GI.Gdk.Structs.EventScroll

Contents

Description

Generated from button presses for the buttons 4 to 7. Wheel mice are usually configured to generate button press events for buttons 4 and 5 when the wheel is turned.

Some GDK backends can also generate “smooth” scroll events, which can be recognized by the ScrollDirectionSmooth scroll direction. For these, the scroll deltas can be obtained with eventGetScrollDeltas.

Methods

new :: MonadIO m => (ManagedPtr EventScroll -> EventScroll) -> [AttrOp EventScroll tag] -> m EventScroll

newZeroEventScroll :: MonadIO m => m EventScroll Source #

Construct a EventScroll struct initialized to zero.

Properties

deltaX

the x coordinate of the scroll delta

getEventScrollDeltaX :: MonadIO m => EventScroll -> m Double Source #

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

get eventScroll #deltaX

setEventScrollDeltaX :: MonadIO m => EventScroll -> Double -> m () Source #

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

set eventScroll [ #deltaX := value ]

deltaY

the y coordinate of the scroll delta

getEventScrollDeltaY :: MonadIO m => EventScroll -> m Double Source #

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

get eventScroll #deltaY

setEventScrollDeltaY :: MonadIO m => EventScroll -> Double -> m () Source #

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

set eventScroll [ #deltaY := value ]

device

the master device that the event originated from. Use eventGetSourceDevice to get the slave device.

clearEventScrollDevice :: MonadIO m => EventScroll -> m () Source #

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

clear #device

getEventScrollDevice :: MonadIO m => EventScroll -> m (Maybe Device) Source #

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

get eventScroll #device

setEventScrollDevice :: MonadIO m => EventScroll -> Ptr Device -> m () Source #

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

set eventScroll [ #device := value ]

direction

getEventScrollDirection :: MonadIO m => EventScroll -> m ScrollDirection Source #

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

get eventScroll #direction

setEventScrollDirection :: MonadIO m => EventScroll -> ScrollDirection -> m () Source #

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

set eventScroll [ #direction := value ]

isStop

No description available in the introspection data.

getEventScrollIsStop :: MonadIO m => EventScroll -> m Word32 Source #

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

get eventScroll #isStop

setEventScrollIsStop :: MonadIO m => EventScroll -> Word32 -> m () Source #

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

set eventScroll [ #isStop := value ]

sendEvent

True if the event was sent explicitly.

getEventScrollSendEvent :: MonadIO m => EventScroll -> m Int8 Source #

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

get eventScroll #sendEvent

setEventScrollSendEvent :: MonadIO m => EventScroll -> Int8 -> m () Source #

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

set eventScroll [ #sendEvent := value ]

state

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

getEventScrollState :: MonadIO m => EventScroll -> m [ModifierType] Source #

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

get eventScroll #state

setEventScrollState :: MonadIO m => EventScroll -> [ModifierType] -> m () Source #

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

set eventScroll [ #state := value ]

time

the time of the event in milliseconds.

getEventScrollTime :: MonadIO m => EventScroll -> m Word32 Source #

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

get eventScroll #time
