gtk-sharp2.10.0.0Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details.Report messages of minor importance to the user.The Statusbar widget displays textual messages to the user. Statusbars are typically placed at the bottom of application s.A Statusbar 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).As a finishing touch to the StatusBar, it can have a "resize grip" added in the lower right corner. This is a triangular area that 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 that is used to uniquely identify the source of a message. This can be generated with , given a message. 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.Messages are added to the bar's stack with , and the message at the top of the stack can be removed using . A message can be removed from anywhere in the stack if it's was recorded at the time it was added. This is done using .
