Please look at my layout.

I modified my code, but why enent listener are not working?

Thanks

Thank you much. You are so patient. I am reading you code and try to understand. And I will modigy my code as your model. Now, could you

mind look at my current code? It still can't add on the drawing.Unfortunty I have no data file, my original data file is a binary format.

okay, I still have some questions.

1) I try to rotate my drawing. It doesn't work after I add one statement though.

public void paintComponent(Graphics g)

{

super.paintComponent( g ); // call superclass's paint method

this.setBackground( Color.WHITE );

Graphics2D g2d = (Graphics2D)g; // cast g to Graphics 2D

g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,RenderingHints.VALUE_ANTIALIAS_ON);

getDrawingData();

if (a==0)

drawPolygon(g2d);

drawSides(g2d);

g2d.rotate(Math.PI/8.0);// here not working

2) I found in my applet a small part is cut off at the bottom in my painting. why?

3). I see in your example applying with AffineTransform. In my case I will draw many lines without defining an object. So how can I implement it?

public void drawSides(Graphics2D g2d)

{

g2d.setColor(Color.GRAY);

g2d.setStroke(new BasicStroke((float)lineWidth));

for (int i = 0; i<numberofCells; i++)

{

for (int j = 0; j><cellsPointsNumber[i]-1; j++)

{

x1 = xCells[i][j];

y1 = yCells[i][j];

x2 = xCells[i][j+1];

y2 = yCells[i][j+1];

Line2D line = new Line2D.Double(x1,y1,x2,y2);

g2d.draw(line);// draw Sides here

}

}

}

Thanks again,>
