Java JComponent paint --Almost working

Question

I almost have the repaint() Jcomponent working. I had it working and then tried to make an absolute positioning and now it doesn\'t work.

import java.awt.Col         


        

Answer 1

With Swing animation, the Timer class is an exceptional option.

//this class is a JPanel that implements ActionListener`
Timer t = new Timer(1000,this);//the first arg is how many times it repeats in milliseconds
//Then in the constructor...
t.start();
//the ActionPerformed function normally increments a variable then calls the repaint method.
rectangle_x++;
repaint(); //calls paintComponent 

Another good idea is to cast g to a Graphics2D object- it's a lot safer and more capable.
