const class gfx::Border

sys::Obj
  gfx::Border

@Js
@Serializable { simple=true }

Source

Modes width, style, color, and radius of a rectangular border.

colorBottom

const Color colorBottom := black

Source

Color of bottom side, default is black.

colorLeft

const Color colorLeft := black

Source

Color of left side, default is black.

colorRight

const Color colorRight := black

Source

Color of right side, default is black.

colorTop

const Color colorTop := black

Source

Color of top side, default is black.

defVal

const static Border defVal := Border.fromStr("0")

Source

Default is zero pixel border.

equals

virtual override Bool equals(Obj? obj)

Source

Equality is based on string format.

fromStr

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

Source

Parse a border from string (see toStr). If invalid and checked is true then throw ParseErr otherwise return null. The string formatted as four optional parts, where each part may have 1 to 4 values:

border := [width] [style] [color] [radius]
width  := top ["," right ["," bottom ["," left]]]
style  := top ["," right ["," bottom ["," left]]]
color  := top ["," right ["," bottom ["," left]]]
radius := top-left ["," top-right ["," bottom-right ["," bottom-left]]]

Width and radius must be integers, color must match Color string format, and style must be "solid", "inset", or "outset". If one side is not specified, it is reflected from the opposite side:

a      =>  a,a,a,a
a,b    =>  a,b,a,b
a,b,c  =>  a,b,c,b

Examples:

Border("2")          =>  2 solid #000000 0
Border("#abc")       =>  1 solid #aabbcc 0
Border("2 inset 3")  =>  2 inset #000000 3
Border("0,1,2,3")    =>  0,1,2,3 solid #000000 0
Border("0,1,2 #00f") =>  0,1,2 solid #0000ff 0
hash

virtual override Int hash()

Source

Hash is based on string format.
