Struct gdk4::Rectangle

#[repr(C)]
pub struct Rectangle {
    pub x: i32,
    pub y: i32,
    pub width: i32,
    pub height: i32,
}

A Rectangle data type for representing rectangles.

Rectangle is identical to cairo_rectangle_t. Together with Cairo’s cairo_region_t 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_t 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.

Fields

x: i32

y: i32

width: i32

height: i32

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, other: &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, other: &Rectangle) -> Self

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
