GI.Gdk.Structs.Rectangle

Defines the position and size of a rectangle. It is identical to RectangleInt.

Exported types

Constructors

Rectangle (ManagedPtr Rectangle)

Instances

BoxedObject Rectangle

Methods

boxedType :: Rectangle -> IO GType

(~) AttrOpTag tag AttrSet => Constructible Rectangle tag

Methods

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

newZeroRectangle :: MonadIO m => m Rectangle

Construct a Rectangle struct initialized to zero.

noRectangle :: Maybe Rectangle

Methods

equal

rectangleEqual

Arguments

:: (HasCallStack, MonadIO m)

=> Rectangle

rect1: a Rectangle

-> Rectangle

rect2: a Rectangle

-> m Bool

Returns: True if the rectangles are equal.

Checks if the two given rectangles are equal.

Since: 3.20

intersect

rectangleIntersect

Arguments

:: (HasCallStack, MonadIO m)

=> Rectangle

src1: a Rectangle

-> Rectangle

src2: a Rectangle

-> m (Bool, Rectangle)

Returns: True if the rectangles intersect.

Calculates the intersection of two rectangles. It is allowed for dest to be the same as either src1 or src2. If the rectangles do not intersect, dest’s width and height is set to 0 and its x and y values are undefined. If you are only interested in whether the rectangles intersect, but not in the intersecting area itself, pass Nothing for dest.

union

rectangleUnion

Arguments

:: (HasCallStack, MonadIO m)

=> Rectangle

src1: a Rectangle

-> Rectangle

src2: a Rectangle

-> m Rectangle

Calculates the union of two rectangles. The union of rectangles src1 and src2 is the smallest rectangle which includes both src1 and src2 within it. It is allowed for dest to be the same as either src1 or src2.

Note that this function does not ignore 'empty' rectangles (ie. with zero width or height).
