Field Detail

renderable

protected KMLRenderable renderable

Constructor Detail

KMLScreenOverlay

public KMLScreenOverlay(String namespaceURI)

Construct an instance.

Parameters:

namespaceURI - the qualifying namespace URI. May be null to indicate no namespace qualification.

Method Detail

applyChange

public void applyChange(KMLAbstractObject sourceValues)

Overrides:

applyChange in class KMLAbstractFeature

doPreRender

protected void doPreRender(KMLTraversalContext tc,
                           DrawContext dc)

Pre-renders the screen overlay geometry represented by this KMLScreenOverlay. This initializes the screen overlay geometry if necessary, prior to pre-rendering.

Overrides:

doPreRender in class KMLAbstractFeature

Parameters:

tc - the current KML traversal context.

dc - the current draw context.

doRender

protected void doRender(KMLTraversalContext tc,
                        DrawContext dc)

Renders the screen overlay geometry represented by this KMLScreenOverlay.

Overrides:

doRender in class KMLAbstractFeature

Parameters:

tc - the current KML traversal context.

dc - the current draw context.

getOverlayXY

public KMLVec2 getOverlayXY()

getRenderable

public KMLRenderable getRenderable()

Get the renderable that represents the screen overlay. The renderable is created the first time that the overlay is rendered. Until then, the method will return null.

Returns:

The renderable, or null if the renderable has not been created yet.

getRotation

public Double getRotation()

getRotationXY

public KMLVec2 getRotationXY()

getScreenXY

public KMLVec2 getScreenXY()

getSize

public KMLVec2 getSize()

initializeRenderable

protected void initializeRenderable(KMLTraversalContext tc)

Create the renderable that will represent the overlay.

Parameters:

tc - the current KML traversal context.

onChange

public void onChange(Message msg)

Overrides:

onChange in class KMLAbstractObject
