pytde/templates/annotated/menuapp3.py

"""
This template constructs an application with menus, toolbar and statusbar.
It uses an XML file (menuapp3ui.rc) to specify the menu layout; all menu
items have a corresponding action defined, but no menus are created
explicitly in code. This app has the same menu layout as menuapp2.py
