PFiddlesoft (http://pfiddlesoft.com/frameworks/) has released version 3.6.1 of PFAssistive Framework. The PFiddlesoft Frameworks help developers write assistive Mac applications for persons with disabilities using Apple's Accessibility and Quartz Event Taps APIs [application programming interfaces] on OS X.

It was updated to complete the implementation of full support for subclassing by client applications that need special or additional features. The PFAssistive Framework was created in 2003 as the engine driving PFiddlesoft’s UI Browser application for developers and for users of Apple’s AppleScript GUI Scripting technology.

The framework supports and enhances Apple's Accessibility API. The PFEventTaps Framework was created in 2007 as the engine underlying PFiddlesoft’s free Event Taps Testbench utility for developers. The framework supports and enhances Apple's Quartz Event Taps API.

The frameworks are written using Objective-C. They support the Intel 64-bit architecture using reference counted memory management or ARC, and they support client applications written in Objective-C or Swift. Developers can license the PFiddlesoft Frameworks for distribution or for use with their own products that use Apple's Accessibility and Quartz Event Taps technologies.

The frameworks may be licensed free of charge for personal use or for distribution or use with a free software product. A license fee is required to distribute or use the frameworks with a product for which payment is requested or required. Source code is available for a separate fee. Different terms apply to large or established commercial software developers.
