LayoutChild

open class LayoutChild : GLibObject.Object, LayoutChildProtocol

GtkLayoutChild is the base class for objects that are meant to hold layout properties.

If a GtkLayoutManager has per-child properties, like their packing type, or the horizontal and vertical span, or the icon name, then the layout manager should use a GtkLayoutChild implementation to store those properties.

A GtkLayoutChild instance is only ever valid while a widget is part of a layout.

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

    Declaration

    Swift

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

    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 LayoutChild instance.

    Declaration

    Swift

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

    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 LayoutChild 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 LayoutChild instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
