+/** This 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 horizontal action area at the bottom, InfoBar has a vertical 
+ * action area at the side.
+ *
+ * The API is very similar to Dialog, allowing you to add buttons to the action 
+ * area with add_button(). The sensitivity of action widgets can be controlled 
+ * with set_response_sensitive(). To add widgets to the main content area, use 
+ * get_content_area() and add your widgets to the container.
+ *
+ * Similar to MessageDialog, the contents can by classified as error message, 
+ * warning, informational message, etc, by using set_message_type(). This 
+ * determines the background color of the message area.
