Detailed Description

Mouse / pen button indices.

This enum-like struct defines integer indices for common mouse/pen buttons. The values are intended to be used as button indices (0..n-1) when reporting which single button triggered an event. Use -1 to indicate "no button" (for example, touch events or pure move events).

Mapping convention:

• 0 => left button
• 1 => right button
• 2 => middle button
• n => additional buttons (if present) use subsequent indices

Note

Use the separate bitmask field (e.g., pressedButtons) to represent the current set of pressed buttons; bit i corresponds to button index i.
