GI.Clutter.Structs.TouchEvent

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

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

get touchEvent #axes

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

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

clearTouchEventDevice :: MonadIO m => TouchEvent -> m ()

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)

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 ()

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

set touchEvent [ #device := value ]

flags

event flags

getTouchEventFlags :: MonadIO m => TouchEvent -> m [EventFlags]

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

get touchEvent #flags

setTouchEventFlags :: MonadIO m => TouchEvent -> [EventFlags] -> m ()

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

set touchEvent [ #flags := value ]

a bit-mask representing the state of modifier keys (e.g. Control, Shift, and Alt) and the pointer buttons. See ModifierType

getTouchEventModifierState :: MonadIO m => TouchEvent -> m [ModifierType]

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

get touchEvent #modifierState
