mtouch_event

Structure that contains details common to INPUT_CLASS_MTOUCH input events.

Synopsis:

typedef struct mtouch_event {
    input_event_e event_type ;
    _Uint64t timestamp ;
    _Uint32t seq_id ;
    _Uint32t contact_id ;
    _Int32t x ;
    _Int32t y ;
    _Uint32t width ;
    _Uint32t height ;
    _Uint32t orientation ;
    _Uint32t pressure ;
    _Uint32t contact_type ;
    _Uint32t select ;
}mtouch_event_t;

Data:

input_event_e event_type: The event type of the INPUT_CLASS_MTOUCH event.

_Uint64t timestamp: Timestamp, based on realtime clock, when the INPUT_CLASS_MTOUCH event occurred.

_Uint32t seq_id: The sequence number for the event; seq_id is incremented each time a new touch-related event occurs.

_Uint32t contact_id: The order of occurrence for multiple touch contacts.

_Int32t x: The x screen position, in pixels, for the event.

_Int32t y: The y screen position, in pixels, for the event.

_Uint32t width: The width, in pixels, of the touch area.

_Uint32t height: The height, in pixels, of the touch area.

_Uint32t orientation: The orientation of the contact.

_Uint32t pressure: The pressure of the touch contact, ranging from 0 to 2^32 - 1.

_Uint32t contact_type: The contact type.; Valid contact types are of type contact_type_e.

_Uint32t select: The selected buttons.

Description:

The mtouch_event structure represents information that is common to all input events of class INPUT_CLASS_MTOUCH. This information is provided by the input device driver whenever an INPUT_CLASS_MTOUCH event occurs.
