Detailed Description

Gdk::Rectangle is a structure holding the position and size of a rectangle. The intersection of two rectangles can be computed with intersect(). To find the union of two rectangles use union().

has_zero_area()

bool Gdk::Rectangle::has_zero_area

(

)

const

Checks whether either the width or height are 0.

Returns

Whether this rectangle has any non-0 area.

intersect() [1/2]

Rectangle& Gdk::Rectangle::intersect

(

const Rectangle &

src2

)

Calculates the intersection of two rectangles, changing this rectangle. If the rectangles do not intersect, this rectangle's width and height is set to 0 and its x and y values are undefined.

This method returns a reference to this instance, allowing you to then call another method easily. For instance: rect.intersect(src2).join(src3);

Parameters

src2	The rectangle with which to calculate the intersection with this rectangle.

Returns

A reference to this rectangle.

intersect() [2/2]

Rectangle& Gdk::Rectangle::intersect	(	const Rectangle &	src2,
		bool &	rectangles_intersect
	)

Calculates the intersection of two rectangles, changing this rectangle. If the rectangles do not intersect, this rectangle's width and height is set to 0 and its x and y values are undefined.

This method returns a reference to this instance, allowing you to then call another method easily. For instance: rect.intersect(src2).join(src3);

Parameters

src2	The rectangle with which to calculate the intersection with this rectangle.
rectangles_intersect	This will be set to true if the rectangles intersect.

Returns

A reference to this rectangle.

join()

Rectangle& Gdk::Rectangle::join

(

const Rectangle &

src2

)

Calculates the union of two rectangles. The union of this rectangle and src2 is the smallest rectangle which includes both this rectangle and src2 within it.

This method returns a reference to this instance, allowing you to then call another method easily. For instance: rect.join(src2).intersect(src3);

Parameters

src2	The rectangle with which to calculate the union with this rectangle.

Returns

A reference to this rectangle.
