Detailed Description

Class encapsulating operations on a Rectangle.

Member Function Documentation

Rect & CEGUI::Rect::constrainSize	(	const Size &	max_sz,
		const Size &	min_sz
	)

check the size of the Rect object and if it is bigger than max_sz or smaller than min_sz, resize it so it isn't.

Parameters

max_sz	Size object that describes the maximum dimensions that this Rect should be limited to.
min_sz	Size object that describes the minimum dimensions that this Rect should be limited to.

Returns

'this' Rect object after the constrain operation

References getSize(), setHeight(), and setWidth().

Rect & CEGUI::Rect::constrainSizeMax

(

const Size &

sz

)

check the size of the Rect object and if it is bigger than sz, resize it so it isn't.

Parameters

sz	Size object that describes the maximum dimensions that this Rect should be limited to.

Returns

'this' Rect object after the constrain operation

References getHeight(), getWidth(), setHeight(), and setWidth().

Rect & CEGUI::Rect::constrainSizeMin

(

const Size &

sz

)

check the size of the Rect object and if it is smaller than sz, resize it so it isn't.

Parameters

sz	Size object that describes the minimum dimensions that this Rect should be limited to.

Returns

'this' Rect object after the constrain operation

References getHeight(), getWidth(), setHeight(), and setWidth().

Rect CEGUI::Rect::getIntersection

(

const Rect &

rect

)

const

return a Rect that is the intersection of 'this' Rect with the Rect 'rect'

Note

It can be assumed that if d_left == d_right, or d_top == d_bottom, or getWidth() == 0, or getHeight() == 0, then 'this' rect was totally outside 'rect'.

bool CEGUI::Rect::isPointInRect

(

const Point &

pt

)

const

Return true if the given Point falls within this Rect.

Parameters

pt	Point object describing the position to test.

Returns

true if position pt is within this Rect's area, else false

Rect & CEGUI::Rect::offset

(

const Point &

pt

)

Applies an offset the Rect object.

Parameters

pt	Point object containing the offsets to be applied to the Rect.

Returns

this Rect after the offset is performed
