java - Overriding paintComponent -

ok have been trying figure out past 26 hours guide , online no success.

all want draw oval when user clicks in paintpanel please can sleep :p

in paintapplet class:

  private void paintpanelmouseclicked(java.awt.event.mouseevent evt) {                                             // todo add handling code here:     if(fillradiobutton.isselected())     {     paintpanel.setbackground(jcolor.getcolor());    paintpanel.repaint();     }     if(brushradiobutton.isselected())     {          point componentpoint = paintpanel.getlocationonscreen();          paintpanel.add(new painter(componentpoint));     } }            

painter class:

import java.awt.color; import java.awt.dimension; import java.awt.graphics; import java.awt.graphics2d; import javax.swing.jframe; import javax.swing.jpanel;  import java.awt.*;  public class painter extends jpanel{  point  component;  public painter(point com) {     component = com; }  public void paintcomponent(graphics g)  {          super.paint(g);       point cursorpoint=   mouseinfo.getpointerinfo().getlocation(); //gets cursorpoint         int compx =  component.x;         int compy =  component.y;         int curpx =  cursorpoint.x;         int curpy =  cursorpoint.y;         int finalx = curpx - compx;         int finaly =  curpy - compy;         g.drawoval(finalx, finaly, 20, 20);     } } 

don't call

super.paint(g); 

within paintcomponent. result in infinite loop in paint chain mechanism. instead need

super.paintcomponent(g); 

for better sooner consider posting sscce
