Exported types

newtype EventExpose Source #

Memory-managed wrapper type.

Constructors

EventExpose (ManagedPtr EventExpose)

Instances

WrappedPtr EventExpose Source #
Instance details Defined in GI.Gdk.Structs.EventExpose Methods wrappedPtrCalloc :: IO (Ptr EventExpose) # wrappedPtrCopy :: EventExpose -> IO EventExpose # wrappedPtrFree :: Maybe (FunPtr (Ptr EventExpose -> IO ())) #
tag ~ AttrSet => Constructible EventExpose tag Source #
Instance details Defined in GI.Gdk.Structs.EventExpose Methods new :: MonadIO m => (ManagedPtr EventExpose -> EventExpose) -> [AttrOp EventExpose tag] -> m EventExpose #

newZeroEventExpose :: MonadIO m => m EventExpose Source #

Construct a EventExpose struct initialized to zero.

noEventExpose :: Maybe EventExpose Source #

A convenience alias for Nothing :: Maybe EventExpose.

Properties

area

bounding box of region.

getEventExposeArea :: MonadIO m => EventExpose -> m Rectangle Source #

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

get eventExpose #area

the number of contiguous EventTypeExpose events following this one. The only use for this is “exposure compression”, i.e. handling all contiguous EventTypeExpose events in one go, though GDK performs some exposure compression so this is not normally needed.

getEventExposeCount :: MonadIO m => EventExpose -> m Int32 Source #

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

get eventExpose #count

setEventExposeCount :: MonadIO m => EventExpose -> Int32 -> m () Source #

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

set eventExpose [ #count := value ]

region

the region that needs to be redrawn.

clearEventExposeRegion :: MonadIO m => EventExpose -> m () Source #

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

clear #region

getEventExposeRegion :: MonadIO m => EventExpose -> m (Maybe Region) Source #

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

get eventExpose #region

setEventExposeRegion :: MonadIO m => EventExpose -> Ptr Region -> m () Source #

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

set eventExpose [ #region := value ]

sendEvent

True if the event was sent explicitly.

getEventExposeSendEvent :: MonadIO m => EventExpose -> m Int8 Source #

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

get eventExpose #sendEvent

setEventExposeSendEvent :: MonadIO m => EventExpose -> Int8 -> m () Source #

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

set eventExpose [ #sendEvent := value ]

type

the type of the event (EventTypeExpose or EventTypeDamage).

getEventExposeType :: MonadIO m => EventExpose -> m EventType Source #

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

get eventExpose #type

setEventExposeType :: MonadIO m => EventExpose -> EventType -> m () Source #

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

set eventExpose [ #type := value ]

window

the window which received the event.

clearEventExposeWindow :: MonadIO m => EventExpose -> m () Source #

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

clear #window

getEventExposeWindow :: MonadIO m => EventExpose -> m (Maybe Window) Source #

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

get eventExpose #window

setEventExposeWindow :: MonadIO m => EventExpose -> Ptr Window -> m () Source #

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

set eventExpose [ #window := value ]
