by out of scope? The doc says this should work if the qml files are in same directory :-)

[sierdzio]

"Main" would need to be defined somewhere in Loggon_username.qml for it to be visible inside. Or maybe I misunderstood the situation.

• if I import "Main.qml" the file will not load at all (which means it thinks there is a syntax error I think)
• if main.qml file does not start with a capital when you type main.mainLoader it does not recognise it as a property
• if Main.qml starts with 'M', when you are in the username file typing "Main." the text changes colour and you get a list of properties including the mainLoader

I have tried this in a small test app and I get the same results
