Description

The Rectangle structure represents a rectangle. It is frequently used to represent the logical or ink extents of a single glyph or section of text. (See, for instance, fontGetGlyphExtents)

Synopsis

newtype Rectangle = Rectangle (ManagedPtr Rectangle)
newZeroRectangle :: MonadIO m => m Rectangle
noRectangle :: Maybe Rectangle
getRectangleHeight :: MonadIO m => Rectangle -> m Int32
setRectangleHeight :: MonadIO m => Rectangle -> Int32 -> m ()
getRectangleWidth :: MonadIO m => Rectangle -> m Int32
setRectangleWidth :: MonadIO m => Rectangle -> Int32 -> m ()
getRectangleX :: MonadIO m => Rectangle -> m Int32
setRectangleX :: MonadIO m => Rectangle -> Int32 -> m ()
getRectangleY :: MonadIO m => Rectangle -> m Int32
setRectangleY :: MonadIO m => Rectangle -> Int32 -> m ()

Exported types

newtype Rectangle Source #

Memory-managed wrapper type.

Constructors

Rectangle (ManagedPtr Rectangle)

Instances

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

newZeroRectangle :: MonadIO m => m Rectangle Source #

Construct a Rectangle struct initialized to zero.

noRectangle :: Maybe Rectangle Source #

A convenience alias for Nothing :: Maybe Rectangle.

Properties

height

height of the rectangle.

getRectangleHeight :: MonadIO m => Rectangle -> m Int32 Source #

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

get rectangle #height

setRectangleHeight :: MonadIO m => Rectangle -> Int32 -> m () Source #

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

set rectangle [ #height := value ]

width

width of the rectangle.

getRectangleWidth :: MonadIO m => Rectangle -> m Int32 Source #

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

get rectangle #width

setRectangleWidth :: MonadIO m => Rectangle -> Int32 -> m () Source #

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

set rectangle [ #width := value ]

x

X coordinate of the left side of the rectangle.

getRectangleX :: MonadIO m => Rectangle -> m Int32 Source #

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

get rectangle #x

setRectangleX :: MonadIO m => Rectangle -> Int32 -> m () Source #

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

set rectangle [ #x := value ]

y

Y coordinate of the the top side of the rectangle.

getRectangleY :: MonadIO m => Rectangle -> m Int32 Source #

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

get rectangle #y

setRectangleY :: MonadIO m => Rectangle -> Int32 -> m () Source #

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

set rectangle [ #y := value ]
