QSS 用法介绍
使用qt写程序，总要有界面，而美工给程序猿的设计总是那么美轮美奂，那么该怎么样将效果图转化为实际图？
qt借鉴css经验，设计出自己的qss。
拿实例说话吧：
1、
QPushButton#evilButton { background-color: red }
2、
QPushButton#evilButton {
background-color: red;
border-style: outset;
border-width: 2px;
border-color: beige;
}
3、
QPushButton#evilButton {
background-color: red;
border-style: outset;
border-width: 2px;
border-radius: 10px;
border-color: beige;
font: bold 14px;
min-width: 10em;
padding: 6px;
}
不知你看出区别了没有，也不知你看到他的用处没有。 如果没有那么这里一定有你想要的：
