this.dispose();

this will close the default window is there any method to do that..keep default window open and goes back like a shade, a panel come forword

Answer 1

Dont use .dispose() you only need to hide it.Use

.setVisible(false);

If you want to make it faded out you have to animate it.Use jDialog instead.And play a bit with opacity.Bud in that case dont put set visible to False.Or you wont see it at all.

On new component which you want to have over it

.setAlwaysOnTop(true); // this makes sure that you will see it on top of your main window

after you are done put it away with dispose if you dont need it afterwards.
