Re: Dashboard effect in Java application

cool!
:-)
On my pc, it works better with the following modifications.
The goal is to have a constant angular speed.
Also maybe you can use a SwingTimer instead of a thread ?

I read somewhere it's not safe to call awt/swing API outside the main thead,
but maybe it's ok for repaint().

thanks!

            public void run(){
                long t0 = System.currentTimeMillis();  //            
                while(true){                   
                    long t1 = System.currentTimeMillis(); //
                    angle += deltaAngle * (float)(t1-t0); // constant speed
                    t0 = t1;                  
                    if(((angle >= endAngle-deltaAngle/2) && (deltaAngle > 0)) ||
                       ((angle <= endAngle-deltaAngle/2) && (deltaAngle < 0))){
                        angle = endAngle;
                        if(Math.abs(angle - 360) < deltaAngle / 2) angle = 0;
                        if(Math.abs(angle - 180) < deltaAngle / 2) angle = 180;
                        repaint();
                        break;
                    }
                    if(angle >= 360) angle = 0;
                    if((int)angle % 90 == 0){
                        angle += deltaAngle;
                    }
                    try{
                        Thread.sleep(1000/30); // 30 FPS
                        repaint();
                        getToolkit().sync();
                    }catch(Throwable tt){
                    }
                }
