Required methods

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. If the HitTestFlags argument contains the FIND_ALL flag, then the vector of hit results will contain all display items that match, ordered from front to back.
