This is a small test application that demonstrates how you can easily use Qooxdoo from a Scala.js project. This application can also serve as a template to build your own application.
All you really need to do is implement a function with the following signature:
someFunctionName(app: qx.application.Standolone): Unit
and then register it:
qx.registry.registerMainMethod(someFunctionName)
Within this function you can use all the Qooxdoo widgets you like and it is behaves just like a normal Qooxdoo application.
You can use the provided test application as an example to see how to create some simple widgets.
