All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

public class DrawFrontViewAntenna
extends javax.swing.JPanel

A panel that handles the display of the elevation position of the antenna. An image is used to represent the antenna itself, while Shape objects represent the angles of the various settings and positions. The display is updated regularly to keep a constant display of the antenna's current state.

Constructor Detail

DrawFrontViewAntenna

public DrawFrontViewAntenna()

The constructor for this class. Invokes the JPanel no-argument constructor.

Method Detail

paintComponent

public void paintComponent(java.awt.Graphics g)

Handles the setup and display of this antenna representation.

Overrides:

paintComponent in class javax.swing.JComponent

getAntennaImage

public java.awt.image.BufferedImage getAntennaImage()

Returns a BufferedImage object which represents the shape of the antenna from a forward-facing view. If the image file does not exist or can't be read, returns null

Returns:

the image representing this view of the antenna, if the file is successfully read; null otherwise.

updateImage

public void updateImage(double degree,
                        double posSSA,
                        double negSSA)

Sets the current antenna angle and soft stop positions in the display, and repaints the image. This method is called from the enclosing panel regularly to constantly display the current position of the antenna. All positions are measured in degrees.

Parameters:

degree - the angle, in degrees, of the current antenna position

posSSA - the angle, in degrees, of the positive soft stop

negSSA - the angle, in degrees, of the negative soft stop
