North Chelmsford, MA — July 1, 2008 — PreFab Software, Inc. and Bill
Cheeseman today announced the release of version 1.1 of their free
developer utility, PreFab Event Taps Testbench. Developers can use it to
explore what their applications can do with Quartz event taps on Mac OS X
10.5 (Leopard). It is also a useful tool to test drivers for hardware input
devices such as trackballs and tablets, to test virtual software input
devices including assistive applications for persons with disabilities, and
to test remote control software.

Event Taps Testbench now comes with the PFEventTaps framework, a shared
framework that developers can license for distribution with their own
products that use Quartz event taps.

Event Taps Testbench 1.1 contains many new features and improvements,
including full support for tablet proximity and pointer events.

Event Taps Testbench 1.1 requires Mac OS X 10.5 Leopard or newer, and it

without opening System Preferences.

Dock or SystemUIServer (For Menu Extras).

examples that work correctly on Mac OS X 10.5 (Leopard).

The framework wraps Apple’s Quartz event taps C API, including many
transparent bug workarounds. It fully supports Cocoa delegate methods,
callbacks and notifications to make monitoring incoming events simple.

The PFEventTaps framework may be licensed without charge for distribution
with a free software product. A modest license fee is required to
distribute the framework with a product for which payment is requested or
required, such as donationware, shareware and commercial software. Source
code is available for a separate fee. Different terms apply to large or
established commercial software developers.
