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);
}
