autoscroll

public boolean autoscroll

tracker

public Tracker tracker

estimateListener

public FilteredEstimateListener estimateListener

Constructor Detail

ReticleOverlay

public ReticleOverlay(MapView view,
                      PlacelabWithProxy daemon)

ReticleOverlay

public ReticleOverlay(MapView view,
                      Tracker tracker)

Method Detail

setTracker

public void setTracker(Tracker _tracker)

setDaemon

public void setDaemon(PlacelabWithProxy daemon)

setAutoScroll

public void setAutoScroll(boolean scroll)

mapChanged

public void mapChanged(MapBacking map)

Description copied from class: MapViewOverlay

When the mapview has its maps switched, this callback is given to allow the overlay to update its data for the new map.

Specified by:

mapChanged in class MapViewOverlay

mapZoomed

public void mapZoomed(double zoom)

Description copied from class: MapViewOverlay

When the mapview is zoomed, this callback is given to allow you to update your overlay. Generally you shouldn't need to do anything here because your glyphs will automatically resize and point translate for the zoom.

Overrides:

mapZoomed in class MapViewOverlay

getName

public java.lang.String getName()

Description copied from class: MapViewOverlay

Returns the name that is displayed in menus and so forth referring to this overlay. In this way, applications using mapviews can build menus that allow toggling of overlays in a generic fashion.

Specified by:

getName in class MapViewOverlay

estimateUpdated

public void estimateUpdated(Tracker t,
                            Estimate est,
                            Measurement m)

Description copied from interface: EstimateListener

Implement this method to respond to updates from the Tracker(s) you are registered with.

Specified by:

estimateUpdated in interface EstimateListener

Parameters:

t - the Tracker producing the Estimate

est - the Estimate produced by the Tracker

m - the latest Measurement used by the Tracker to produce the Estimate

plotReticle

public void plotReticle(Tracker t,
                        Estimate est,
                        int reticleIdx)

updateReticle

public void updateReticle(int idx,
                          int x,
                          int y,
                          int radius)

setDrawConfidence

public void setDrawConfidence(boolean flag)

getDrawConfidence

public boolean getDrawConfidence()

getSuggestedArea

public org.eclipse.swt.graphics.Rectangle getSuggestedArea()

Description copied from class: MapViewOverlay

If your overlay has an area that it would like to keep onscreen if possible, then you can return that here. If not, just return null. The mapview may use this information to do autoscrolling.

Overrides:

getSuggestedArea in class MapViewOverlay

getTopGlyph

public Glyph getTopGlyph()

Description copied from class: MapViewOverlay

Returns the top glyph in this overlay

Specified by:

getTopGlyph in class MapViewOverlay
