## Description

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). It may also have a resize grip (a triangular area in the lower right corner) which can be clicked on to resize the window containing the statusbar.

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()`.

## Details

### struct GtkStatusbar

    struct GtkStatusbar;

Contains private data that should be modified with the functions described below.

### gtk_statusbar_new ()

    GtkWidget *         gtk_statusbar_new                   (void);

`statusbar` : | a GtkStatusbar
`context_id` : | the message's context id, as returned by `gtk_statusbar_get_context_id()`

Forces the removal of a message from a statusbar's stack. The exact `context_id` and `message_id` must be specified.

`statusbar` : | a GtkStatusBar
`context_id` : | a context identifier
`message_id` : | a message identifier, as returned by `gtk_statusbar_push()`

### gtk_statusbar_remove_all ()

    void                gtk_statusbar_remove_all            (GtkStatusbar *statusbar,
                                                             guint context_id);

Forces the removal of all messages from a statusbar's stack with the exact `context_id`.

`statusbar` : | a GtkStatusBar
`context_id` : | a context identifier

Since 2.22

    void                gtk_statusbar_set_has_resize_grip   (GtkStatusbar *statusbar,
