LEOHandlerID

Introduction

A data type used for identifying handlers without tedious string comparisons.

Typedefs

LEOHandlerID

LEOHandlerID

typedef uint32_t LEOHandlerID;  

Discussion

Every handler name maps to a handler ID. Since handler names are case-insisensitive, "mouseUp", "MOUSEUP" and "mouseup" would all map to the same handler ID. Not unlike a "selector" in Objective C.
