Implementations

impl EditPolygon

pub fn new( ctx: &EventCtx<'_>, points: Vec<Pt2D>, polygon_draggable: bool, ) -> Self

fn add_polygon_to_world(&self, ctx: &EventCtx<'_>, world: &mut World<Obj>)

fn rebuild_world(&mut self, ctx: &EventCtx<'_>)

fn rebuild_one_point(&mut self, ctx: &EventCtx<'_>, idx: usize)

pub fn event(&mut self, ctx: &mut EventCtx<'_>) -> bool

True if the polygon is modified

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

pub fn get_ring(&self) -> Result<Ring>

Could fail if the user edits the ring and makes it invalid
