PFiddlesoft updates the PFAssistive Framework


SUMMARY: PFiddlesoft today released new versions of its PFiddlesoft Frameworks, PFAssistive Framework 3.3.0 and PFEventTaps Framework 1.3.6. The PFiddlesoft Frameworks are Cocoa frameworks for writing assistive applications for persons with disabilities using Apple's Accessibility and Quartz Event Taps APIs on Mac OS X.

QUECHEE, VERMONT -- November 3, 2013 -- PFiddlesoft today announced that it has updated both of the PFiddlesoft Frameworks, the PFAssistive Framework and the PFEventTaps Framework. The PFiddlesoft Frameworks are two Cocoa frameworks for writing assistive applications for persons with disabilities using Apple's Accessibility and Quartz Event Taps APIs on Mac OS X.

The PFAssistive Framework was updated to version 3.3.0 and the PFEventTaps Framework was updated to version 1.3.6. The PFAssistive Framework now supports the new accessibility features added in Mavericks.

PFiddlesoft has also posted two free developer utility projects, Accessibility Testbench and PFAssistive Testbench, complete with source code. Both of these projects show developers how to implement the new security mechanism in OS X 10.9 Mavericks for granting access to assistive applications to monitor and control the computer using accessibility features.

The PFAssistive Framework was created in 2003 as the engine driving PFiddlesoft’s highly regarded 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. Both frameworks have been revised and updated over a period of years, and they have demonstrated their power and reliability in PFiddlesoft’s commercial and free developer utilities.

The frameworks are written using Objective-C. They support the Intel 64-bit architecture using reference counted memory management and ARC. Developers can now license the PFiddlesoft Frameworks for distribution or 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 modest 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. For more information, go to
