OverlayLayoutRef

public struct OverlayLayoutRef : OverlayLayoutProtocol, GWeakCapturing

GtkOverlayLayout is the layout manager used by GtkOverlay.

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 only listed here so that its layout properties get documented.

The OverlayLayoutRef type acts as a lightweight Swift reference to an underlying GtkOverlayLayout instance. It exposes methods that can operate on this data type through OverlayLayoutProtocol conformance. Use OverlayLayoutRef only as an unowned reference to an existing GtkOverlayLayout instance.

  • ptr 
    Untyped pointer to the underlying `GtkOverlayLayout` instance.

    For type-safe access, use the generated, typed pointer overlay_layout_ptr property instead.
