this 指针只能在类里面用.你在main 函数里面用当然会报错啦...!

Member Function Index 页面列出了所有Qt类,每一个链接到它所在的类所提供的功能。 无论身在Qt参考文档中的何处,你会发现大量的交叉引用。示例代码甚至片段中包含可点击的链接,因此,例如:如果你在代码示例中遇到一个类声明,类名称将是一个类文档的可点击链接。
现在我们可以轻松地分辨operator []的左值与右值运用了,但当然这也是有的弊端的,原先我们使用v1[1]的方式取出来的就是原始数据类型,比如QVector<int>,我们可以对v1[1]使用+,-,++,--,等等操作符,如果是QVector<MyClass>还可以调用我们自己定义的member function。但是我们一旦开始使用代理类,如果你不同意,编译...
