Implementations

impl QRectF

pub fn adjust(&mut self, dx1: f64, dy1: f64, dx2: f64, dy2: f64)

Adds dx1, dy1, dx2 and dy2 respectively to the existing coordinates of the rectangle. All parameters must be finite.

impl QRectF

pub fn adjusted(&self, dx1: f64, dy1: f64, dx2: f64, dy2: f64) -> QRectF

Returns a new rectangle with dx1, dy1, dx2 and dy2 added respectively to the existing coordinates of this rectangle. All parameters must be finite.

impl QRectF

pub fn bottom(&self) -> f64

Returns the y-coordinate of the rectangle’s bottom edge.

impl QRectF

pub fn bottom_left(&self) -> QPointF

Returns the position of the rectangle’s bottom-left corner.

impl QRectF

pub fn bottom_right(&self) -> QPointF

Returns the position of the rectangle’s bottom-right corner.

impl QRectF

pub fn center(&self) -> QPointF

Returns the center point of the rectangle.

impl QRectF

pub fn contains(&self, point: &QPointF) -> bool

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

impl QRectF

pub fn height(&self) -> f64

Returns the height of the rectangle.

impl QRectF

pub fn intersected(&self, rectangle: &QRectF) -> QRectF

Returns the intersection of this rectangle and the given rectangle. Note that r.intersected(s) is equivalent to r & s.

impl QRectF

pub fn intersects(&self, rectangle: &QRectF) -> bool

Returns true if this rectangle intersects with the given rectangle (i.e. there is a non-empty area of overlap between them), otherwise returns false.

impl QRectF

pub fn is_empty(&self) -> bool

Returns true if the rectangle is empty, otherwise returns false.

An empty rectangle has width() <= 0 or height() <= 0. An empty rectangle is not valid (i.e., isEmpty() == !isValid()).

impl QRectF

pub fn is_null(&self) -> bool

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 hence not valid.

impl QRectF

pub fn is_valid(&self) -> bool

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. A valid rectangle is not empty (i.e., isValid() == !isEmpty()).

impl QRectF

pub fn margins_added(&self, margins: &QMarginsF) -> QRectF
