GI.Gtk.Objects.InfoBar

InfoBar is a widget that can be used to show messages to the user without showing a dialog. It is often temporarily shown at the top or bottom of a document. In contrast to Dialog, which has a action area at the bottom, InfoBar has an action area at the side.

The API of InfoBar is very similar to Dialog, allowing you to add buttons to the action area with infoBarAddButton or gtk_info_bar_new_with_buttons(). The sensitivity of action widgets can be controlled with infoBarSetResponseSensitive. To add widgets to the main content area of a InfoBar, use infoBarGetContentArea and add your widgets to the container.

Similar to MessageDialog, the contents of a InfoBar can by classified as error message, warning, informational message, etc, by using infoBarSetMessageType. GTK+ may use the message type to determine how the message is displayed.

A simple example for using a InfoBar:

C code

GtkWidget *widget, *message_label, *content_area;
GtkWidget *grid;
GtkInfoBar *bar;

// set up info bar
widget = gtk_info_bar_new ();
bar = GTK_INFO_BAR (widget);
grid = gtk_grid_new ();

gtk_widget_set_no_show_all (widget, TRUE);
message_label = gtk_label_new ("");
content_area = gtk_info_bar_get_content_area (bar);
gtk_container_add (GTK_CONTAINER (content_area),
                   message_label);
gtk_info_bar_add_button (bar,
                         _("_OK"),
                         GTK_RESPONSE_OK);
g_signal_connect (bar,
                  "response",
                  G_CALLBACK (gtk_widget_hide),
                  NULL);
gtk_grid_attach (GTK_GRID (grid),
                 widget,
                 0, 2, 1, 1);

// ...

// show an error message
gtk_label_set_text (GTK_LABEL (message_label), "An error occurred!");
gtk_info_bar_set_message_type (bar,
                               GTK_MESSAGE_ERROR);
gtk_widget_show (bar);

GtkInfoBar as GtkBuildable

The GtkInfoBar implementation of the GtkBuildable interface exposes the content area and action area as internal children with the names “content_area” and “action_area”.

GtkInfoBar supports a custom <action-widgets> element, which can contain multiple <action-widget> elements. The “response” attribute specifies a numeric response, and the content of the element is the id of widget (which should be a child of the dialogs actionArea).

CSS nodes

GtkInfoBar has a single CSS node with name infobar. The node may get one of the style classes .info, .warning, .error or .question, depending on the message type.
