Moving undecorated window by clicking on JPanel

Question

Is there a possibility to move window by clicking on one of the panels in the window when that window is undecorated?

I have a main panel with matte border 40 pixels siz

Answer 1

int xMoved = (thisX + e.getX()) - (thisX + initialClick.x);

thisX + -thisX = 0

int xMoved = e.getX()-initialClick.x;

What i'm using.

public class MouseLiestenerX implements MouseListener,MouseMotionListener{

private theFrame;

public MouseLiestenerX(Frame theFrame){
this.theFrame = theFrame;

}

private Point startClick;

public void mouseDragged(MouseEvent e) {
    int deltaX = e.getX()-startClick.x;
    int deltaY = e.getY()-startClick.y;

    Core.getSp().setLocation(theFrame.getLocation().x+deltaX, theFrame.getLocation().y+deltaY);
}

public void mousePressed(MouseEvent e) {
    startClick = e.getPoint();
}

public void mouseMoved(MouseEvent e){

}
@Override
public void mouseClicked(MouseEvent e) {


}
@Override
public void mouseEntered(MouseEvent e) {
    // TODO Auto-generated method stub

}
@Override
public void mouseExited(MouseEvent e) {
    // TODO Auto-generated method stub

}
@Override
public void mouseReleased(MouseEvent e) {

}

}

and in your Frame constructor

MouseLiestenerX IMove = new MouseLiestenerX(this);      
addMouseListener(IMove);
addMouseMotionListener(IMove);
