OverlayLayout

open class OverlayLayout : LayoutManager, OverlayLayoutProtocol

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 OverlayLayout type acts as a reference-counted owner of an underlying GtkOverlayLayout instance. It provides the methods that can operate on this data type through OverlayLayoutProtocol conformance. Use OverlayLayout as a strong reference or owner of a GtkOverlayLayout instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the OverlayLayout instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GtkOverlayLayout>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the OverlayLayout instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GtkOverlayLayout>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the OverlayLayout instance.

    Declaration

    Swift

    @inlinable
override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object
    Show on GitHub

  • Optional initialiser from a non-mutating gconstpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the OverlayLayout instance.

    Declaration

    Swift

    @inlinable
override public init!(gconstpointer op: gconstpointer?)

    Parameters

    op

    pointer to the underlying object

    Parameters

    op

  • Reference intialiser for a related type that implements OverlayLayoutProtocol Will retain GtkOverlayLayout.

    Declaration

    Swift

    @inlinable
public init<T>(overlayLayout other: T) where T : OverlayLayoutProtocol

    Parameters

    other

    an instance of a related type that implements OverlayLayoutProtocol
