@HunterMcMillen Now for example after selecting the circle option circle will draw around pie menu. what i want is when user select the circle option and then click anywhere in the screen circle should draw there. — Mushahid Hussain, Apr 09 '12 at 15:59
*"anywhere in the screen"* Do you mean outside your application, or just in the 'drawing area' of the component? — Andrew Thompson, Apr 09 '12 at 17:11

Not sure how to make a shape exactly but a rectangle will help. Calculate the co-ordinates of each part of the pie chart and approximate it to a rectangle. For example, if the exit part in the pie chart is from (20,80), create a rectangle from (20,80) and width and height as 20 pixels.Create 9 rectangle objects like

Rectangle r1=new Rectangle(int startX,int startY,int width,int height);

And using mouseListener, you can easily check which rectangle is selected by using

public void mousePressed(MouseEvent me){
    if(r1.contains(me.getPoint){
         selected=1;
    }

Use the selected value in a switch case and implement the methods for whatever u want to.
