Trait Implementations

impl Tool for PickTool

fn handle( &mut self, ctx: &mut EditorContext<'_>, event: &StepEditEvent, ) -> GeopResult<Changed>

An event in the viewport, picking in what is drawn: a hover finds what a click would pick; a click picks it — joining the picks, or replacing the oldest once there are as many as the inspector takes; a click on one picked takes it out, a click on nothing clears them; Escape clears them too. A change of the picks asks again.

fn presentation(&self) -> Presentation

What it shows: the picks and what a click would pick lit, and what the answer draws.

fn inspection( &mut self, ctx: &mut EditorContext<'_>, ) -> GeopResult<Option<Inspection>>

The inspector’s answer about the picks, asked again only if they or the part changed since.
