SWT編寫界面窗口時(shí)讓窗口處于屏幕中間
一、使用SWT本身
import org.eclipse.swt.graphics.Rectangle;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
public class LayoutUtil ...{
public static void centerShell(Display display,Shell shell)...{
Rectangle displayBounds = display.getPrimaryMonitor().getBounds();
Rectangle shellBounds = shell.getBounds();
int x = displayBounds.x + (displayBounds.width - shellBounds.width)>>1;
int y = displayBounds.y + (displayBounds.height - shellBounds.height)>>1;
shell.setLocation(x, y);
}
}
直接調(diào)用LayoutUtil.centerShell(Display display,Shell shell)即可使SWT窗口處于屏幕中央,其中,shell 要顯示的Shell對象。
二、借助AWT包里面獲取屏幕大小的方法
import java.awt.Toolkit;
/** *//**
* 在屏幕中間顯示Shell
* @param shell 要顯示的Shell對象
*/
private void centerShell(Shell shell)
...{
//得到屏幕的寬度和高度
int screenHeight = Toolkit.getDefaultToolkit().getScreenSize().height;
int screenWidth = Toolkit.getDefaultToolkit().getScreenSize().width;
//得到Shell窗口的寬度和高度
int shellHeight = shell.getBounds().height;
int shellWidth = shell.getBounds().width;
//如果窗口大小超過屏幕大小,讓窗口與屏幕等大
if(shellHeight > screenHeight)
shellHeight = screenHeight;
if(shellWidth > screenWidth)
shellWidth = screenWidth;
//讓窗口在屏幕中間顯示
shell.setLocation(( (screenWidth - shellWidth) / 2),((screenHeight - shellHeight) / 2) );
}
