Rect (int16_t left, int16_t top, int16_t right, int16_t bottom)

A constructor used to create a Rect instance based on the coordinates of the four boundaries.

Rect (const Rect &other)

A constructor used to create a Rect instance by copying another rectangle.

Rect (const Rect &&other)

A constructor used to create a Rect instance by copying another rectangle.

SetRect (int16_t left, int16_t top, int16_t right, int16_t bottom)

void 

Sets the coordinates of the four boundaries of a rectangle.

GetWidth () const

int16_t
