public static String windowsUI = "com.sun.java.swing.plaf.windows.WindowsLookAndFeel";
try {     
UIManager.setLookAndFeel(windowsUI);     
UIDefaults def = UIManager.getDefaults();     
for (Enumeration e = def.keys(); e.hasMoreElements();)
{  String key = (String)e.nextElement();     
System.out.println(key+ ":"+def.get(key));
}catch (Exception ex)
System.out.println(ex);     
..........and i tried this also
try{
UIManager.setInstalledLookAndFeels(UIManager.getInstalledLookAndFeels());
          }catch(Exception e){System.out.println("Exception "+e);}

Answer 1

you are probably setting the LookAndFeel in the wrong spot in your code. You should set it every time your window reopens instead of just in the initialization.
