This class extends LRect by adding support for rounded corners.

Constructor & Destructor Documentation

LRRect()

LRRect ( const LRect &  rect = { 0 }, Int32  radTL = 0, Int32  radTR = 0, Int32  radBR = 0, Int32  radBL = 0  )

inlinenoexcept

Constructs a rounded rectangle.

rect	The base rectangle.
radTL	Radius of the top-left corner.
radTR	Radius of the top-right corner.
radBR	Radius of the bottom-right corner.
radBL	Radius of the bottom-left corner.

Member Function Documentation

isValid()

bool isValid ( ) const

inlinenoexcept

Checks if the rectangle is valid.

A rectangle is valid if its width and height are non-negative, each corner radius is non-negative, and the sum of adjacent corner radii does not exceed the respective width or height.

Returns

true if the rectangle is valid, false otherwise.

operator==()

constexpr bool operator== ( const LRRect &  other ) const

inlineconstexpr

Compares two rounded rectangles for equality.

Parameters

other

The rectangle to compare with.

Returns

true if all properties match, false otherwise.

operator!=()

constexpr bool operator!= ( const LRRect &  other ) const

inlineconstexpr

Compares two rounded rectangles for inequality.

Parameters

other

The rectangle to compare with.

Returns

true if any property differs, false otherwise.
