Cannot see internal feature objects in Qt Creator Locals and Expressions debug window

Question

Cannot see internal feature objects in Qt Creator Locals and Expressions debug window

I would like to see member variables of objects during debugging in Qt Creator. I can see all the internal objects of my own objects, but I do not see, for example, members QGraphicsView.

I am also interested to know why he speaks <unavailable synchronous data>for std::map. Here is a small example:

#include <map>
#include <string>

int main(int argc, char *argv[])
{
    std::map<int, std::string> someMap;
    someMap.insert(std::make_pair(1, "cats"));
    someMap.insert(std::make_pair(2, "dogs"));
    someMap.insert(std::make_pair(3, "vlag"));
    return 0;
}
