def get_name(self):
if hasattr(self, '<STR_LIT>'):<EOL><INDENT>return self.widget_name<EOL><DEDENT>return self.__class__.__name__<EOL>
Returns the class name of this widget.

Be careful when overriding this. If ``self.widget_name`` is set, you
should always return that in order to allow to register this widget
class several times with different names.
