[Pyroxar]

I have Loader object which has id "pageLoader".
I load first "first.qml" and i need to change the page to other with the position first page but "pageLoader" is not visible.
What can i do that "pageLoader" make globally?

Thank you!

In main.qml file

import QtQuick 2.7
import QtQuick.Controls 2.0
import QtQuick.Layouts 1.0
import QtQuick.Window 2.2
import QtQuick.Layouts 1.3

ApplicationWindow {
    visible: true
    width: Screen.width
    height: Screen.height
    title: qsTr("Hello World")

    property Loader parentLoader: pageLoader
    Loader { id: pageLoader; anchors.fill: parent; source: "Hello.qml" }
}

and anywhere else:

Button {
                anchors.horizontalCenter: parent.horizontalCenter
                anchors.bottom: parent.bottom
                anchors.bottomMargin: 30
                width: 150
                text: "CLICK ME"
                onClicked: pageLoader.setSource("MyQMLFile.qml", {"parentLoader": pageLoader});
}

Is something like that what you want ?

Component {
   id: pageLoader
   Loader {
       ...
   }
}

loaderExample.qml

Add a property "parentLoader" (for example) to first.qml, then when using Loader.setSource pass your loader (by it's id) to "parentLoader" via second parameter of setSource. In first.qml address the loader via parentLoader property instead of id.

pageLoader.setSource("first.qml", {"parentLoader": pageLoader});
