top: -0.5em;
}

alignment: center;
}
/* Style the tab using the tab sub-control. Note that
it reads QTabBar _not_ QTabWidget */
QTabBar::tab {

border-top-right-radius: 4px;
min-width: 8ex;
padding: 2px;
}
QTabBar::tab:selected, QTabBar::tab:hover {
background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
stop: 0 #fafafa, stop: 0.4 #f4f4f4,
stop: 0.5 #e7e7e7, stop: 1.0 #fafafa);
}
QTabBar::tab:selected {
border-color: #9B9B9B;
border-bottom-color: #C2C7CB; /* same as pane color */
}奇怪的问题：
问题描述：
QTabWidget包含4各tab，每个里都有QLineEdit控件；因此采用如下的设置方式：
cpp
QLineEdit{
border - style: solid;
border - width: 0px 0px 1px 0px;
padding: 4px 4px 2px 4px;
border - color: #00BB9E;
background:none;
}结果：
-
在ui文件中StyleSheet中添加上述代码，生效；每个页面中的QLineEdit控件都执行；
-
使用QSS文件进行添加时，QTabWidget的首页和当前页中的QLineEdit控件不生效。
解决方法：
》在首页之前添加空白页；
》设置最后一页为当前页；
》删除添加的首页；
结论：
本文介绍了QTabWidget和QTabBar在进行样式设计时可设置的选项，并给出了几个示例，各位小伙伴可以自行选择！
