Constructor Detail

PolygonRenderEvent

public PolygonRenderEvent(java.lang.Object oSource)
The constructor.

Method Detail

setPoints

public final void setPoints(Location[] la)
Sets the co-ordinates for each point that defines the polygon.


getPoints

public final Location[] getPoints()
Returns:
Returns the co-ordinates for each point in the polygon

getBackground

public Fill getBackground()
Overrides:
getBackground in class PrimitiveRenderEvent
Returns:
Returns the background fill attributes for the polygon

setBackground

public void setBackground(Fill ifBackground)
Sets the background fill attributes for the polygon


getOutline

public LineAttributes getOutline()
Returns:
Returns the polygon outline attributes.

setOutline

public void setOutline(LineAttributes lia)
Sets the polygon outline attributes


getBounds

public Bounds getBounds()
                 throws ChartException
Description copied from class: PrimitiveRenderEvent
Returns the mimimum bounds required to contain the rendering area for current event.

Overrides:
getBounds in class PrimitiveRenderEvent
Returns:
Throws:
ChartException - if not implemented by concrete class

copy

public PrimitiveRenderEvent copy()
Overrides:
copy in class PrimitiveRenderEvent
Returns:
A copy of this primitive rendering instruction implemented by subclasses

draw

public final void draw(IDeviceRenderer idr)
                throws ChartException
Description copied from class: PrimitiveRenderEvent
Causes this instruction to 'draw' itself on the device renderer

Overrides:
draw in class PrimitiveRenderEvent
Throws:
ChartException

fill

public final void fill(IDeviceRenderer idr)
                throws ChartException
Description copied from class: PrimitiveRenderEvent
Causes this instruction to 'fill' itself on the device renderer

Overrides:
fill in class PrimitiveRenderEvent
Throws:
ChartException

reset

public void reset()
Description copied from class: ChartEvent
Resets the inner state of current event. This must be implemented if the object is cached and reused.

Specified by:
reset in class ChartEvent

getLineAttributes

public LineAttributes getLineAttributes()
Overrides:
getLineAttributes in class PrimitiveRenderEvent
Returns:
A reference to the LineAttributes
