\section{\class{wxWeakRef<T>}}\label{wxweakref}

A weak reference to an object of type T, where T has type 
\helpref{wxTrackableBase}{wxTrackableBase} as one of its
base classes  (in a static or dynamic sense).

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

typedef wxWeakRef<MyClass> MyClassRef;

\membersection{wxWeakRef<T>::wxWeakRef<T>}\label{wxweakrefwxweakref}

\func{}{wxWeakRef<T>}{\param{T* }{pobj = NULL}}

Constructor.

\membersection{wxWeakRef<T>::\destruct{wxWeakRef<T>}}\label{wxweakrefdtor}

\func{}{\destruct{wxWeakRef<T>}}{\void}

Destructor.

\membersection{wxWeakRef<T>::T*}\label{wxweakreft}

\func{operator}{T*}{\void}

Returns pointer to tracked object or NULL.

\membersection{wxWeakRef<T>::operator->}\label{wxweakrefoperatorderef}

\func{T*}{operator->}{\void}

Returns pointer to tracked object or NULL.

\membersection{wxWeakRef<T>::operator=}\label{wxweakrefoperatorassign}

\func{T* operator}{operator=}{\param{T* }{pobj}}

Assigns pointer to trackable object to this weak reference.

\membersection{wxWeakRef<T>::Assign}\label{wxweakrefassign}

\func{void}{Assign}{\param{T* }{pobj}}

This uses static\_cast if possible or dynamic\_cast otherwise.

\membersection{wxWeakRef<T>::GetTrackable}\label{wxweakrefgettrackable}

\func{wxTrackableBase*}{GetTrackable}{\param{T* }{pobj}}

Returns the trackable objects to which the weak reference
points or NULL if it has been destroyed.

\membersection{wxWeakRef<T>::OnObjectDestroy}\label{wxweakrefonobjectdestroy}

\func{virtual void}{OnObjectDestroy}{\void}

Called when the tracked object is destroyed. Be default sets
internal pointer to NULL.
