QML ListView draws ObjectModel outside of its bounds

问题

I'm trying to get into QT/QML coming from WPF/XAML.

In a test GUI, I'm using a ListView to display different Models on click of a button. This works alright so far, the view keeps showing each model when I click the corresponding button. But it still draws all the other models outside of its own bounds, overlapping surrounding elements with them. Can I turn this behaviour off?

This is my ListView:

ListView
{
    id: list_view

    anchors.fill:                   parent
    model:                          main_view_model
    snapMode:                       ListView.SnapOneItem
    boundsBehavior:                 Flickable.StopAtBounds
    highlightFollowsCurrentItem:    true
    highlightMoveDuration:          75
    highlightRangeMode:             ListView.StrictlyEnforceRange
    currentIndex:                   view_index
}

And this is the ObjectModel:

ObjectModel
{
    id: main_view_model

    // ListView index 0
    TestView1
    {
        anchors.centerIn: parent.center
        width: list_view.width
        height: list_view.height
    }

    // ListView index 1
    TestView2
    {
        anchors.centerIn: parent.center
        width: list_view.width
        height: list_view.height
    }

    // ListView index 2
    TestView3
    {
        anchors.centerIn: parent.center
        width: list_view.width
        height: list_view.height
    }

    // ListView index 3
    TestView4
    {
        anchors.centerIn: parent.center
        width: list_view.width
        height: list_view.height
    }
}

I'm still struggling a bit with the layout and anchoring concepts of QML, since I'm used to XAML. So please excuse if I'm making an obvious mistake.

Seems that "clip" property of Item will help you: Item.clip
