Heh - I like Qt very much, and I wonder how someone responsible for kaa's
async stuff can find regular signal/slot mechanisms and event loops
confusing.. ;-) In fact, in Qt you do not use events directly very often;
usually you just overload one of the virtual functions to which specific
events are dispatched, and the signal/slot stuff is very convenient. (In the
C++ world, it stands out in terms of ease of use, in python there are other
fine solutions of course.)

I think I managed to write an example now myself (attached). I also tried to
separate the kaa mainloop integration from the test code, in order to prepare
for integration into kaa.base.
One thing that does not yet work is stopping the program; I need to kill
python with -9. :-(( Hope that you can fix that.

Oh, does it? That would be very sad. :-(
