how to draw oval using Graphics object

[usha]

Hi,


I have one requirement.I have drawn one oval on panel using Graphics2D object.
But i want to display the oval on panel immediately after executing the class with out performing any action(mouse click event). I had written the code in constructor.Its not displaying. This one working perfectly when i place the code on any event of the panel. please help me.

Thanks in advance,
Usha.

Perhaps you will want to reveal to us the libraries that you're using (Swing vs AWT), and to show us the code you've used so far, especially the one that's not working?

I used the following code. When i call this function from constructor its not working. Its working when i call this drawing function from mouse event of jPanel.



public class Example extends JFrame{
public Example(){
JPanel panel=new JPanel();
.....................................
..........................................
drawing();
}}




public void drawing(){
rd=(java.awt.Graphics2D)Panel.getGraphics();
RenderingHints rh = new RenderingHints(
RenderingHints.KEY_ANTIALIASING,
RenderingHints.VALUE_ANTIALIAS_ON);
rd.setRenderingHints(rh);
rd.drawOval(4,3,30,30);
rd.setColor(new java.awt.Color(83,125,249));
rd.fillOval(5,4,29,29);
rd.setColor(java.awt.Color.black);
rd.drawOval(p,q,7,7);
}

You apparently have not read the tutorials in the links the Darryl posted. I suggest you start there (as does he).
