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

[Hendrik Fuß]

Hi folks,

I was just wondering, I thought this was the most obvious thing to have... If Qt containers supported signals and slots, you could write e.g.:

QVector<int> * myVector = new QVector<int>();
connect(myVector, SIGNAL(elementAdded(int)), this, updateList());

Is there a reason for the lack of signals in Qt's collection classes? Or am I missing something?

cheers
Hendrik
