\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).

class MyClass: public Foo, public TrackableBase

{
|
|
// whatever

|
\func{}{wxWeakRef<T>}{\param{T* }{pobj = NULL}}
|
|
|
|
Constructor.
|
|
|
|
\membersection{wxWeakRef<T>::\destruct{wxWeakRef<T>}}\label{wxweakrefdtor}
|

|
\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.
