HBox

open class HBox : Box, HBoxProtocol

GtkHBox is a container that organizes child widgets into a single row.

Use the GtkBox packing interface to determine the arrangement, spacing, width, and alignment of GtkHBox children.

All children are allocated the same height.

GtkHBox has been deprecated. You can use GtkBox instead, which is a very quick and easy change. If you have derived your own classes from GtkHBox, you can simply change the inheritance to derive directly from GtkBox. No further changes are needed, since the default value of the GtkOrientable:orientation property is GTK_ORIENTATION_HORIZONTAL.

If you have a grid-like layout composed of nested boxes, and you don’t need first-child or last-child styling, the recommendation is to switch to GtkGrid. For more information about migrating to GtkGrid, see Migrating from other containers to GtkGrid.

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

    Declaration

    Swift

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

    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 HBox instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object

override public init!(gconstpointer op: gconstpointer?)

    Parameters
