ToplevelLayoutRef

public struct ToplevelLayoutRef : ToplevelLayoutProtocol

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

The GdkToplevelLayout struct contains information that is necessary to present a sovereign window on screen.

The GdkToplevelLayout struct is necessary for using [methodGdk.Toplevel.present].

Toplevel surfaces are sovereign windows that can be presented to the user in various states (maximized, on all workspaces, etc).

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

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

  • Create a toplevel layout description.

    Used together with gdk_toplevel_present() to describe how a toplevel surface should be placed and behave on-screen.

    The size is in ”application pixels”, not ”device pixels” (see gdk_surface_get_scale_factor()).
