在这本书中，第二章中的对话框（findialog）实例，
void findNext(const QString &str,QT::CaseSensitivity cs);
void findPrevious(const QString &str,QT::CaseSensitivity cs);始终报错？
提示是
Multiple markers at this line
- `CaseSensitivity' has not been declared
- ISO C++ forbids declaration of `cs' with
no type
- `QT' has not been declared
没有声明吗？例子并没有说啊！
#ifndef FINDDIALOG_H
#define FINDDIALOG_H
