The programmer builds an application by creating subclasses that override various methods of the bases classes, thereby implementing the functionality wanted. Overriding functionality can often be done on various different levels, i.e. to handle clicks in a single dialog window in a non-standard way it is not necessary to override the complete event handling.</p> <div class="admonition note"> <p class="first admonition-title">Note</p> <p class="last">This module has been removed in Python 3.x.</p> </div> <p>Work on the <tt class="xref docutils literal"><span class="pre">FrameWork</span></tt> has pretty much stopped, now that <tt class="xref docutils literal"><span class="pre">PyObjC</span></tt> is available for full Cocoa access from Python, and the documentation describes only the most important functionality, and not in the most logical manner at that.
