Struct gdk4::Rectangle

#[repr(transparent)]
pub struct Rectangle { /* private fields */ }

A Rectangle data type for representing rectangles.

Rectangle is identical to cairo_rectangle_t. Together with Cairo’s cairo::Region data type, these are the central types for representing sets of pixels.

The intersection of two rectangles can be computed with intersect(); to find the union of two rectangles use union().

The cairo::Region type provided by Cairo is usually used for managing non-rectangular clipping of graphical operations.

The Graphene library has a number of other data types for regions and volumes in 2D and 3D.

Implementations

impl Rectangle

pub fn contains_point(&self, x: i32, y: i32) -> bool

Returns true if @self contains the point described by @x and @y.

x

X coordinate

y

Y coordinate

Returns

true if @self contains the point

pub fn intersect(&self, src2: &Rectangle) -> Option<Rectangle>

Calculates the intersection of two rectangles.

It is allowed for @dest to be the same as either @self or @src2. If the rectangles do not intersect, @dest’s width and height is set to 0 and its x and y values are undefined. If you are only interested in whether the rectangles intersect, but not in the intersecting area itself, pass None for @dest.

src2

a Rectangle

Returns

true if the rectangles intersect.

dest

return location for the intersection of @self and @src2

pub fn union(&self, src2: &Rectangle) -> Rectangle

Calculates the union of two rectangles.

The union of rectangles @self and @src2 is the smallest rectangle which includes both @self and @src2 within it. It is allowed for @dest to be the same as either @self or @src2.

Note that this function does not ignore ‘empty’ rectangles (ie. with zero width or height).

src2

a Rectangle

Returns

dest

return location for the union of @self and @src2

impl Rectangle

pub fn new(x: i32, y: i32, width: i32, height: i32) -> Self

pub fn x(&self) -> i32

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

pub fn y(&self) -> i32

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

pub fn width(&self) -> i32

pub fn set_width(&mut self, width: i32)

pub fn height(&self) -> i32

pub fn set_height(&mut self, height: i32)

Trait Implementations

impl AsRef<RectangleInt> for Rectangle

fn as_ref(&self) -> &RectangleInt

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Rectangle

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Rectangle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Rectangle> for Rectangle

fn from(r: Rectangle) -> Self

Converts to this type from the input type.

impl From<Rectangle> for Rectangle

fn from(r: Rectangle) -> Self

Converts to this type from the input type.

impl From<Rectangle> for Rectangle

fn from(r: Rectangle) -> Self

Converts to this type from the input type.

impl From<Rectangle> for Rectangle

fn from(r: Rectangle) -> Self

Note that converting between a cairo::Rectangle and Rectangle will probably lead to precisison errors. Use cautiously.

impl From<Rectangle> for RectangleInt

fn from(r: Rectangle) -> Self

Converts to this type from the input type.

impl From<RectangleInt> for Rectangle

fn from(r: RectangleInt) -> Self

Converts to this type from the input type.

impl PartialEq<Rectangle> for Rectangle

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StaticType for Rectangle

fn static_type() -> Type

Returns the type identifier of Self.

impl Copy for Rectangle

impl Eq for Rectangle
