求助！关于构造函数 [复制链接]

本人将<<C＋＋ GUi Qt 4编程>>中的程序，在qdevolep中运行，结果就是出问题。我自己找半天实在找不出来，因为和原文对照着看，几乎是一样的。请各位兄台帮忙指出！
3Q！

问题就出在构造函数这几行，具体代码如下:
                       #include<QtGui>
                       #include "1.h"
              75    FindDialog::FindDialog(QWidget *parent)
              76              : QDialog(parent)
              77    {
                               lable=new QLable(tr("Find &What"));
                               lineedit=new LineEdit;
                                label->setBuddy (lineedit);
                                  ...
                         }

qdevolep编译出现的错误如下：

丢了个分号吧..................

lable=new QLable(tr("Find &What"),this);
lineedit=new LineEdit(this);

应该是这个了，楼主的头文件的类定义中估计忘记结尾的  分号 了

楼主不妨把头文件贴出来

回各位，本人自己检查了N编，确实没发现少分号之类的错误。崩溃中！
现将全部文件贴出，请各位帮忙看看。谢谢！
