按照书上写的程序，却总是出错，请教各位高人：

怎么回事啊？求助啊！

是不是和namespace有关系呢？

namespace怎么了啊？不懂唉

看不出来，不过错误提示说你那两个button没定义

class GoToCellDiaolog 里面的 是 GoToCellDiaolog
GoToCellDialog(QWidget *parent=0); 里面的是  GoToCellDialog

比较一下 GoToCellDiaolog 与 GoToCellDialog！！！
发现什么了，别出声哦。。。。

谢谢楼上的，真是慧眼啊，呵呵。
改完之后还是出错唉，为什么啊：：
gotocelldialog.cpp: In constructor `GoToCellDialog::GoToCellDialog(QWidget*)':
gotocelldialog.cpp:8: `clicked' undeclared (first use this function)
gotocelldialog.cpp:8: (Each undeclared identifier is reported only once for
   each function it appears in.)
gotocelldialog.cpp:8: `SINGAL' undeclared (first use this function)
gotocelldialog.cpp: In member function `void
   GoToCellDialog::on_lineEdit_textChanged()':
gotocelldialog.cpp:13: no matching function for call to `QPushButton::setEnable
   (bool)'
make: *** [gotocelldialog.o] Error 1

不都写的那么清楚了，自己要认真点看看编译出错的信息
比如gotocelldialog.cpp:8: `clicked' undeclared (first use this function)
你看你UI_GOTOCELL_H里面都没定义

SINGAL ->>>>>>>>>>>>SIGNAL。。。。

谢谢你们，弄好了，都是单词拼错了，以后小心点
