\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}

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