Statusbar

open class Statusbar : Box, StatusbarProtocol

A GtkStatusbar is usually placed along the bottom of an application’s main GtkWindow. It may provide a regular commentary of the application’s status (as is usually the case in a web browser, for example), or may be used to simply output a message when the status changes, (when an upload is complete in an FTP client, for example).

Status bars in GTK+ maintain a stack of messages. The message at the top of the each bar’s stack is the one that will currently be displayed.

Any messages added to a statusbar’s stack must specify a context id that is used to uniquely identify the source of a message. This context id can be generated by gtk_statusbar_get_context_id(), given a message and the statusbar that it will be added to. Note that messages are stored in a stack, and when choosing which message to display, the stack structure is adhered to, regardless of the context identifier of a message.

One could say that a statusbar maintains one stack of messages for display purposes, but allows multiple message producers to maintain sub-stacks of the messages they produced (via context ids).

Status bars are created using gtk_statusbar_new().

Messages are added to the bar’s stack with gtk_statusbar_push().

The message at the top of the stack can be removed using gtk_statusbar_pop(). A message can be removed from anywhere in the stack if its message id was recorded at the time it was added. This is done using gtk_statusbar_remove().

CSS node

GtkStatusbar has a single CSS node with name statusbar.

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

    Declaration

    Swift

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

    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 Statusbar instance.

    Declaration

    Swift

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

    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 Statusbar 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 Statusbar 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 Statusbar instance.

    Declaration

    Swift

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

    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 Statusbar instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

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

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • Reference intialiser for a related type that implements StatusbarProtocol Will retain GtkStatusbar.

    Declaration

    Swift

    @inlinable
    public init<T>(statusbar other: T) where T : StatusbarProtocol

    Parameters

    other

    an instance of a related type that implements StatusbarProtocol
