This is really a C++ question and not a gtkmm question, so this isn't
really the right list for it.  But anyway, you can remove an element
from a vector with vector<>::erase(iterator) [1].  Note that it could
be expensive to do this for a vector, it's must less expensive to
remove an element from a std::list, so if you're doing it a lot, you
might consider whether you're using the correct container type.

Yes you are right, as per my understanding also, if we need to do lots if insertion/deletion then using list is efficient, but if we need to do less insertion/deletion and mostly lookup then vector is better.
