eclipse SWT 界面屏幕中央位置

         int width = shlNewProjectWizard.getMonitor().getClientArea().width;int height = shlNewProjectWizard.getMonitor().getClientArea().height;int x = shlNewProjectWizard.getSize().x;int y = shlNewProjectWizard.getSize().y;if(x > width){shlNewProjectWizard.getSize().x = width;}if(y > height){shlNewProjectWizard.getSize().y = height;}shlNewProjectWizard.setLocation((width - x) / 2, (height - y) / 2);

是显示的界面位于屏幕的中央
