'parent' was not such a bad idea, but you have to get at actual object
instances, not the class objects. here is a general way of accessing
live objects in the "parent" application:
parent.qx.core.Init.getInstance().getApplication().viewer
(because if you look at the code, the DemoBrowser instance was added to
the Application instance as the 'viewer' member). this also implies that
you need some reference from your application object to access other
objects. i think you get the pattern.
this uses 'relative' addressing with 'parent'. there is also an
'absolute' addressing scheme using 'window':
window.top.qx.core.Init.getInstance().getApplication().viewer
see what works best for you.
