Description GtkInfoBar 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 GtkDialog, which has a horizontal action area at the bottom, GtkInfoBar has a vertical action area at the side. The API of GtkInfoBar is very similar to GtkDialog, allowing you to add buttons to the action area with gtk_info_bar_add_button() or gtk_info_bar_new_with_buttons(). The sensitivity of action widgets can be controlled with gtk_info_bar_set_response_sensitive(). To add widgets to the main content area of a GtkInfoBar, use gtk_info_bar_get_content_area() and add your widgets to the container. Similar to GtkMessageDialog, the contents of a GtkInfoBar can by classified as error message, warning, informational message, etc, by using gtk_info_bar_set_message_type(). GTK+ uses the message type to determine the background color of the message area. 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 action_area).
