Detailed Description

This class extends Button by adding periodic ON_REPEAT events while the button is held down. The naming reflects the primary use case (keyboard-like repeat).

• ON_CHANGE - Any state change
• ON_PRESS - Button becomes active (switch to active state)
• ON_RELEASE - Button becomes inactive (switch to inactive state)
• ON_SHORTCLICK - Press and release within LONGPRESS_DELAY
• ON_LONGCLICK - Press and hold longer than LONGPRESS_DELAY then release
• ON_LONGPRESS - Press and hold longer than LONGPRESS_DELAY (no release)
• ON_REPEATKEY - Periodic events while holding (after LONGPRESS_DELAY)

Template parameters:

• TReader Input reader type that returns numeric codes (0 = no button, >0 = button identifier)
