SWT shell 窗体如何在桌面中央显示？

[lizzz]

Shell shell = new Shell();
shell.setSize(100, 100);
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);

BS一下楼上两位

	/**
	 * 设置窗口位于屏幕中间
	 * @param shell 要调整位置的窗口对象
	 */
	public static void center(Shell shell)
	{
		//获取屏幕高度和宽度
		int screenH = Toolkit.getDefaultToolkit().getScreenSize().height;
		int screenW = Toolkit.getDefaultToolkit().getScreenSize().width;
		//获取对象窗口高度和宽度
		int shellH = shell.getBounds().height;
		int shellW = shell.getBounds().width;
		
		//如果对象窗口高度超出屏幕高度，则强制其与屏幕等高
		if(shellH > screenH)
			shellH = screenH;
		
		//如果对象窗口宽度超出屏幕宽度，则强制其与屏幕等宽
		if(shellW > screenW)
			shellW = screenW;
		
		//定位对象窗口坐标
		shell.setLocation(((screenW - shellW) / 2), ((screenH - shellH) / 2));
	}
	
	/**
	 * 设置窗口位于屏幕中间
	 * @param display 设备
	 * @param shell 要调整位置的窗口对象
	 */
	public static void center(Display display, Shell shell)
    {
        Rectangle bounds = display.getPrimaryMonitor().getBounds();
        Rectangle rect = shell.getBounds();
        int x = bounds.x + (bounds.width - rect.width) / 2;
        int y = bounds.y + (bounds.height - rect.height) / 2;
        shell.setLocation(x, y);
    }

Frame2 f = new Frame2();
f.setSize(550,200);
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Dimension size = f.getSize();
int x = (screenSize.width - size.width) / 2;
int y = (screenSize.height - size.height) / 2;
f.setLocation( x, y );
f.setVisible(true);

[keyboardsun]

Frame2 f = new Frame2();

f.setLocationRelativeTo(null);

这是最简单的，保证绝对居中对齐，效率最高

为什么不直接new 一个居中的shell呢？
final Shell shell = new Shell(SWT.CENTER);
.....

哎，已经有的东西非要自己写一遍，还是6楼的最干脆
