GtkStatusbar report messages of minor importance to the user. 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). 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(). #GtkDialog another way of reporting information to the user. Contains private data that should be modified with the functions described below. Holds the data for a statusbar message. text holds the actual text string. context_id is the context that this message is associated with, and message_id is this particular message's identifier. However, these fields should not be modified directly. @text: @context_id: @message_id: Creates a new #GtkStatusbar ready for messages. @Returns: the new #GtkStatusbar. Returns a new context identifier, given a description of the actual context. @statusbar: a #GtkStatusbar. @context_description: textual description of what context the new message is being used in. @Returns: an integer id. Pushes a new message onto a statusbar's stack. @statusbar: a #GtkStatusbar. @context_id: the message's context id, as returned by gkt_statusbar_get_context_id(). @text: the message to add to the statusbar. @Returns: the message's new message id for use with gtk_statusbar_remove(). Removes the message at the top of a #GtkStatusBar's stack. @statusbar: a #GtkStatusBar. @context_id: a context identifier. Forces the removal of a message from a statusbar's stack. The exact context_id and message_id must be specified. @statusbar: a #GtkStatusBar. @context_id: a context identifier. @message_id: a message identifier, as returned by gtk_statusbar_push(). Is emitted whenever a new message gets pushed onto a statusbar's stack. @statusbar: the object which received the signal. @context_id: the context id of the relevant message/statusbar. @text: the message that was pushed. Is emitted whenever a new message is popped off a statusbar's stack. @statusbar: the object which received the signal. @context_id: the context id of the relevant message/statusbar. @text: the message that was just popped.
