where's the code for Calculator showcase?

Where can I see the code for the calculator? I mean the one with fancy background? B开发者_如何学Goy the way, it looks very nice!!

In general, I could not find enough material for custom-made decoration, by searching the documents. Please let me know where I can learn deeper about rendering and widget decoration.

Thanks in advance :)

You can find the source code of the calculator page in the qooxdoo SDK under

qooxdoo/application/showcase/source/class/showcase/page/theme/calc/

There is also a standalone version of the calculator on github. You can find more information about theming in the qooxdoo manual:

• Theming
• Appearance
• Custom Themes
• Decorators
