java swing undecorated moveable jframe form

 java swing undecorated moveable jframe form 

Ever since i have seen a key-gen , i was curious about how to make one in java.this is some of the progress along the way, the moveable yet no window controllers and play pause chip-tune music with transparent background.so far i have accomplished my task.

 

 AWTUtilities.setWindowOpacity(this, 0.8f); <- this is line responsible for windows transparency level.

 AWTUtilities.setWindowOpaque(this, false); <- this line is for controlling frames backgroung opaqe

moving the undecorated frame

                    if (DRAG_START == null) {
