Question

I’m writing a widget kit for the Nano-X window system. In my base class view, I have a vector defined:

std::vector<RSMKit::View *> children;

Is it possible to call a function (GrReparentWindow in this case) when an item is added or removed from the vector so that the newly added widget can be shown?

Answer 1

No. Do not inherit from std::vector. Just encapsulate it.

template<typename T> struct MyVector
{
private:
    std::vector<T> items;
public:
    void push_back (const T& x)
    {
        // Do something here
        items.push_back(x);
    }
    // etc
};
