Name
GtkStatusbar -- report messages of minor importance to the user.
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.
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 it's message_id was recorded at the time it was added. This is done using gtk_statusbar_remove().
