Added:
trunk/ui/src/gui/compat.py
Modified:
trunk/ui/src/gui/__init__.py
Log:
Add some code to glue the old gui code to the new application code
I wrote the application code when moving to kaa.canvas. Since kaa.canvas
doesn't scale much we are waiting for kaa.candy to be finished. To
include the new application code now, a small compat layer is needed.
