pub struct PaintList(_);

Expand description

A list of Shapes paired with a clip rectangle.

Implementations

impl PaintList

pub fn is_empty(&self) -> bool

pub fn add(&mut self, clip_rect: Rect, shape: Shape) -> ShapeIdx

Returns the index of the new Shape that can be used with PaintList::set.

pub fn extend(&mut self, clip_rect: Rect, shapes: Vec<Shape>)

pub fn set(&mut self, idx: ShapeIdx, clip_rect: Rect, shape: Shape)

Modify an existing Shape.

Sometimes you want to paint a frame behind some contents, but don’t know how large the frame needs to be until the contents have been added, and therefor also painted to the PaintList.

The solution is to allocate a Shape using let idx = paint_list.add(cr, Shape::Noop); and then later setting it using paint_list.set(idx, cr, frame);.

pub fn translate(&mut self, delta: Vec2)

Translate each Shape and clip rectangle by this much, in-place
