getWindow

public Shape getWindow(Rectangle2D frame)

Returns the shape for the window for this dial. Some dial layers will request that their drawing be clipped within this window.

getWindow in interface DialFrame

Parameters:

frame - the reference frame (null not permitted).

Returns:

The shape of the dial's window.

isClippedToWindow

public boolean isClippedToWindow()

Specified by:

isClippedToWindow in interface DialLayer

Returns:

A boolean.

draw

public void draw(Graphics2D g2,
 DialPlot plot,
 Rectangle2D frame,
 Rectangle2D view)

Draws the frame. This method is called by the DialPlot class, you shouldn't need to call it directly.

Specified by:

draw in interface DialLayer
