Java SWT 窗口居中对齐

public static void CentreWnd(Shell shell){ int width = shell.getMonitor().getClientArea().width; int height = shell.getMonitor().getClientArea().height; int x = shell.getSize().x; int y = shell.getSize().y; if (x > width) { shell.getSize().x = width; } if (y > height) { shell.getSize().y = height; } shell.setLocation((width - x) / 2, (height - y) / 2); }
