Preprocessor macro definitions for the mtouch_driver.h header file in the libinputevents library
#include <input/>
#define MTOUCH_CAPABILITIES_CONTACT_ID (1 << 0)
The multitouch device capability to support contact IDs.
#define MTOUCH_CAPABILITIES_COORDS (1 << 1)
The multitouch device capability to support coordinates.
#define MTOUCH_CAPABILITIES_CONTACT_COUNT (1 << 2)
The multitouch device capability to support contact counts.
#define MTOUCH_CAPABILITIES_WIDTH (1 << 3)
The multitouch device capability to support touch widths.
#define MTOUCH_CAPABILITIES_HEIGHT (1 << 4)
The multitouch device capability to support touch heights.
#define MTOUCH_CAPABILITIES_ORIENTATION (1 << 5)
The multitouch device capability to support touch orientations.
#define MTOUCH_CAPABILITIES_PRESSURE (1 << 6)
The multitouch device capability to support touch pressures (or signal strength for capacitive touchscreens).
#define MTOUCH_CAPABILITIES_RATE_SET (1 << 7)
The multitouch device capability to support setting of an event rate.
#define MTOUCH_CAPABILITIES_SEQ_ID (1 << 8)
The multitouch device capability to support sequence IDs.
#define MTOUCH_CAPABILITIES_CONTACT_TYPE (1 << 9)
The multitouch device capability to support contact type.
#define MTOUCH_DEFAULT_WIDTH 1
The width when MTOUCH_CAPABILITIES_WIDTH isn't set or if this capability isn't available.
#define MTOUCH_DEFAULT_HEIGHT 1
The height when MTOUCH_CAPABILITIES_HEIGHT isn't set or if this capability isn't available.
#define MTOUCH_DEFAULT_PRESSURE 1
The pressure when MTOUCH_CAPABILITIES_PRESSURE isn't set or if this this capability isn't available.
#define MTOUCH_FLAGS_INCONSISTENT_DIGIT_ORDER (1 << 0)
A multi-touch device flag.
Devices that report touch data for individual fingers in an inconsistent order should set this flag. Use this flag, along with the MTOUCH_FLAGS_INCONSISTENT_CONTACT_IDS flag, to describe the relationship between the digit index and the contact ID.
#define MTOUCH_FLAGS_INCONSISTENT_CONTACT_IDS (1 << 1)
A multitouch device flag.
Devices that don't have contact IDs assigned as a zero-based index should set this flag. Use this flag along with the MTOUCH_FLAGS_INCONSISTENT_DIGIT_ORDER flag to describe the relationship between the digit index and the contact ID.
#define MTOUCH_FLAGS_SINGLE_COORDINATE_PACKET (1 << 2)
A multitouch device flag.
Devices that report touch data for single set of coordinates in an individual packet. Use this flag along with the MTOUCH_FLAGS_INCONSISTENT_DIGIT_ORDER flag to describe the relationship between the digit index and the contact ID.
