Event Taps Testbench
A free developer utility for exploring Quartz Event Taps
Event Taps Testbench is a free utility for software developers. Use it to explore what your applications can do with Quartz Event Taps. It is also a useful tool to test virtual software input devices, assistive applications for persons with disabilities, remote control software, and drivers for hardware input devices such as trackballs and tablets.
Event taps are Core Graphics objects that you install in the system to monitor and respond to user input to any application from a keyboard, mouse, trackpad, scroll wheel or tablet. Using Event Taps Testbench, configure and install as many event taps as you like, and monitor user input events in real time. In addition, configure how the event taps respond to user input, by performing the example actions provided, by blocking or modifying user input before the events are posted to their targets, and by posting additional events before and after the original event is posted.
In addition to being useful in its own right, Event Taps Testbench allows you to explore our PFEventTaps Framework. Visit the PFiddlesoft Frameworks page for information about downloading, using, and licensing the PFiddlesoft Frameworks, including the PFEventTaps Framework. There, you can also download the source code for Event Taps Testbench to serve as example code showing how to use the framework.
Event Taps Testbench version 1.3.6 incorporates a new version of the PFEventTaps Framework. The application can now be installed by dragging it into your Applications folder instead of running an installer package, because our PFEventTaps Framework is now embedded in the application's bundle instead of installed as a shared framework in the local Library folder.
Event Taps Testbench is FREE.
NOW AVAILABLE: NEW RELEASE! ‐ Event Taps Testbench 1.3.6, released December 2015.
