ActionBar

open class ActionBar : Widget, ActionBarProtocol

GtkActionBar is designed to present contextual actions.

An example GtkActionBar

It is expected to be displayed below the content and expand horizontally to fill the area.

It allows placing children at the start or the end. In addition, it contains an internal centered box which is centered with respect to the full width of the box, even if the children at either side take up different amounts of space.

CSS nodes

actionbar
╰── revealer
    ╰── box
        ├── box.start
        │   ╰── [start children]
        ├── [center widget]
        ╰── box.end
            ╰── [end children]

A GtkActionBar‘s CSS node is called actionbar. It contains a revealer subnode, which contains a box subnode, which contains two box subnodes at the start and end of the action bar, with start and `end style classes respectively, as well as a center node that represents the center child.

Each of the boxes contains children packed for that side.

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

    Declaration

    Swift

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

    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 ActionBar instance.

    Declaration

    Swift

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

    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 ActionBar 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 ActionBar instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
