TC的handler類調用swt窗口

public class SampleHandler extends AbstractHandler {
public Object execute(ExecutionEvent event) throws ExecutionException {
//方法一：新建一個application window的display類，在該類實現對話框功能，直接調用open（）
MyDisplay display = new MyDisplay();
display.start();
//方法二：創建一個shell，把實現了功能的對話框dialog加入shell
Shell shell = new Shell();
Dialog2 dialog = new Dialog2(shell, SWT.NONE);
dialog.open();
return null;
}
}
//給按鈕添加一個鼠標監聽事件，有兩種方式實現：

方法一://      button.addListener(SWT.MouseUp, new MouseListener(text));
//button.addListener(eventType, listener);
//定義一個監聽類，然後把自定義的監聽類對象傳給button的addListener(),enventType定義了button發生listener事件的條件。

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()監聽事件，並定義mouseUp(event)執行的操作
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”);
