public class Statusbar : Box, Implementor, Buildable, Orientable
A Statusbar is usually placed along the bottom of an application's main Window.
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 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 Statusbar.
Messages are added to the bar’s stack with push.
GtkStatusbar has a single CSS node with name statusbar.
