So do I, but I have already measured it Wink

And, BTW, better benchmark against Vector...

(BTW2, Array does not have that At or Add reference problem - it never invalidates references).

So I suppose your Array class is built on top of a sort of linked list... not a contiguous area, right ?

Basically *implemented* as Vector<T*>...

p.s.: just a small question about object ownership...
When you write

a.Add(aControl);

Who has the ownership of aControl ? Array a[] or who created aControl ?

Very well, getting to the real issues Smile

If aControl is an instance of widget, such statement is simply impossible (because it requires some form of copy, which Ctrl lacks).

Quote:

In former case this :

OpenGLExample aControl;
a.Add(aControl);

Should be wrong; in the latter case this :

Yes. You cannot copy widgets.

Quote:

a.Create<OpenGLExample>();

should be wrong. As you did show the latter example on this thread, I suppose a[] has the ownership...

Yes, although the whole idea of "ownership" is a little bit moot here. The widgets is simply an element of the container, the "ownership" issue is simple and obvious...
