type

Rect

@Js @Serializable { simple=true } const class Rect : Obj

Represents the x,y coordinate and w,h size of a rectangle.

constructors

fromStr	Parse from comma or space separated string.
make	Construct with x, y, w, h.
makeInt	Construct with x, y, w, h as integers.
makePosSize	Construct from a Point and Size instance

fields

defVal	Default instance is 0, 0, 0, 0.
h	Height
w	Width
x	X coordinate
y	Y coordinate

methods

contains	Return true if x,y is inside the bounds of this rectangle.
equals	Return if obj is same Rect value.
hash	Return hash of x, y, w, and h.
intersection	Compute the intersection between this rectangle and that rectangle.
intersects	Return true if this rectangle intersects any portion of that rectangle
pos	Get the x, y coordinate of this rectangle.
size	Get the w, h size of this rectangle.
toStr	Return `"x y w h"`
union	Compute the union between this rectangle and that rectangle, which is the bounding box that exactly contains both rectangles.

Slot Details

contains

Bool contains(Point pt)

Return true if x,y is inside the bounds of this rectangle.

defVal

const static Rect defVal := Rect.<ctor>(0.0, 0.0, 0.0, 0.0)

Default instance is 0, 0, 0, 0.

equals

virtual override Bool equals(Obj? obj)

Return if obj is same Rect value.

fromStr

static new fromStr(Str s, Bool checked := true)

Parse from comma or space separated string. If invalid then throw ParseErr or return null based on checked flag.

h

const Float h

Height

hash

virtual override Int hash()

Return hash of x, y, w, and h.

intersection

Rect intersection(Rect that)

Compute the intersection between this rectangle and that rectangle. If there is no intersection, then return defVal.

intersects

Bool intersects(Rect that)

Return true if this rectangle intersects any portion of that rectangle

make

new make(Float x, Float y, Float w, Float h)

Construct with x, y, w, h.

makeInt

new makeInt(Int x, Int y, Int w, Int h)

Construct with x, y, w, h as integers.

makePosSize

new makePosSize(Point p, Size s)

Construct from a Point and Size instance

pos

Point pos()

Get the x, y coordinate of this rectangle.

size

Size size()

Get the w, h size of this rectangle.

toStr

virtual override Str toStr()

Return "x y w h"

union

Rect union(Rect that)

Compute the union between this rectangle and that rectangle, which is the bounding box that exactly contains both rectangles.

w

const Float w

Width

x

const Float x

X coordinate

y

const Float y

Y coordinate
