Struct PaintCx 

pub struct PaintCx<'a> {
    pub canvas: &'a Canvas,
    pub rect: Rect,
    pub scale: f32,
    pub id: ControlId,
    pub fonts: &'a Fonts,
    /* private fields */
}

Given to paint. Nodes are read-only; only caches and render matrices are written.

rect: Rect

The control’s drawing rect in pixels.

scale: f32

Pixels per point.

id: ControlId

fonts: &'a Fonts

Implementations

impl<'a> PaintCx<'a>

pub fn base(&self) -> &'a Base

pub fn has_children(&self) -> bool

pub fn paint_child(&mut self, child: ControlId)

Draws one child: its cache when it has a valid one, else its content. The control’s content_offset moves it.

pub fn paint_children(&mut self)

Draws all children, lowest z_index first, moved by the control’s content_offset.
