Field Detail

screenLocation

protected Point screenLocation

Indicates this balloon's screen location. The screen location's coordinate system has its origin in the upper left corner of the WorldWindow, with the y-axis pointing right and the x-axis pointing down. Initialized to a non-null value at construction.

Constructor Detail

ScreenBrowserBalloon

public ScreenBrowserBalloon(String text,
                            Point point)

Constructs a new ScreenBrowserBalloon with the specified text content and screen location.

Parameters:

text - the balloon's initial text content.

point - the balloon's initial screen location, in AWT coordinates (origin at upper left corner of the WorldWindow).

Throws:

IllegalArgumentException - if either text or point are null.

Method Detail

computeBalloonPoints

protected void computeBalloonPoints(DrawContext dc)

Computes and stores this balloon's screen coordinates. This assigns balloon coordinate properties as follows:

• screenOffset - the balloon frame's screen-coordinate offset from this balloon's screen location.
• screenRect - the balloon frame's screen-coordinate rectangle.
• screenExtent - this balloon's screen-coordinate bounding rectangle.
• screenPickExtent - this balloon's screen-coordinate bounding rectangle, including area covered by the balloon's pickable outline.
• webViewRect - the WebView's screen-coordinate content frame.
• eyeDistance - always 0.

Specified by:

computeBalloonPoints in class AbstractBrowserBalloon

Parameters:

dc - the current draw context.

getScreenLocation

public Point getScreenLocation()

Get the position of the balloon on the screen.

Specified by:

getScreenLocation in interface ScreenBalloon

Returns:

The screen location of the balloon.

setScreenLocation

public void setScreenLocation(Point point)

Set the screen position of the balloon. This point is interpreted in a coordinate system with the origin at the upper left corner of the screen.

Specified by:

setScreenLocation in interface ScreenBalloon

Parameters:

point - Point in screen coordinates, with origin at upper left corner.

setupDepthTest

protected void setupDepthTest(DrawContext dc)

Specified by:

setupDepthTest in class AbstractBrowserBalloon
