突然发现,原来不做第4步程序也能正常
编译运行,而且点击之后居然能够正确
执行槽函数!
难道Qt
Creator 2.2.1已经如此智能了吗……
---------------------------------------------------------------------------
我都是如下操作,但是总会有warning
1.qt creator添加菜单action
2.在.h中添加private slots声明
void on_action_triggered(bool b);
3.在.cpp实现on_action_triggered(bool b){}
4.在.cpp添加connect(ui->action, SIGNAL(triggered(bool)), this, SLOT(on_action_triggered(bool b)));
然后编译运行程序总是在控制台提示
Object::connect: No such slot MainWindow::on_action_triggered(bool b)
Object::connect: (sender name: 'action')
Object::connect: (receiver name: 'MainWindow')
但是运行又一切正常……
我的操作哪里有
问题吗?
