Alignment

open class Alignment : Bin, AlignmentProtocol

The GtkAlignment widget controls the alignment and size of its child widget. It has four settings: xscale, yscale, xalign, and yalign.

The scale settings are used to specify how much the child widget should expand to fill the space allocated to the GtkAlignment. The values can range from 0 (meaning the child doesn’t expand at all) to 1 (meaning the child expands to fill all of the available space).

The align settings are used to place the child widget within the available area. The values range from 0 (top or left) to 1 (bottom or right). Of course, if the scale settings are both set to 1, the alignment settings have no effect.

GtkAlignment has been deprecated in 3.14 and should not be used in newly-written code. The desired effect can be achieved by using the GtkWidget:halign, GtkWidget:valign and GtkWidget:margin properties on the child widget.

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

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • 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 Alignment instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • 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 Alignment instance.

    Declaration

    Swift

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

    Parameters

    op

    gpointer to the underlying object

  • 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 Alignment instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • Optional 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 Alignment instance.

    Declaration

    Swift

    @inlinable
    public init!(_ op: UnsafePointer<GtkAlignment>?)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Alignment instance.

    Declaration

    Swift

    @inlinable
    public init!(_ op: UnsafeMutablePointer<GtkAlignment>?)

    Parameters

    op

    pointer to the underlying object

  • Designated initialiser from the underlying C data type. Will retain GtkAlignment. i.e., ownership is transferred to the Alignment instance.

    Declaration

    Swift

    @inlinable
    public init(retaining op: UnsafeMutablePointer<GtkAlignment>)

    Parameters

    op

    pointer to the underlying object

  • Reference intialiser for a related type that implements AlignmentProtocol Will retain GtkAlignment.

    Declaration

    Swift

    @inlinable
    public init<T>(alignment other: T) where T : AlignmentProtocol

    Parameters

    other

    an instance of a related type that implements AlignmentProtocol
