BoxLayout

open class BoxLayout : LayoutManager, BoxLayoutProtocol

GtkBoxLayout is a layout manager that arranges children in a single row or column.

Whether it is a row or column depends on the value of its [propertyGtk.Orientable:orientation] property. Within the other dimension all children all allocated the same size. The GtkBoxLayout will respect the [propertyGtk.Widget:halign] and [propertyGtk.Widget:valign] properties of each child widget.

If you want all children to be assigned the same size, you can use the [propertyGtk.BoxLayout:homogeneous] property.

If you want to specify the amount of space placed between each child, you can use the [propertyGtk.BoxLayout:spacing] property.

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

    Declaration

    Swift

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

    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 BoxLayout instance.

    Declaration

    Swift

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

    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 BoxLayout 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 BoxLayout instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
