class MyWidget : public QWidget {Q_OBJECTpublic:MyWidget();signals:void mySignal();public slots:void mySlot();}; 在这个例子中,MyWidget类定义了一个信号mySignal和一个槽mySlot。 5.2 信号连接到槽 信号与槽之间的连接是动态的,意味着你可以在运行时将它们连接起来或者断开连接。
BaseClass* obj = new DerivedClass(); 这里,DerivedClass是BaseClass的一个子类。这种从父类到子类的转换是多态(Polymorphism)的一个基础概念。 2.2.2 代码生成 当你在Qt Designer中提升一个控件后,生成的UI代码会使用你指定的自定义类来创建该控件,而不是使用原始的基础类。

Finding a Qt class can be done with find-qt-class-name. It searches a static table of known Qt classes (*qt-class-map*) by first stripping all dashes from the name, and then case-insensitively finding a matching name. Translating method names can be done through to-method-name, which...
