Field Detail

altitudeMode

protected int altitudeMode

annotation

protected GlobeAnnotation annotation

Annotation used to render the balloon.

position

protected Position position

Constructor Detail

GlobeAnnotationBalloon

public GlobeAnnotationBalloon(String text,
                              Position position)

Create the balloon.

Parameters:

text - Text to display in the balloon. May not be null.

position - The balloon's initial position. May not be null.

Method Detail

computePosition

protected void computePosition(DrawContext dc)

Compute the annotation position, and set it in the annotation.

Specified by:

computePosition in class AbstractAnnotationBalloon

Parameters:

dc - Draw context.

createAnnotation

protected GlobeAnnotation createAnnotation()

Create an annotation to render the balloon.

Specified by:

createAnnotation in class AbstractAnnotationBalloon

Returns:

The new annotation.

getAltitudeMode

public int getAltitudeMode()

Returns the balloon's altitude mode. See GlobeBalloon.setAltitudeMode(int) for a description of the modes.
