TC的handler类调用swt窗口

public class SampleHandler extends AbstractHandler {
public Object execute(ExecutionEvent event) throws ExecutionException {
//方法一：新建一个application window的display类，在该类实现对话框功能，直接调用open（）
MyDisplay display = new MyDisplay();
display.start();
//方法二：创建一个shell，把实现了功能的对话框dialog加入shell
Shell shell = new Shell();
Dialog2 dialog = new Dialog2(shell, SWT.NONE);
dialog.open();
return null;
}
}
//给按钮添加一个鼠标监听事件，有两种方式实现：

方法一://      button.addListener(SWT.MouseUp, new MouseListener(text));//button.addListener(eventType, listener);//定义一个监听类，然后把自定义的监听类对象传给button的addListener(),enventType定义了button发生listener事件的条件。

class MouseListener implements Listener{

    private Text text;    public MouseListener(Text text)    {        this.text = text;    }    public void handleEvent(Event arg0) {        if(text.getText()==null)        {            MessageBox.post("please input folder-name", "提示:", MessageBox.ERROR);        }        else        {            TCSession session = (TCSession) AIFUtility.getDefaultSession();            TCComponentFolderType foldertype;            try {                InterfaceAIFComponent target = AIFUtility.getTargetComponent();                foldertype = (TCComponentFolderType) session.getTypeComponent("Folder");                TCComponentFolder folder = foldertype.create(text.getText(), "create a folder", "Folder");                if(target instanceof TCComponentFolder){                    ((TCComponentFolder) target).add("contents", folder);                }            }             catch (TCException e1)             {                e1.printStackTrace();            }        }    }}

//方法二：添加addMouseListener()监听事件，并定义mouseUp(event)执行的操作
button.addMouseListener(new MouseAdapter() {
@Override
public void mouseUp(MouseEvent e) {
if(text.getText()==null)
{
MessageBox.post(“please input folder-name”, “提示:”, MessageBox.ERROR);
}
else
{
TCSession session = (TCSession) AIFUtility.getDefaultSession();
TCComponentFolderType foldertype;
try
{
MessageBox.post(“please ….”, “提示：”, MessageBox.ERROR);
foldertype = (TCComponentFolderType) session.getTypeComponent(“Folder”);
TCComponentFolder folder = foldertype.create(text.getText(), “create a folder”, “Folder”);
}
catch (TCException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
}
});
FormData fd_button = new FormData();
fd_button.top = new FormAttachment(0, 5);
fd_button.left = new FormAttachment(0, 157);
button.setLayoutData(fd_button);
button.setText(“\u786E\u5B9A”);
