- window : QWindow

## Detailed Description

The window will become a child of the item's window, with its position, size, z-order, etc. managed by the item.

Sibling items with a higher z-order than the window container will not automatically overlap the embedded window, as the window lives on top of the Qt Quick scene. To work around this, place the sibling items inside their own dedicated child window:

     Item {
         id: someItem
         WindowContainer {
             window: foreignWindow
         }
         Window {
             parent: someItem
             Item {
                 id: siblingItem
             }
         }
     }

Similarly, child Items of the window container will not automatically overlap the embedded window. To work around this, place the child item inside a dedicated child window.

     Item {
         id: someItem
         WindowContainer {
             id: windowContainer
             window: foreignWindow
             Window {
                 parent: windowContainer
                 Item {
                     id: childItem
                 }
             }
         }
     }

If positioning and sizing of a Window via anchors is required, the Window can be wrapped in a window container:

     Item {
         id: someItem
         WindowContainer {
             anchors.fill: parent
             window: Window {
                 Item {
                 }
             }
         }
     }

Note: The window container does not interoperate with QQuickWidget, QQuickWindow::setRenderTarget(), QQuickRenderControl, or similar functionality.
