The WintabTM specification is an open industry standard interface that provides access to pointing devices such as a pen tablet, for example. The API was developed by LCS/Telegraphics.
The wintab module is a wrapper around the WintabTM Developer Kit and can be used to add tablet support to your Python application. Before you can get any data from the tablet you have to create an instance of the Context class, set the desired parameters and open the context. Once the context is open you will either receive messages from the tablet driver or you can poll the current tablet state. Either way, you will receive the tablet data via Packet objects that contain all the data that was generated by the tablet. See also the Wintab Interface Specification at http://www.pointing.com/ for more detailed usage information.
The constants used in this module are either available in the wintab module or in the wintab.constants module. The latter can be used if you want to import only the constants into your namespace.

True if the Wintab functionality is available. As the Wintab
Developer Kit is only available on Windows, this function will always
return False on other operating systems.
On Windows, this function can still return False if either the
Wintab drivers are not installed or cgkit was compiled without Wintab
support.
If this function returns False, an exception will be raised
whenever you try to call another function or instantiate a class from
this module.
