Required Methods§

source

fn hit_test( &self, pipeline_id: Option<PipelineId>, point: WorldPoint, flags: HitTestFlags, ) -> HitTestResult

Does a hit test on display items in the specified document, at the given point. If a pipeline_id is specified, it is used to further restrict the hit results so that only items inside that pipeline are matched. The vector of hit results will contain all display items that match, ordered from front to back.
