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(). + */ typedef struct _GtkStatusbarMsg GtkStatusbarMsg; +struct _GtkStatusbarPrivate +{ + GtkWidget *frame; + GtkWidget *label; + + GSList *messages; + GSList *keys;
