Struct gsk4::RoundedRect

source ·
pub struct RoundedRect { /* private fields */ }
Expand description

A rectangular region with rounded corners.

Application code should normalize rectangles using normalize(); this function will ensure that the bounds of the rectangle are normalized and ensure that the corner values are positive and the corners do not overlap.

All functions taking a RoundedRect as an argument will internally operate on a normalized copy; all functions returning a RoundedRect will always return a normalized one.

The algorithm used for normalizing corner sizes is described in the CSS specification.

GLib type: Inline allocated boxed type with stack copy semantics.

Implementations§

source§

impl RoundedRect

source

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

source

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

Borrows the underlying C value.

source

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

Borrows the underlying C value mutably.

impl RoundedRect

source

pub fn new( bounds: Rect, top_left: Size, top_right: Size, bottom_right: Size, bottom_left: Size, ) -> Self

Initializes the given RoundedRect with the given values.

This function will implicitly normalize the RoundedRect before returning.

§bounds

a graphene::Rect describing the bounds

§top_left

the rounding radius of the top left corner

§top_right

the rounding radius of the top right corner

§bottom_right

the rounding radius of the bottom right corner

§bottom_left

the rounding radius of the bottom left corner

§Returns

the initialized rectangle

source

pub fn from_rect(bounds: Rect, radius: f32) -> Self

Initializes @self to the given @bounds and sets the radius of all four corners to @radius.

§bounds

a graphene::Rect

§radius

the border radius

§Returns

the initialized rectangle

source

pub fn normalize(&mut self)

Normalizes the passed rectangle.

This function will ensure that the bounds of the rectangle are normalized and ensure that the corner values are positive and the corners do not overlap.

§Returns

the normalized rectangle

source

pub fn offset(&mut self, dx: f32, dy: f32)

Offsets the bound’s origin by @dx and @dy.

The size and corners of the rectangle are unchanged.

§dx

the horizontal offset

§dy

the vertical offset

§Returns

the offset rectangle

source

pub fn shrink(&mut self, top: f32, right: f32, bottom: f32, left: f32)

Shrinks (or grows) the given rectangle by moving the 4 sides according to the offsets given.

The corner radii will be changed in a way that tries to keep the center of the corner circle intact. This emulates CSS behavior.

This function also works for growing rectangles if you pass negative values for the @top, @right, @bottom or @left.

§top

How far to move the top side downwards

How far to move the right side to the left

§bottom

How far to move the bottom side upwards

§left

How far to move the left side to the right

§Returns

the resized RoundedRect

source

pub fn is_rectilinear(&self) -> bool

Checks if all corners of @self are right angles and the rectangle covers all of its bounds.

This information can be used to decide if ClipNode::new() or RoundedClipNode::new() should be called.

§Returns

true if the rectangle is rectilinear

source

pub fn contains_point(&self, point: Point) -> bool

Checks if the given @point is inside the rounded rectangle.

§point

the point to check

§Returns

true if the @point is inside the rounded rectangle

source

pub fn contains_rect(&self, rect: Rect) -> bool

Checks if the given @rect is contained inside the rounded rectangle.

§rect

the rectangle to check

§Returns

true if the @rect is fully contained inside the rounded rectangle

source

pub fn intersects_rect(&self, rect: Rect) -> bool

Checks if part of the given @rect is contained inside the rounded rectangle.

§rect

the rectangle to check

§Returns

true if the @rect intersects with the rounded rectangle

source

pub fn bounds(&self) -> &Rect

source

pub fn corner(&self) -> &[Size; 4]
