public final class VoteTrackV
extends Composite

A view of a vote track. It shows the anchor node's voters left, peers center, and candidate right. The anchor node itself may have a pin indicator. Vote flow is depicted left to right with the volume indicated by numbers.

         votersV                    peersV            candidateV
             \                        |                  /
    >>>>>>>>>>>>>>>>>>>>> --- >>>>>>>>>>>>>>>>>>>> --- >>>>>
                           |              /\        |
                      flow volume         /    flow volume
                                        pin

When the track is invisible, e.g. because no poll is staged, then a podium may become visible to serve as a staging control for the actor.

                                            ( )
                                              \
                                             podium

Acknowledgement: The segmented arrow motif is borrowed from Christian Weilbach's design of a progress track for quantitative summation accounts. See his mock-ups 2b and 2g.

Constructor Detail

VoteTrackV

public VoteTrackV(VoteTrack _track,
          boolean isBottomFixed)

Constructs a VoteTrackV.

Parameters:

isBottomFixed - answers whether this VoteTrackV is to be the bottom-fixed instance. You may create at most one bottom-fixed instance.

Method Detail

i

public static VoteTrackV i(StageV stageV)

The staged instance of VoteTrackV, or null if none is staged.

iBottomFixed

static VoteTrackV iBottomFixed()

The instance of VoteTrackV that is fixed to the bottom of the viewport, or null if there is none.

candidateV

public CandidateV candidateV()

The view of the candidate.

isMoving

public boolean isMoving()

Answers whether this view is physically moving in order to visualize a change of anchor and a consequent logical shift in votespace. The return value is bound to property name moving. Components themselves ought to withold showing a change of anchor or related changes till immediately after the motion has stopped. Each major component must also explicitly reshow itself after the changes are rendered, as this view may have hidden it at some point as part of the motion.

peersBoardV

public PeerBoardV peersBoardV()

The view of the peers board.

track

public VoteTrack track()

The track on which this view is modelled.

votersBoardV

public BoardV votersBoardV()

The view of the voters board.
