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.
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().
Functions
gtk_statusbar_new ()
GtkWidget *
gtk_statusbar_new (void);
Creates a new GtkStatusbar ready for messages.
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. Note that the description is not shown in the UI.
gtk_statusbar_push ()
guint gtk_statusbar_push (GtkStatusbar *statusbar,guint context_id,const gchar *text);
Pushes a new message onto a statusbar's stack.
Parameters
statusbar |
||
context_id |
the message's context id, as returned by
|
|
text |
the message to add to the statusbar |
gtk_statusbar_pop ()
void gtk_statusbar_pop (GtkStatusbar *statusbar,guint context_id);
Removes the first message in the GtkStatusBar's stack with the given context id.
Note that this may not change the displayed message, if the message at the top of the stack has a different context id.
gtk_statusbar_remove ()
void gtk_statusbar_remove (GtkStatusbar *statusbar,guint context_id,guint message_id);
Forces the removal of a message from a statusbar's stack.
The exact context_id
and message_id
must be specified.
Parameters
statusbar |
a GtkStatusBar |
|
context_id |
a context identifier |
|
message_id |
a message identifier, as returned by |
gtk_statusbar_remove_all ()
void gtk_statusbar_remove_all (GtkStatusbar *statusbar,guint context_id);
Forces the removal of all messages from a statusbar's
stack with the exact context_id
.
Since: 2.22
gtk_statusbar_set_has_resize_grip ()
void gtk_statusbar_set_has_resize_grip (GtkStatusbar *statusbar,gboolean setting);
Sets whether the statusbar has a resize grip.
TRUE by default.
gtk_statusbar_get_has_resize_grip ()
gboolean
gtk_statusbar_get_has_resize_grip (GtkStatusbar *statusbar);
Returns whether the statusbar has a resize grip.
gtk_statusbar_get_message_area ()
GtkWidget *
gtk_statusbar_get_message_area (GtkStatusbar *statusbar);
Retrieves the box containing the label widget.
Since: 2.20
