Hi

Lets suppose I have an IDisposable class implemented.
The class has references to unmanaged resources.
Then many instances of that class are created in
many different places of the application.

In some cases, the code that creates such an instance
may insert the newly created object into a global list.
The list is maintained by another object not related to
the one that created the IDisposable object.

Is it possible for the owner of that list to receive
notifications automatically, when such an object is disposed,
by calling its Dispose(), in order to remove it from the list?

In other words I just need the kind of functionality the
VCL provides through TComponent.Notification,
TComponent.FreeNotification and TComponentList.

I think it can be done by defining an OnDisposeNotification
event by that IDisposable class and then when the object
is added to the list, hook into that event. What do you think?
Or is that functionality already in the framework?
