Really ??

I found an article now in the QQ : Academic Solutions to Academic Problems.

So we have a great toolkit with the great mechanism of signal and slots, but when I want to implement a common thing like an observer, I cannot use this mechanism ?

That is very disappointing. The workaround mentioned in QQ15 to have a wrapper member object is really really overengineered for most things I use. Maybe a todo for Trolltech : "allow a STRAIGHTFORWARD way to define interfaces that use the signal and slot mechanism".

Best regards,
