Description

Used for touch events. type field will be one of EventTypeTouchBegin, EventTypeTouchUpdate, EventTypeTouchEnd or EventTypeTouchCancel.

Touch events are grouped into sequences by means of the sequence field, which can also be obtained with eventGetEventSequence. Each sequence begins with a EventTypeTouchBegin event, followed by any number of EventTypeTouchUpdate events, and ends with a EventTypeTouchEnd (or EventTypeTouchCancel) event. With multitouch devices, there may be several active sequences at the same time.
