Usage

From source file:Main.java

public static Point getScreenCenterLocation(Window w) {
    Dimension size = w.getSize();
    Toolkit toolkit = Toolkit.getDefaultToolkit();
    double desktopHeight = toolkit.getScreenSize().getHeight();
    double desktopWidth = toolkit.getScreenSize().getWidth();

    // To the left (hack for Ngoc's dual display)
    if (desktopWidth > 1600) {
        desktopWidth += 1600;//from   w  ww . j  ava  2 s . com
    }
    Point location = new Point();
    location.x = (int) (desktopWidth - size.getWidth()) / 2;
    location.y = (int) (desktopHeight - size.getHeight()) / 2;
    return location;
