view engine/extensions/pychan/widgets/basictextwidget.py @ 330:33dd55160a9d

* Added a new method Widget.getNamedChildren * Made the distribute and mapEvents methods (a whole lot) faster. * Added a new (internal) attribute to Widget (has_name) * Added a small decorator for profiling rarely called functions.
