@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.
