\section{\class{wxTrackableBase}}\label{wxtrackablebase}

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 \helpref{wxWeakRef<T>}{wxweakref}
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.

\begin{verbatim}
class MyClass: public Foo, public TrackableBase
{
   // whatever
}

typedef wxWeakRef<MyClass> MyClassRef;
\end{verbatim}

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