Public Methods

Rect()

Default constructor

Rect(int x, int y, int w, int h)

Constructor for making a rectangle from coordinates of origin, width and height

Rect(const Point &p, const Size &s)

Constructor for making a rectangle from the origin point and size

bool operator==(const Rect &r) const

Operator for comparing two Rects.

void operator+=(const Point &p)

void operator-=(const Point &p)

Rect operator+(const Point &p) const

Rect operator-(const Point &p) const

Operators for doing simple arithmetic with Rects (ie.

Documentation

A simple class that represents a rectangle in 2D space. It also has some overloaded operators for manipulating rectangles.

Point origin

Top left point (origin)

Size dim

The size of the rectangle

Rect()

Default constructor

Rect(int x, int y, int w, int h)

Constructor for making a rectangle from coordinates of origin, width and height

Rect(const Point &p, const Size &s)

Constructor for making a rectangle from the origin point and size

bool operator==(const Rect &r) const

Operator for comparing two Rects. Two rectangles are equal if they have the same origin point and size.

void operator+=(const Point &p)

void operator-=(const Point &p)

Rect operator+(const Point &p) const

Rect operator-(const Point &p) const

Operators for doing simple arithmetic with Rects (ie. moving).

bool Intersects(const Rect &r) const

Returns true if this rectangle intersects with the passed rectangle (excluding the edges)

Point topLeft() const

Point bottomRight() const

Size size() const

int x() const

int y() const

int x2() const

int y2() const

int w() const

int h() const

void topLeft(const Point& p)

void bottomRight(const Point& p)
