public final class PeerBoardV
extends BoardV

A view of a peer board rendered as an HTML table cell containing an SVG drawing. It differs from an ordinary board view in having a pin indicator. The pin indicator decorates the node view of the anchor whenever the anchor is contained within the board and is pinned. The bottom of the indicator extends below the boundary of the track, overlapping whatever is beneath. Its pointer events are therefore disabled.
