Struct gtk::Allocation

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

Defines the position and size of a rectangle. It is identical to cairo_rectangle_int_t.

Implementations

impl Rectangle

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

impl Rectangle

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, or None

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) -> Rectangle

pub fn x(&self) -> i32

pub fn y(&self) -> i32

pub fn width(&self) -> i32

pub fn height(&self) -> 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) -> Rectangle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Rectangle

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

Formats the value using the given formatter.

impl From<RectangleInt> for Rectangle

fn from(r: RectangleInt) -> Rectangle

Converts to this type from the input type.

impl PartialEq<Rectangle> for Rectangle

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

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

const 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
