.. _wx.Trackable:

==========================================================================================================================================
|phoenix_title|  **wx.Trackable**
==========================================================================================================================================

Add-on base class for a trackable object.          

This class maintains an internal linked list of classes of type TrackerNode and calls OnObjectDestroy() on them if this object is destroyed. The most common usage is by using the :ref:`WeakRef`  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. 

::

# This class is not expected to be used from Python.
