Class FillWrapper

java.lang.Object
  jfig.objects.FillWrapper

public class FillWrapper

extends java.lang.Object

draw filled polygons via AWT 1.1 or Java2D (if available).

FillWrapper provides a wrapper for drawing of filled polygons for use by other FigObject objects.

Additionally, FillWrapper uses the timestamp information from the current viewport transformation and the last internal modification to decide whether a new world-coordinate -> screen-coordinate transformation is necessary.

If the FillWrapper constructor is called with 2 points only, then a rectangle with (left top) and (right bottom) coords is assumed. Otherwise a standard polygon is constructed.

Constructor Detail

FillWrapper

public FillWrapper(FigObject parent,
                   FigTrafo2D trafo,
                   java.awt.Point[] wcp)

basic FillWrapper constructor. This allocates the internal array with the screen-coordinates of the line points.

Parameters:

parent - The FigObject that uses this FillWrapper rectangle

trafo - The current editor viewport transformation, needed for the wc->sc coordinate transformation

wcp - The Point array with the (top left) and the (bottom right) corner for this rectangle in world coordinates

FillWrapper

public FillWrapper(FigObject parent,
                   FigTrafo2D trafo,
                   java.awt.Point[] wcp,
                   java.awt.Color extraColor)

special FillWrapper constructor used by FigArrow. This build the standard FillWrapper object but additionally sets extraColor to override the fillColor from the parent.attribs object.

This allows us to draw the arrowheads in the lineColor without need for an extra FigAttribs object.

Method Detail

getTimestamp

public long getTimestamp()

set_debug

public void set_debug()

activate debug output

get_scp

public java.awt.Point[] get_scp()

return the (up to date) screen coordinates.

Returns:

scp The Point[] array with the corners of this polygon in screen-coords.

buildSCP

public void buildSCP()

the transformation has changed. Recalculate the screen coords scp[]

paint

public void paint(java.awt.Graphics g)

paint(): Check whether we the viewport transformation has changed. If so, recalculate the wc -> wc transformation. Fill the polygon.

paintAWT11

public void paintAWT11(java.awt.Graphics g)
