/*jface常用对话框
* ErrorDialog--可根据错误级别来显示错误消息,一般用于eclipse工作台
* MessageDialog--可显示提示消息的对话框,类似于SWT的对话框,但比SWT功能强大,是最常用的对话框
* ProcessMonitorDialog--可以显示后台线程进度的对话框
* InputDialog--用于输入消息的对话框,同时可以验证用户输入,并可以将验证的消息显示在对话框中
* PreferenceDialog--专门为设置首选项所使用的对话框,
* TitleAreaDialog--带有标题,图表和描述信息的对话框
* WizardDialg--向导式对话框,用于将一个操作分为几页来显示的对话框.

* setTitle(String newTitle)设置提示信息标题.
* setTitle(RGB color);设置标题区域的颜色
