Struct DrawSimpleRoadLabels

pub struct DrawSimpleRoadLabels {
    draw: Drawable,
    include_roads: Box<dyn Fn(&Road) -> bool>,
    fg_color: Color,
    pub label_covers_road: HashMap<RoadID, (Distance, Distance)>,
}

Draws labels in map-space that roughly fit on the roads. Don’t change behavior during zooming; labels are only meant to be legible when zoomed in.

Fields

draw: Drawable

include_roads: Box<dyn Fn(&Road) -> bool>

fg_color: Color

label_covers_road: HashMap<RoadID, (Distance, Distance)>

Implementations

impl DrawSimpleRoadLabels

pub fn new( ctx: &mut EventCtx<'_>, app: &dyn AppLike, fg_color: Color, include_roads: Box<dyn Fn(&Road) -> bool>, ) -> Self

Label roads that the predicate approves

pub fn empty(ctx: &EventCtx<'_>) -> Self

pub fn only_major_roads( ctx: &mut EventCtx<'_>, app: &dyn AppLike, fg_color: Color, ) -> Self

Only label major roads

pub fn all_roads( ctx: &mut EventCtx<'_>, app: &dyn AppLike, fg_color: Color, ) -> Self

pub fn draw(&self, g: &mut GfxCtx<'_>)

fn render( &mut self, ctx: &mut EventCtx<'_>, app: &dyn AppLike, timer: &mut Timer<'_>, )
