Finally got around to try it out - works like a charm, this makes
component based design of applications really f**king awesome, excuse
me French.
I will force myself to write a slice about that soon. This should also
go into the official documentation since this IS A KEY feature of
web2py for developing component based application GUIs (not just
dynamic web pages).
As a further note it should be stated that the above is just the basic
example, together with two small functions the signal slot mechanism
of qt can be imitated http://en.wikipedia.org/wiki/Signals_and_slots
For that a global dictionary would hold all components and their
target ids ... you might get the idea
:)
