Struct Style 

pub struct Style<'a, R: Renderer> {
    theme: &'a Theme,
    inner: &'a mut R,
    opacity: f32,
}

Theme-aware drawing surface: a &Theme paired with a &mut renderer backend. See the module docs.

Fields

theme: &'a Theme

inner: &'a mut R

opacity: f32

Dims every color resolved through this Style. 1.0 unless the draw is inside a Style::with_opacity run.

Implementations

impl<'a, R: Renderer> Style<'a, R>

pub fn new(theme: &'a Theme, inner: &'a mut R) -> Self

pub fn theme(&self) -> &Theme

The active theme — used by the render path for fonts.

pub fn renderer(&self) -> &R

The backend underneath, for a pass that needs to measure through it while drawing somewhere else (see Extent).

fn swatch(&self, role: Role) -> Swatch

fn pstroke(&self, stroke: impl Into<RoleStroke>) -> PaletteStroke

pub fn rect( &self, rect: Rect, rounding: WorldPx, fill: Role, stroke: impl Into<RoleStroke>, )

pub fn line(&self, points: Vec<Pos2>, stroke: impl Into<RoleStroke>)

pub fn line_segment(&self, points: [Pos2; 2], stroke: impl Into<RoleStroke>)

pub fn circle( &self, center: Pos2, radius: WorldPx, fill: Role, stroke: impl Into<RoleStroke>, )

pub fn circle_filled(&self, center: Pos2, radius: WorldPx, fill: Role)

pub fn add_convex_polygon( &self, points: Vec<Pos2>, fill: Role, stroke: impl Into<RoleStroke>, )

pub fn text( &self, pos: Pos2, anchor: Align2, text: impl ToString, font: &Font, color: Role, ) -> Rect

pub fn rotated_text( &self, pos: Pos2, anchor: Align2, text: impl ToString, font: &Font, color: Role, angle: Angle, )

pub fn text_wrapped( &self, pos: Pos2, anchor: Align2, text: impl ToString, font: &Font, color: Role, max_width: WorldPx, ) -> Rect

pub fn text_size(&self, text: impl ToString, font: &Font) -> Vec2

pub fn text_size_wrapped( &self, text: impl ToString, font: &Font, max_width: WorldPx, ) -> Vec2

pub fn text_layout(&self, text: &str, font: &Font, max_width: WorldPx) -> Layout

pub fn draw_image(&self, rect: Rect, image: &Asset)

pub fn image_intrinsic_size(&self, image: &Asset) -> Option<Vec2>

pub fn animator(&self) -> Option<&dyn Animator>

The frame animation behind this backend, or None offline. See Renderer::animator.

pub fn visible_world_bounds(&self) -> Option<Rect>

The visible world-space rect for viewport culling, or None on backends with no viewport (SVG export). See Renderer::visible_world_bounds.

pub fn with_opacity<T>( &mut self, factor: f32, draw: impl FnOnce(&mut Style<'_, R>) -> T, ) -> T

Draw a faded run: draw receives a Style whose colors are dimmed by factor (composing with each role’s own alpha). The fade is a swatch transform applied where roles resolve, so no backend holds fade state and every backend fades identically. Nestable — a nested run multiplies the factors. Used for ghost/dimmed previews and faint overlays.

impl<C: Canvas> Style<'_, C>

Live-canvas conveniences: when the backend is a Canvas, a tool reaches the cursor, the in-place editor, the pointer, the keyed easings and the repaint schedule straight through the Style it already holds.

pub fn set_edit_text(&mut self, edit: EditText)

pub fn set_cursor(&mut self, cursor: Cursor)

pub fn cursor(&self) -> Option<Cursor>

pub fn pointer_world(&self) -> Option<Pos2>

The pointer in world space. See Animator::pointer_world.

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

World-space rect → screen-space rect, for placing screen-space overlays (e.g. the selection bar) relative to a selection’s on-canvas bounds.

pub fn animate(&self, key: AnimKey, goal: f32, over: Duration) -> f32

The current value of the easing keyed by key. See Animator::animate.

pub fn request_repaint(&self)

pub fn request_repaint_after(&self, after: Duration)

pub fn now(&self) -> Duration

The frame clock. See Canvas::now.

pub fn pointer_kind(&self) -> PointerKind
