public class Balloons
extends ApplicationTemplate

Illustrates how to use a World Wind Balloon to display on-screen information to the user in the form of a screen-aligned text balloon. There are two abstract balloon types: ScreenBalloon which displays a balloon at a point on the screen, and GlobeBalloon which displays a balloon attached to a position on the Globe. For each abstract balloon type, there are two concrete types: AnnotationBalloon which provides support for simple text content with an optional image, and BrowserBalloon which provides support for complex HTML, JavaScript, and Flash content.

Balloon Content
A Balloon's content is specified by calling Balloon.setText(String), and its visual attributes are specified by calling Balloon.setAttributes(gov.nasa.worldwind.render.BalloonAttributes) with an instance of BalloonAttributes.

ScreenBalloon
ScreenBalloons display a screen-aligned balloon at a point on the screen. There are two concrete ScreenBalloon types:

• ScreenAnnotationBalloon - a screen-attached balloon with support for multi-line text, a background image, simple HTML text markup, and simple text styling attributes.
• ScreenBrowserBalloon - a screen-attached balloon with support for HTML, JavaScript, and Flash content.

GlobeBalloon
GlobeBalloons display a screen-aligned balloon attached to a position on the Globe.

• GlobeAnnotationBalloon - a Globe-attached balloon with support for multi-line text, a background image, simple HTML text markup, and simple text styling attributes.
• GlobeBrowserBalloon - a Globe-attached balloon with support for HTML, JavaScript, and Flash content.
