\qmltype XrItem \inqmlmodule QtQuick3D.Xr \inherits Node
A virtual surface in 3D space that can hold 2D user interface content.
The XrItem type is a Qt Quick 3D \l Node that represents a rectangle with \l width and \l height. It holds one Qt Quick \l Item, specified by \l contentItem, and scales it to fit. This gives a convenient way to take traditional 2D user interfaces and display them on a virtual surface that has a real world size.
Any other children of the XrItem will be treated as normal children of a Node, and will not be scaled.
For example the following code will create a virtual surface that's 1 meter by 1 meter and with a content item that's 600 pixels by 600 pixels. Note that the effect here is achieved by scaling the content item and not by rendering the content item at a higher resolution.
