Method Detail
-
getPaint
public Paint getPaint()
Returns the paint used to fill the background.- Returns:
- The paint (never
null). - See Also:
setPaint(Paint)
-
setPaint
public void setPaint(Paint paint)
Sets the paint for the dial background and sends aDialLayerChangeEventto all registered listeners.- Parameters:
paint- the paint (nullnot permitted).- See Also:
getPaint()
-
getGradientPaintTransformer
public GradientPaintTransformer getGradientPaintTransformer()
Returns the transformer used to adjust the coordinates of anyGradientPaintinstance used for the background paint.- Returns:
- The transformer (never
null). - See Also:
setGradientPaintTransformer(GradientPaintTransformer)
-
setGradientPaintTransformer
public void setGradientPaintTransformer(GradientPaintTransformer t)
Sets the transformer used to adjust the coordinates of anyGradientPaintinstance used for the background paint, and sends aDialLayerChangeEventto all registered listeners.- Parameters:
t- the transformer (nullnot permitted).- See Also:
getGradientPaintTransformer()
-
isClippedToWindow
public boolean isClippedToWindow()
Returnstrueto indicate that this layer should be clipped within the dial window.- Specified by:
isClippedToWindowin interfaceDialLayer- Returns:
true.
-
draw
public void draw(Graphics2D g2, DialPlot plot, Rectangle2D frame, Rectangle2D view)
Draws the background to the specified graphics device. If the dial frame specifies a window, the clipping region will already have been set to this window before this method is called.
-

hashCode
public int hashCode()
Returns a hash code for this instance.- Overrides:
hashCodein classAbstractDialLayer- Returns:
- The hash code.
-
clone
public Object clone() throws CloneNotSupportedException
Returns a clone of this instance.- Specified by:
clonein interfacePublicCloneable- Overrides:
clonein classAbstractDialLayer- Returns:
- The clone.
- Throws:
CloneNotSupportedException- if some attribute of this instance cannot be cloned.
