Implementations

Source§

impl Rectangle

Source

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

Source

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

Source

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

Source

pub fn as_ptr(&self) -> *mut GdkRectangle

Source

pub unsafe fn from_glib_ptr_borrow<'a>( ptr: *const GdkRectangle, ) -> &'a Rectangle

Borrows the underlying C value.

Source

pub unsafe fn from_glib_ptr_borrow_mut<'a>( ptr: *mut GdkRectangle, ) -> &'a mut Rectangle

Borrows the underlying C value mutably.

Source

Source

pub fn y(&self) -> i32

Source

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

Source

pub fn width(&self) -> i32

Source

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

Source

pub fn height(&self) -> i32

Source

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

Trait Implementations

Source§

impl AsRef<RectangleInt> for Rectangle

Source§

fn as_ref(&self) -> &RectangleInt

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

impl Clone for Rectangle

Source§

fn clone(&self) -> Rectangle

Copies the inline boxed type by value with the type-specific copy function.

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

Formats the value using the given formatter. Read more
Source§

impl From<Rectangle> for Rectangle

Source§

fn from(r: Rectangle) -> Rectangle

Converts to this type from the input type.
Source§

impl From<Rectangle> for Rectangle

Source§

fn from(r: Rectangle) -> Rectangle

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

Source§

impl From<RectangleInt> for Rectangle

Source§

fn from(r: RectangleInt) -> Rectangle

Converts to this type from the input type.
Source§

impl HasParamSpec for Rectangle

Source§

type ParamSpec = ParamSpecBoxed

Source§

type SetValue = Rectangle

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecBoxedBuilder<'_, Rectangle>

Source§

fn param_spec_builder() -> <Rectangle as HasParamSpec>::BuilderFn

impl PartialEq for Rectangle

Source§

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

Tests for self and other values to be equal, and is used by ==.
1.0.0 · Source§

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
Source§

impl StaticType for Rectangle

fn static_type() -> Type

Returns the type identifier of Self.
