Struct gdk::EventTouch

pub struct EventTouch(_);

Used for touch events. type field will be one of EventType::TouchBegin, EventType::TouchUpdate, EventType::TouchEnd or EventType::TouchCancel.

Touch events are grouped into sequences by means of the sequence field, which can also be obtained with gdk_event_get_event_sequence(). Each sequence begins with a EventType::TouchBegin event, followed by any number of EventType::TouchUpdate events, and ends with a EventType::TouchEnd (or EventType::TouchCancel) event. With multitouch devices, there may be several active sequences at the same time.
