[Qt-interest] Why do Qt collection classes not offer signals and slots?

Yes, but Qt does not provide one and I'm a one library man.

I wish the QT container classes were designed with two exposed parts.
1 - A non reference counted, less convenient, but faster container and
2 - A slower but more convenient reference counted container (which uses
     a #1 for its inner shared part.)
All we get now is #2 where there is  a #1 inside just dying to get out.

I have some classes which are large collections of Qt containers.
They get so large that I have to give them their own reference counted layer
(using QTSharedData and QTSharedDataPointer.)
Then, all of the reference counting on the sub-containers is a waste of 
time.
