Implementations

impl QRect

pub fn adjust(&mut self, dx1: i32, dy1: i32, dx2: i32, dy2: i32)

Adds dx1, dy1, dx2 and dy2 respectively to the existing coordinates of the rectangle.

impl QRect

pub fn adjusted(&self, dx1: i32, dy1: i32, dx2: i32, dy2: i32) -> QRect

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

impl QRect

pub fn bottom(&self) -> i32

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

Note that for historical reasons this function returns top() + height() - 1; use y() + height() to retrieve the true y-coordinate.

impl QRect

pub fn bottom_left(&self) -> QPoint

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

Note that for historical reasons this function returns QPoint(left(), top() + height() - 1).

impl QRect

pub fn bottom_right(&self) -> QPoint

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

Note that for historical reasons this function returns QPoint(left() + width() -1, top() + height() - 1).

impl QRect

pub fn center(&self) -> QPoint

Returns the center point of the rectangle.

impl QRect

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

Returns true if the given point is inside or on the edge of the rectangle, otherwise returns false. If proper is true, this function only returns true if the given point is inside the rectangle (i.e., not on the edge).

impl QRect

pub fn height(&self) -> i32

Returns the height of the rectangle.

impl QRect

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

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

impl QRect

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

Returns true if this rectangle intersects with the given rectangle (i.e., there is at least one pixel that is within both rectangles), otherwise returns false.

impl QRect

pub fn is_empty(&self) -> bool

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

An empty rectangle has a left() > right() or top() > bottom(). An empty rectangle is not valid (i.e., isEmpty() == !isValid()).

impl QRect

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 (i.e., right() == left() - 1 and bottom() == top() - 1). A null rectangle is also empty, and hence is not valid.

impl QRect

pub fn is_valid(&self) -> bool

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

A valid rectangle has a left() <= right() and top() <= bottom(). Note that non-trivial operations like intersections are not defined for invalid rectangles. A valid rectangle is not empty (i.e., isValid() == !isEmpty()).

impl QRect

pub fn left(&self) -> i32

Returns the x-coordinate of the rectangle’s left edge. Equivalent to x().

impl QRect

pub fn margins_added(&self, margins: &QMargins) -> QRect

Returns a rectangle grown by the margins.

pub fn margins_removed(&self, margins: &QMargins) -> QRect

Removes the margins from the rectangle, shrinking it.

impl QRect

pub fn move_bottom_left(&mut self, position: &QPoint)

Moves the rectangle, leaving the bottom-left corner at the given position. The rectangle’s size is unchanged.

impl QRect

pub fn move_bottom_right(&mut self, position: &QPoint)

Moves the rectangle, leaving the bottom-right corner at the given position. The rectangle’s size is unchanged.

impl QRect

pub fn move_center(&mut self, position: &QPoint)

Moves the rectangle, leaving the center point at the given position. The rectangle’s size is unchanged.

impl QRect

pub fn move_left(&mut self, x: i32)

Moves the rectangle horizontally, leaving the rectangle’s left edge at the given x coordinate. The rectangle’s size is unchanged.

impl QRect

pub fn move_right(&mut self, x: i32)

Moves the rectangle horizontally, leaving the rectangle’s right edge at the given x coordinate. The rectangle’s size is unchanged.

impl QRect

pub fn move_to(&mut self, position: &QPoint)

Moves the rectangle, leaving the top-left corner at the given position.

impl QRect

pub fn move_top(&mut self, y: i32)

Moves the rectangle vertically, leaving the rectangle’s top edge at the given y coordinate. The rectangle’s size is unchanged.

impl QRect

pub fn move_top_left(&mut self, position: &QPoint)

Moves the rectangle, leaving the top-left corner at the given position. The rectangle’s size is unchanged.

impl QRect

pub fn move_top_right(&mut self, position: &QPoint)

Moves the rectangle, leaving the top-right corner at the given position. The rectangle’s size is unchanged.

impl QRect

pub fn normalized(&self) -> QRect

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

impl QRect

pub fn right(&self) -> i32

Returns the x-coordinate of the rectangle’s right edge.

Note that for historical reasons this function returns left() + width() - 1; use x() + width() to retrieve the true x-coordinate.

impl QRect

pub fn set_bottom_left(&mut self, position: &QPoint)

impl QRect

pub fn set_bottom_right(&mut self, position: &QPoint)
