Methods

wrappedPtrCalloc :: IO (Ptr VideoRectangle)

wrappedPtrCopy :: VideoRectangle -> IO VideoRectangle

wrappedPtrFree :: Maybe (FunPtr (Ptr VideoRectangle -> IO ()))

(~) AttrOpTag tag AttrSet => Constructible VideoRectangle tag

Methods

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

newZeroVideoRectangle :: MonadIO m => m VideoRectangle

Construct a VideoRectangle struct initialized to zero.

noVideoRectangle :: Maybe VideoRectangle

A convenience alias for Nothing :: Maybe VideoRectangle.

Properties

h

height of the rectangle

getVideoRectangleH :: MonadIO m => VideoRectangle -> m Int32

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

get videoRectangle #h

setVideoRectangleH :: MonadIO m => VideoRectangle -> Int32 -> m ()

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

set videoRectangle [ #h := value ]

w

width of the rectangle

getVideoRectangleW :: MonadIO m => VideoRectangle -> m Int32

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

get videoRectangle #w

setVideoRectangleW :: MonadIO m => VideoRectangle -> Int32 -> m ()

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

set videoRectangle [ #w := value ]

x

X coordinate of rectangle's top-left point

getVideoRectangleX :: MonadIO m => VideoRectangle -> m Int32

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

get videoRectangle #x

setVideoRectangleX :: MonadIO m => VideoRectangle -> Int32 -> m ()

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

set videoRectangle [ #x := value ]

y

Y coordinate of rectangle's top-left point

getVideoRectangleY :: MonadIO m => VideoRectangle -> m Int32

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

get videoRectangle #y

setVideoRectangleY :: MonadIO m => VideoRectangle -> Int32 -> m ()

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

set videoRectangle [ #y := value ]
