GtkStatusbar implements
 AtkImplementorIface.Detailed 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 gtkStatusbarGetContextId, 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 gtkStatusbarNew.
  
Messages are added to the bar's stack with gtkStatusbarPush.
  
The message at the top of the stack can be removed using gtkStatusbarPop. 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 gtkStatusbarRemove.References
