我觉得Qt编程主要是对C++的理解。如果你会C++Qt编程不再话下,只要你掌握信号、槽等概念就可以了。本文 给出一个qt编程的基本流程(经典的hello实例),以此能快速上手qt编程。

1.生成一个工程文件 progen -t app.t -o hello.pro

2.通过Qt Designer设计界面,保存为hello.ui

3.生成窗体类的头文件和实现文件:

uic -o hello.h hello.ui (hello.h定义类,手动添加一些信号、槽、成员函数、成员数据)

uic -o hello.cpp -impl hello.h hello.ui(hello.cpp定义类中的信号、槽和成员函数的具体实现)

4.编写主函数main(),固定格式。

5.编辑工程文件hello.pro文件,相应位置加入相应文件,固定格式。

6.生成Makefile文件,在LIBS后加“-lm -stdc++”

7.编译连接整个工程并运行

make

qvfb & ./hello &
