path <-distance: point|event|graphical -> int

If the argument is a point object or event object (in which case the event<-position is used), compute the distance of this point to the path-line. If the path is interpolated, the distance to the interpolation is computed.

If the argument is a graphical, use graphical<-distance.

See also line<-distance and graphical->in_event_area.

path <-end: -> point

Position (in graphical<-device coordinate system) of the last point of the path. See also path<-start.

path<-start

path <-point: near=point|event, max_distance=[int] -> point

Return (member) point object that is closest to the given position and within the specified maximum distance (default 10 pixels). When an event is passed, this is translated into the position of the event.

See also path<-segment.

Defaults: The default maximum distance (2nd argument) is 10.

Diagnostics: Fails silently if no such point exist.

path <-segment: near=point|event, accept=[0..] -> point

Return member point that is the start of a line-segment nearest to the indicated position or event graphical<-position. May be used to interactively path->insert new points:

send(Path, click_gesture(left, '', single,
                         message(@receiver, insert,
                                 ?(@event, position, @receiver?device),
                                 ?(@receiver, segment, @event)))).

See also path<-point.

path <-start: -> point

First point of the path (equivalent to Path?points?head). See also path<-end.
