Constructor & Destructor Documentation

nana::rectangle::rectangle

(

)

a zero-size rectangle at (0, 0).

nana::rectangle::rectangle	(	int	x,
		int	y,
		unsigned	width,
		unsigned	height
	)

nana::rectangle::rectangle ( const size &  sz )

explicit

a rectangle with specified size at coordinate (0, 0).

nana::rectangle::rectangle ( const point &  pos, const size &  sz = size()  )

explicit

Member Function Documentation

noexcept

size nana::rectangle::dimension ( ) const

noexcept

Examples:

stretch_image.cpp.

rectangle & nana::rectangle::dimension ( const size &  sz )

noexcept

bool nana::rectangle::empty

(

)

const

true if width * height == 0.

bool nana::rectangle::is_hit	(	int	x,
		int	y
	)		const

bool nana::rectangle::is_hit

const

rectangle & nana::rectangle::pare_off

(

int

pixels

)

Pares the specified pixels off the rectangle.

It's equal to x += pixels; y + pixels; width -= (pixels << 1); height -= (pixels << 1);

Parameters

pixels

The number of pixels to be pared. If the number that multiples pixels twice is larger than width/height, the width/height will be zero. If the pixels is a negative number, the width/height is add the number that multiple pixels twice.

Returns

The reference of *this.

point nana::rectangle::position ( ) const

noexcept

Examples:

stretch_image.cpp.

rectangle & nana::rectangle::position ( const point &  p )

noexcept

int nana::rectangle::right ( ) const

noexcept

rectangle & nana::rectangle::shift

(

)

Swap position x and y, size width and height.
