我们编辑ui文件时候 可以这样使用槽函数, on_objectName_signal(args) ; 非常简便, 文档说明是下面
1 void QMetaObject::connectSlotsByName ( QObject * object ) [static] 2 Searches recursively for all child objects of the given object, and connects matching signals from them to slots of object that follow the following form: 3 4 void on_<object name>_<signal name>(<signal parameters>); 5 Let‘s assume our object has a child object of type QPushButton with the object name button1. The slot to catch the button‘s clicked() signal would be: 6 7 void on_button1_clicked();
尽管这里的button1是ui对象下的,它也是可以这样使用的,相当于系统自动建立好了连接。
它等同于在MainWindow。cpp中:connect(ui->button1, &QPushButton ::clicked, this, on_button1_clicked);
