Includes

#include <gtk/gtk.h>

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).

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.

Functions

gtk_statusbar_new ()

                              const gchar *context_description);

Returns a new context identifier, given a description of the actual context. Note that the description is not shown in the UI.

Parameters

statusbar

a GtkStatusbar

 

context_description

textual description of what context the new message is being used in

 

Returns

an integer id


gtk_statusbar_push ()

guint
gtk_statusbar_push (GtkStatusbar *statusbar,
                    guint context_id,
                    const gchar *text);

Pushes a new message onto a statusbar’s stack.

Parameters
