## Detailed Description

Text status indicator This widget is used to display status information.

Messages are pushed and poped onto a message stack. When text is pushed it replaces the old contents. The old text is restored when popped.

It derives from Gtk::HBox so that additional information can be added easily.

The Statusbar widget looks like this:

Returns a new context identifier, given a description of the actual context.

Note that the description is not shown in the UI.

Parameters:

  context_description | Textual description of what context the new message is being used in.

Returns:
  An integer id.

Gtk::Widget* Gtk::Statusbar::get_message_area | ( |  | ) |

Retrieves the box containing the label widget.

Since gtkmm 2.20:

Returns:
  A Gtk::Box.

const Gtk::Widget* Gtk::Statusbar::get_message_area | ( |  | ) | const

Retrieves the box containing the label widget.

Since gtkmm 2.20:

Returns:
  A Gtk::Box.

const GtkStatusbar* Gtk::Statusbar::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GtkObject.

Reimplemented from Gtk::HBox.

| ) |  | `[protected, virtual]`

void Gtk::Statusbar::pop | ( | guint | context_id = `0` | ) |

Removes the first message in the Gtk::StatusBar'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.

Parameters:

  context_id | A context identifier.

guint Gtk::Statusbar::push | ( | const Glib::ustring & | text,
|  | guint | context_id = `0`
| ) |  |

Pushes a new message onto a statusbar's stack.

Parameters:

  text | The message to add to the statusbar.
  context_id | The message's context id, as returned by get_context_id()

void Gtk::Statusbar::remove_all_messages | ( | guint | context_id = `0` | ) |

Forces the removal of all messages from a statusbar's stack with the exact context_id.

Since gtkmm 2.22:

Parameters:

  context_id | A context identifier.

void Gtk::Statusbar::remove_message | ( | guint | message_id,
|  | guint | context_id = `0`
| ) |  |

Forces the removal of a message from a statusbar's stack.

The exact context_id and message_id must be specified.

Parameters:

  message_id | A message identifier, as returned by push().
