AWT Window Opacity Fadeout

[Isaac Hewitt]

The code to fade out my JDialog works alright on one computer but not at all on the other even though both computers have Windows 7 and the latest version of Java.

    private void slowDisappearWindowAction(JDialog source, int milisSlow, int milisFast) throws InterruptedException {
        
    float level = 1.0f;
    
    for(int i = 0; i < 8 ; i++) {
        
        level = level - 0.05f;
        
        AWTUtilities.setWindowOpacity(source, level);
        
        Thread.sleep(milisSlow);
    }
  
    for(int i = 0; i < 8 ; i++) {
        
        level = level - 0.05f;
        
        AWTUtilities.setWindowOpacity(source, level);
        
        Thread.sleep(milisFast);
    } 
    
    AWTUtilities.setWindowOpacity(source, 0.1f);
}

- in Java7 were removed almost of thread safe (up to Java7) methods in API,

- usage of Thread.sleep(int) isn't about good practicies in Java

- Thread.sleep(int) freeze AWT/Swing untill sleep ended, all event are lost during this sleep, more in Oracle tutorial Concurency in Swing

- use Swing Timer in AWT, Swing exclusivelly
