Documentación del constructor y destructor

QwtDoubleRect::QwtDoubleRect ( )

Constructs an rectangle with all components set to 0.0.

QwtDoubleRect::QwtDoubleRect	(	double	left,
		double	top,
		double	width,
		double	height
	)

Constructs an rectangle with x1 to x2 as x-range and, y1 to y2 as y-range.

QwtDoubleRect::QwtDoubleRect	(	const QwtDoublePoint &	p,
		const QwtDoubleSize &	size
	)

Constructs a rectangle with topLeft as the top-left corner and size as the rectangle size.

QwtDoubleRect::QwtDoubleRect ( const QRect & rect )

Documentación de las funciones miembro

double QwtDoubleRect::bottom ( ) const [inline]

Returns bottom.

QwtDoublePoint QwtDoubleRect::bottomLeft ( ) const [inline]

QwtDoublePoint QwtDoubleRect::bottomRight ( ) const [inline]

QwtDoublePoint QwtDoubleRect::center ( ) const

Returns the center point of the rectangle.

bool QwtDoubleRect::contains	(	double	x,
		double	y,
		bool	proper = `false`
	)		const

Returns true if the point (x, y) is inside or on the edge of the rectangle; otherwise returns false.

If proper is true, this function returns true only if p is inside (not on the edge).

bool QwtDoubleRect::contains	(	const QwtDoubleRect &	other,
		bool	proper = `false`
	)		const

Returns true if the rectangle other is inside this rectangle; otherwise returns false.

If proper is true, this function returns true only if other is entirely inside (not on the edge).

bool QwtDoubleRect::contains	(	const QwtDoublePoint &	p,
		bool	proper = `false`
	)		const

Returns true if the point p is inside or on the edge of the rectangle; otherwise returns false.

If proper is true, this function returns true only if p is inside (not on the edge).

double QwtDoubleRect::height ( ) const [inline]

Returns the height.

QwtDoubleRect QwtDoubleRect::intersect ( const QwtDoubleRect & other ) const

Returns the intersection of this rectangle and rectangle other. r.intersect(s) is equivalent to r&s.

bool QwtDoubleRect::intersects ( const QwtDoubleRect & other ) const

Returns true if this rectangle intersects with rectangle other; otherwise returns false.

bool QwtDoubleRect::isEmpty ( void ) const [inline]

Returns true if the rectangle is empty; otherwise returns false. An empty rectangle has a width() <= 0 or height() <= 0. An empty rectangle is not valid. isEmpty() == !isValid()

Ver también:: QwtDoubleRect::isNull, QwtDoubleRect::isValid

bool QwtDoubleRect::isNull ( ) const [inline]

Returns true if the rectangle is a null rectangle; otherwise returns false. A null rectangle has both the width and the height set to 0. A null rectangle is also empty and invalid.

Ver también:: QwtDoubleRect::isEmpty, QwtDoubleRect::isValid

bool QwtDoubleRect::isValid ( void ) const [inline]

Returns true if the rectangle is valid; otherwise returns false. A valid rectangle has a width() > 0 and height() > 0. Note that non-trivial operations like intersections are not defined for invalid rectangles. isValid() == !isEmpty()

Ver también:: isNull(), isEmpty(), and normalized().

double QwtDoubleRect::left ( ) const [inline]

Returns left.

void QwtDoubleRect::moveBottom ( double y )

moves y1() to y, leaving the size unchanged

void QwtDoubleRect::moveBy	(	double	dx,
		double	dy
	)

moves x1() by dx and y1() by dy. leaving the size unchanged

void QwtDoubleRect::moveCenter ( const QwtDoublePoint & pos )

moves the center to pos, leaving the size unchanged

void QwtDoubleRect::moveCenter	(	double	dx,
		double	dy
	)

moves the center to (x, y), leaving the size unchanged

void QwtDoubleRect::moveLeft ( double x )

moves x1() to x, leaving the size unchanged

void QwtDoubleRect::moveRight ( double x )

moves x1() to x, leaving the size unchanged

void QwtDoubleRect::moveTo	(	double	x,
		double	y
	)

moves left() to x and top() to y, leaving the size unchanged

void QwtDoubleRect::moveTo ( const QwtDoublePoint & p ) [inline]

Moves the top left corner of the rectangle to p, without changing the rectangles size.

void QwtDoubleRect::moveTop ( double y )

moves y1() to y, leaving the size unchanged

QwtDoubleRect QwtDoubleRect::normalized ( ) const

Returns a normalized rectangle, i.e. a rectangle that has a non-negative width and height.

It swaps x1 and x2 if x1() > x2(), and swaps y1 and y2 if y1() > y2().

bool QwtDoubleRect::operator!= ( const QwtDoubleRect & other ) const

Returns true if this rect and other are different; otherwise returns false.

QwtDoubleRect QwtDoubleRect::operator& ( const QwtDoubleRect & other ) const

Returns the intersection of this rectangle and rectangle other. Returns an empty rectangle if there is no intersection.

QwtDoubleRect & QwtDoubleRect::operator&= ( const QwtDoubleRect & r )

Intersects this rectangle with rectangle other.

bool QwtDoubleRect::operator== ( const QwtDoubleRect & other ) const

Returns true if this rect and other are equal; otherwise returns false.

QwtDoubleRect QwtDoubleRect::operator| ( const QwtDoubleRect & other ) const

Returns the bounding rectangle of this rectangle and rectangle other. The bounding rectangle of a nonempty rectangle and an empty or invalid rectangle is defined to be the nonempty rectangle.

QwtDoubleRect & QwtDoubleRect::operator|= ( const QwtDoubleRect & r )

Unites this rectangle with rectangle other.

double QwtDoubleRect::right ( ) const [inline]

Returns right.

void QwtDoubleRect::setBottom ( double y ) [inline]

Set bottom.

void QwtDoubleRect::setHeight ( double h ) [inline]

Set the height, by bottom = top + h;.

void QwtDoubleRect::setLeft ( double x ) [inline]

Set left.

void QwtDoubleRect::setRect	(	double	left,
		double	top,
		double	width,
		double	height
	)

Set the x-range from x1 to x2 and the y-range from y1 to y2.

void QwtDoubleRect::setRight ( double x ) [inline]

Set right.

void QwtDoubleRect::setSize ( const QwtDoubleSize & size )

Sets the size of the rectangle to size. Changes x2 and y2 only.
