repaint() in Java doesn't “re-paint” immediately?

Question

I have a code like that:

// In MyPanel.java
public void paintComponent(Graphics g)
{
    super.paintComponent(g);
    // Draw something
    mypanel_count++;
         


        

Answer 1

understand that you do not have complete control over if or when paint(...) get's called, and that repaint() calls are only a suggestion to the JVM to paint. If too many repaint() requests come in and they stack up as yours are doing, then they will be combined
