   3
   4 Add-on base class for a trackable object. This class maintains
   5 an internal linked list of classes of type wxTrackerNode and
   6 calls OnObjectDestroy() on them if this object is destroyed.
   7 The most common usage is by using the \helpref{wxWeakRef<T>}{wxweakref}
   8 class template which automates this. This class has no public
   9 API. Its only use is by deriving another class from it to
  10 make it trackable.

  14 {
  15    // whatever
  16 }

  18 typedef wxWeakRef<MyClass> MyClassRef;

  34 The only difference to \helpref{wxTrackableBase}{wxtrackablebase} is
  35 that this class adds a virtual table to enable dynamic\_cast query for
  36 wxTrackable.
