eclipse插件教程-弹出界面框

package com.youhua.link.actions;

import org.eclipse.swt.SWT;
import org.eclipse.swt.graphics.Color;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;

public class Main {

  public static void main(String[] args) {
    // TODO Auto-generated method stub
    Display display = new Display();
    Shell shell = new Shell(display);
    
    shell.setText("hello");
    shell.setBounds(100,100,200,50);
    shell.setLayout(new FillLayout());
    
    Label label = new Label(shell,SWT.CENTER);
    label.setText("fd");
    
    Color red = new Color(display,255,0,0);
    label.setForeground(red);
    
    shell.open();
    
    while(!shell.isDisposed()){
      if(!display.readAndDispatch()){
        display.sleep();
      }
    }
    
    red.dispose();
    display.dispose();
    
  }

}

利用SWT组件，单独编写一个框，该弹框可以独立运行。
