迟来的笔记，作为一个程序员每日记事已养成习惯，离开许久，不知不觉已喜欢用文字表达对技术的热爱，学无止境！
Qt – 一个跨平台应用程序和UI开发框架；它包括跨平台类库、集成开发工具和跨平台 IDE，使用 Qt 您只需一次性开发应用程序，无须重新编写源代码，便可跨不同桌面和嵌入式操作系统部署这些应用程序；深感强大的功能就是支持校本化和样式文件化，对于做web开发的同学能很快上手，强烈推荐。以下是Qt部分控件的样式写法例子，仅作参考，看着跟css3是不是很像。

如何应用以上Style到应用程序呢？
QString commonSkin = ResourceUtils::readAllText(":/skin/skin.css"); // 读取资源文件，文本格式
qApp->setStyleSheet(commonSkin); // 程序启动时，注册全局Style
效果图：
图一
图二
图一、二都是去掉标题栏的自定义不规则窗体，欢迎拍砖。。。
