OverlayLayout

open class OverlayLayout(pointer: <Error class: unknown class><<Error class: unknown class>>) : LayoutManager

GtkOverlayLayout is the layout manager used by class@Gtk.Overlay.

It places widgets as overlays on top of the main child.

This is not a reusable layout manager, since it expects its widget to be a GtkOverlay. It is only listed here so that its layout properties get documented.
