Description

Used for touch events.

The type field will be one of EventTypeTouchBegin, EventTypeTouchEnd, EventTypeTouchUpdate, or EventTypeTouchCancel.

Touch events are grouped into sequences; each touch sequence will begin with a EventTypeTouchBegin event, progress with EventTypeTouchUpdate events, and end either with a EventTypeTouchEnd event or with a EventTypeTouchCancel event.

With multi-touch capable devices there can be multiple event sequence running at the same time.

Since: 1.10

Methods

Properties

axes

reserved

getTouchEventAxes :: MonadIO m => TouchEvent -> m Double Source #

get touchEvent #axes

setTouchEventAxes :: MonadIO m => TouchEvent -> Double -> m () Source #

Set the value of the “axes” field. When overloading is enabled, this is equivalent to

set touchEvent [ #axes := value ]

device

the device that originated the event. If you want the physical device the event originated from, use eventGetSourceDevice

Set the value of the “device” field to Nothing. When overloading is enabled, this is equivalent to

clear #device

getTouchEventDevice :: MonadIO m => TouchEvent -> m (Maybe InputDevice) Source #

Get the value of the “device” field. When overloading is enabled, this is equivalent to

get touchEvent #device

setTouchEventDevice :: MonadIO m => TouchEvent -> Ptr InputDevice -> m () Source #

Set the value of the “device” field. When overloading is enabled, this is equivalent to

set touchEvent [ #device := value ]

flags
