当我编译运行后，在下面窗口有粉红色字显示（我用Qobject::connect(...)和conntct(....)和this->connect(...)都试过）
：如下
Starting E:\QT\untitled3-build-desktop-Qt_4_7_4_for_Desktop_-_MinGW_4_4__Qt_SDK__Debug\debug\untitled3.exe...

Object::connect: No such slot MainWindow::replyFinished(QNetworkReply *reply) in ..\untitled3\mainwindow.cpp:10 //我在头文件有声明slot函数啊

Object::connect: (receiver name: 'MainWindow')
