Access navigation pane from stacked page

Question

I'm new to Blackberry Cascades and I want to create a simple NavigationPane. I'm very used to Qt's StackView which allouse you to push and pop pages to and from the stack. However, Qt's [StackView][1] has this attached property called Stack.view which allows you to access the stack from any child page.

How can I do this in Blackberry's Cascades? Is it possible to access the NavigationPane stack of pages from the current page you're in? I see this extremely useful.

For example I have this simple project with two qml files each representing one page:

Main page:

// main.qml
import bb.cascades 1.4
NavigationPane {
    id: nav
    Page {
        Container {
            ListView {
                dataModel: XmlDataModel {
                    source: "data.xml"
                }
                onTriggered: {

                    if (indexPath.length > 1) {
                        var chosenItem = dataModel.data(indexPath);
                        var contentpage = itemPageDefinition.createObject();

                        contentpage.itemPageTitle = chosenItem.name
                        nav.push(contentpage);
                    }
                }
                accessibility.name: "Listing"
            }

        }

    }
    attachedObjects: [
        ComponentDefinition {
            id: itemPageDefinition
            source: "ItemPage.qml"
        }
    ]
    onPopTransitionEnded: {
        page.destroy();
    }
}

Secondary page:

// ItemPage.qml
import bb.cascades 1.4

Page {
    property alias itemPageTitle: titlebar.title

    titleBar: TitleBar {
        id: titlebar
    }

    content: Container {
    }
}

Is it possible to access nav or NavigationPane from ItemPage.qml? I would like e.g. to create a new page from ItemPage.qml and push it on the stack. Is it possible to do so?

EDIT:

For example there is this documentation page on the Blackberry developers website which has this example with a main page:

and a secondary page:

As you can see, in the secondary myPage.qml he uses the navigationPane. How is that possible? How does he have access to an ID present in another component?
