Detailed Description

An sf::Shape subclass that draws a rectangle with rounded corners.

RoundedRectangle extends sf::Shape by generating vertex geometry for a rectangle whose corners are replaced by circular arcs. The number of vertices per arc is configurable, trading smoothness for polygon count.

It is the underlying shape type used by ml::Rectangle — most user code interacts with RoundedRectangle indirectly through that class. Direct use is appropriate when you need fine control over corner radius or point count without the additional framework layers.

Usage

ml::RoundedRectangle rr({200.f, 80.f}, 12.f, 10);
rr.setFillColor(sf::Color::Blue);
rr.setPosition({100.f, 100.f});
window.draw(rr);

Setting radius to 0 produces a standard sharp-cornered rectangle.

Constructor & Destructor Documentation

RoundedRectangle()

ml::RoundedRectangle::RoundedRectangle ( const sf::Vector2f & size = sf::Vector2f(0, 0), float radius = 0.f, unsigned int cornerPointCount = 8 )

explicit

Construct a rounded rectangle.

Parameters

size	Width and height of the rectangle in pixels. Defaults to {0, 0}.
radius	Corner arc radius in pixels. Defaults to 0 (sharp corners). Clamped to half the shorter side so corners never overlap.
cornerPointCount	Number of vertices used to approximate each corner arc. Higher values produce smoother corners at the cost of more geometry. Defaults to 8.

Member Function Documentation

getCornerPointCount()

unsigned int ml::RoundedRectangle::getCornerPointCount

(

)

const

Return the current per-corner vertex count.

Returns

Number of vertices per corner arc.

getPoint()

virtual sf::Vector2f ml::RoundedRectangle::getPoint ( std::size_t index ) const

overridevirtual

Return the position of a single vertex.

Required by sf::Shape for geometry generation.

Parameters

index

Vertex index in [0, getPointCount()).

Returns

Local-space position of the vertex.

Implements sf::Shape.

getPointCount()

virtual std::size_t ml::RoundedRectangle::getPointCount ( ) const

overridevirtual

Return the total number of shape vertices.

Equal to cornerPointCount × 4 (one arc per corner). Required by sf::Shape.

Returns

Total vertex count.

Implements sf::Shape.

getRadius()

float ml::RoundedRectangle::getRadius

(

)

const

Return the current corner arc radius.

Returns

Corner radius in pixels.

getSize()

const sf::Vector2f & ml::RoundedRectangle::getSize

(

)

const

Return the current size of the rectangle.

Returns

Width and height in pixels.

setCornerPointCount()

void ml::RoundedRectangle::setCornerPointCount

(

unsigned int

count

)

Set the number of vertices per corner arc.

Triggers geometry regeneration.

Parameters

count

Vertex count per corner. Must be at least 1.

setRadius()

void ml::RoundedRectangle::setRadius

(

float

radius

)

Set the corner arc radius.

Triggers geometry regeneration. Values larger than half the shorter side are clamped automatically.

Parameters

radius

Corner radius in pixels.

setSize()

void ml::RoundedRectangle::setSize

(

const sf::Vector2f &

size

)

Set the width and height of the rectangle.

Triggers geometry regeneration.

Parameters

size	New size in pixels.
