NSEvent has a method to get the event's subtype:
Getting Custom Event Information
– data1
– data2
– subtype
Can this same subtype be accessed from a CGEvent without first converting it to an NSEvent?
CGEventRef eventCG = ...;
NSEvent *eventNS = [NSEvent eventWithCGEvent:eventCG];
short subtypeNS = eventNS.subtype;
short subtypeCG = ???;
The CGEvent docs mention the mouse event subtypes, with seem to correspond with the mouse subtypes from IOLLEvent.h. However I'm specifically interested in finding the subtypes for System Defined CGEvents.
Those would be the NX_SUBTYPE_AUX_CONTROL_BUTTONS, etc., below or CG alternatives.
/* sub types for mouse and move events */
#define NX_SUBTYPE_DEFAULT 0
#define NX_SUBTYPE_TABLET_POINT 1
#define NX_SUBTYPE_TABLET_PROXIMITY 2
#define NX_SUBTYPE_MOUSE_TOUCH 3
/* sub types for system defined events */
#define NX_SUBTYPE_POWER_KEY 1
#define NX_SUBTYPE_AUX_MOUSE_BUTTONS 7
/*
* NX_SUBTYPE_AUX_CONTROL_BUTTONS usage
*
* The incoming NXEvent for other mouse button down/up has event.type
* NX_SYSDEFINED and event.data.compound.subtype NX_SUBTYPE_AUX_MOUSE_BUTTONS.
* Within the event.data.compound.misc.L[0] contains bits for all the buttons
* that have changed state, and event.data.compound.misc.L[1] contains the
* current button state as a bitmask, with 1 representing down, and 0
* representing up. Bit 0 is the left button, bit one is the right button,
* bit 2 is the center button and so forth.
