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 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 its message_id was recorded at the time it was added. This is done using gtk_statusbar_remove().

Details

GtkStatusbar

typedef struct _GtkStatusbar GtkStatusbar;

Returns : the new GtkStatusbar.

gtk_statusbar_get_context_id ()

guint               gtk_statusbar_get_context_id        (GtkStatusbar *statusbar,
                                                         const gchar *context_description);

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.

gtk_statusbar_push ()

guint               gtk_statusbar_push                  (GtkStatusbar *statusbar,
                                                         guint context_id,
                                                         const gchar *text);

Pushes a new message onto a statusbar's stack.

statusbar : a GtkStatusbar.
context_id : the message's context id, as returned by gtk_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().

gtk_statusbar_pop ()

void                gtk_statusbar_pop                   (GtkStatusbar *statusbar,
                                                         guint context_id);

Removes the message at the top of a GtkStatusBar's stack.

statusbar : a GtkStatusBar.
context_id : a context identifier.

gtk_statusbar_remove ()

void                gtk_statusbar_remove                (GtkStatusbar *statusbar,

                                                         guint message_id);

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().
