any interactions on it, see the AShape Tutorial for information

on how to do this.

If all we want to do is fill blue rectangles there is a faster

way, the #2 in the list above. It might be used to paint a

great number of read only activities with extreme speed.

// Setting a new renderer as defined below.

container.getDateArea().setActivityViewRenderer(new BlueRectangleRenderer());

// add outside a method declaration in your class

static class BlueRectangleRenderer implements ActivityViewRenderer

{

private final Insets REPAINT_MARGIN = new Insets(1, 1, 1, 1);

public void paint(Graphics2D g2, Rectangle bounds, TimeSpanList actViewList)

{

Paint oldPaint = g2.getPaint();

g2.setColor(Color.BLUE);

Rectangle clip = g2.getClipBounds();

for (int ix = 0, ixSz = actViewList.size(); ix < ixSz; ix++) {

ActivityView actView = (ActivityView) actViewList.get(ix);

Rectangle[] actBnds = actView.getBounds();

if (actBnds != null) {

for (int i = 0; i < actBnds.length; i++) {

Rectangle actBnd = actBnds[i];

if(actBnd != null && clip.intersects(actBnd)) {

g2.fill(actBnd); // The actual paint code! Exchange for something better...

}

g2.setPaint(oldPaint);

}

public Insets getRepaintMargin()

{

return REPAINT_MARGIN;

}

You now have the basics for changing the AShapes for you

own, and even for implementing you own proprietary paint

algorithm.

In the demo source that was installed with the component

you can look at AShapeCreator source code. It contains

some example AShapes.

Decorators

The Basics

You have already used a couple of decorators above, but
