Struct gdk4::Rectangle

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

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§

source§

impl Rectangle

source

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

source

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

Borrows the underlying C value.

source

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

Borrows the underlying C value mutably.

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
