Detailed Description

Event registration helpers for the touch subsystem.

Use this API to subscribe to touch state changes and touch activity notifications. Two callback styles are supported:

• Object listeners (TouchEventListener*)
• Static/free function callbacks (function pointers)

Threading notes:

• Callbacks invoked from an internal worker/event thread.
