Maybe a good way for you to start is:
- have a simple gui (like one button as in the gui skeleton)
- on button press, create a qx.io.remote.Request object, go out to the
server
- when the data arrives, display it in a second widget (a list, a text
field, ...)
That should give you a good grip on the basic mechanics.
If you want to look at an example, search for qx.io.remote.Request in
the Demobrowser source. There is e.g. a method 'dataLoader' that
populates the navigation tree on the left in the GUI.
