main.qml:

ApplicationWindow {
    id: mainWindow

    // here is where i need to get the TextFiled text set as "something"

    // Views (initialy used SwipeView)
    StackLayout {
        id: view
        anchors.fill: parent
        currentIndex: 0

        Item {
            id: view_InitialScreen
            InitialScreen {}
        }
        Item {
            id: view_ChoiseOffline
            ChoiseOffline {}
        }
    }
}

ChooseOffline.qml:

Rectangle {
    id: parentObject
    anchors.fill: parent

    Rectangle {
        id: testRect

        Rectangle {
            id: preselectedStrloRectangle

            Rectangle {
                id: scanRectangle

                Image {
                    id: scanImage
                }
            }

            Rectangle {
                id: preselectedStrloRectangle1

                Label {
                    id: preselectedStrloLabel1
                }
            }
            Rectangle {
                id: preselectedStrloRectangle2

                TextField {
                    id: preselectedStrloTextfield2
                    text: "something"
                }
            }
            Rectangle {
                id: preselectedStrloRectangle3

                Image {
                    id: clearImage
                }
            }
        }

        Rectangle {
            id: serialNumberRectangle

            Rectangle {
                id: serialNumberRectangle1

                Label {
                    id: serialNumberLabel1
                }
            }
            Rectangle {
                id: serialNumberRectangle2

                TextField {
                    id: serialNumberTextfield2
                }
            }
        }

	... and so on
}

so far the only way I was able to console.log() the text value is by:

console.log(view_ChoiseOffline.children[0].children[0].children[0].children[2].children[0].text)

but this is a terrible solution as Im keep adjuting the code, adding more childrens above and bellow so this would constantly change...

everytime i try to use IDs instead of children[int] i get an error that Cannot read property xxxx of undefined.
i have tried to use difenret id name instead of children[0], or simply children[parentObject]/children['parentObject'] or ucing "item" instead of "children".

so is there any way to access it simply by ID(s) out of the main.qml?
