实验一：线程通信：门铃实验时间： 实验地点： A603 一、实验目的1.熟悉QT的多线程编程2.学会使用QThread类创建线程3.掌握使用QT事件进行跨线程通信的方法二、实验内容1.使用QThread类和Qt事件跨线程通信配合完成一个门铃实验。2.门铃示例创建一个工作线程，随机发送门铃事件给GUI线程中的主人，事件中携带客人和礼物的信息，主人如果觉得客人和礼物都满意，就两眼放光，否则就假装不在。三、实验要求1.熟悉QT的多线程编程，了解Qt事件跨线程通信的方法四、实验步骤1.使用QT应用程序向导创建GUI工程2.使用QT Designer设计图形用户界面 拖曳控件 调整布局 设置属性 信号与槽映射3.使用QT Create编写代码4.编译5.构建6.调试五、实验源码main.cpp#include doorbell.h#include int main(int argc, char *argv) QApplication a(argc, argv); Master w; w.show(); return
