内容:
才准备学QT，但是第一个程序就卡住了……（《24小时学通QT》中的第一个例子）
#include
#include
#include
int main(int argc,char **argv)
{
QApplication a(argc,argv);
QWidget mainwindow;
mainwindow.setMinimumSize(200,100);
mainwindow.setMaxmumSize(200,100);
QPushButton helloworld("Hello World!",&mainwindow);
helloworld.setGeometry(20,20,160,60);
a.setMainWidget(&mainwindow);
mianwindow.show();
return a.exec();
}
之后qmake -project
qmake都没事
make之后提示：
# make

src/h.cpp:37: error: `mianwindow' undeclared (first use this function)
src/h.cpp:37: error: (Each undeclared identifier is reported only once for each function it appears in.)
make: *** 错误 1

我使用的是magiclinux（一个很优秀的国人制作的社区发行版）自带的qt3.3，《24小时学通qt》中是以qt2作为讲解的，是不是因为版本变化的原因导致一些类发生了变化所以不行？？那么各位老大们能推荐几本适合初学者的qt3的中文书籍么？？在下英文不好……
多谢各位

这不是人家编译器都告诉过你了么？QWidget类里没有setMaxmumSize(应该是setMaximumSizze，你拼写错了), mianwindow没有被声明过（是mainwindow，你又拼写错了）
。。。。。。。。。。。。。。。
你说该怎么说你？

啊，抱歉……
在linux下看超星的电子书看的头都晕了……
多谢多谢
不过有什么qt3的书么》？？？
现在变成这样子了……

老大,你看的这本书是不是基于KDE的啊?
你写的东东用到了KDE的系统函数库,你没有在KDE环境下,当然会报错了!!!!!!!!!
