+    @class wxTrackable
+
+    Add-on base class for a trackable object. This class maintains an internal
+    linked list of classes of type wxTrackerNode and calls OnObjectDestroy() on
+    them if this object is destroyed. The most common usage is by using the
+    wxWeakRef<T> class template which automates this. This class has no public
+    API. Its only use is by deriving another class from it to make it trackable.
+
+    @code
+    class MyClass: public Foo, public wxTrackable
+    {
+        // whatever
+    }
+
+    typedef wxWeakRef<MyClass> MyClassRef;
