       Java代码   
timeButton.addActionListener(new ActionListener() {  
            @Override  
            public void actionPerformed(ActionEvent e) {  
                if(!startButton.isEnabled()){  
                    GUIUtil23.warningDialog("[启动]按钮不可用");  
                    return;  
                }  
                String delayStr=delayTextField.getText();  
                if(!DialogUtil.verifyTFEmpty(delayTextField, "定时启动时间")){  
                    return;  
                }  
                if(!ValueWidget.isInteger(delayStr)){  
                    GUIUtil23.warningDialog("定时启动的时间必须是数字[秒]");  
                    return;  
                }  
                final int secondDelay=Integer.parseInt(delayStr);  
                new Thread(new Runnable() {  
                    @Override  
                    public void run() {  
                        if(!validate22()){  
                            return;  
                        }  
                        try {  
                            timeButton.setEnabled(false);  
                            delayTextField.setEditable(false);  
                            Thread.sleep(secondDelay*1000);//单位是毫秒  
                            startConnect();  
                            timeButton.setEnabled(true);  
                            delayTextField.setEditable(true);  
                        } catch (InterruptedException e) {  
                            e.printStackTrace();  
                        }  
                    }
