The objective is to compress such calls so that only one unique call exists in the event queue for a given tuple of (sender object, sender signal, receiver object, receiver slot). This is the only sane way to do it, without having to make changes to source or target objects, an...

Because thequeue,priority_queue, andstackcontainers do not support iterators, they do not implement generic interfaces and cannot be accessed cross-assembly. Example 1 Description In this example, we declare a C++ class that contains private STL/CLR member data. We then declare public methods to ...
