Welcome to qooxdoo! It is easy to create your own impressive and versatile applications. For detailed information on how to create a typical rich internet application (RIA) please see the external documentation to get started.
For the impatient, here is a short version as well:
Use the tool/bin/create-application.py script to setup a new application.
This will create a minimal directory structure of an application, which is ready to
be built and run. Within the newly created application folder run the command
generate.py source-all to generate a development version of your app.
Open source/index.html in your browser and see your first application in action. You can
then go on and extend it into an application of your liking by changing the
Application.js class file below the source/class/ folder. The command
generate.py build generates an optimized and compressed version of your application,
located at build/index.html.
Open the included API viewer to display and search the entire API reference of the framework.
Also have a look at the readme.txt and license.txt.
