QTabWidget添加自定义样式

一、参考文章：http://bbs.csdn.net/topics/390632657?page=1

setStyleSheet("QTabWidget::pane{border-width:1px;border-color:rgb(48, 104, 151);\
                                    border-style: outset;background-color: rgb(132, 171, 208);\
                                    background: transparent;} \
QTabWidget::tab-bar{border-width:0px;}\
QTabBar::tab{border-bottom-color: #C2C7CB;\
             border-top-left-radius: 0px;\
             border-top-right-radius: 0px;\
             max-width: 75px; min-width:75px; min-height:25px;\
             font:14px Times New Roman;\
                 padding: 0px;\
                 }\
QTabBar::scroller {\
                   width:25;\
                       border:0;\
                           padding: 0px;\
                           }\
QTabBar QToolButton::right-arrow {\
                                  background-color:rgb(132, 171, 208);\
                                  border-width: 0;\
                                  background-image: url(:/images/tab/rightbtn.png);\
                              }\
QTabBar QToolButton::right-arrow:hover {\
                                        background-color:rgb(132, 171, 208);\
                                        border-width: 0;\
                                        background-image: url(:/images/tab/hoverrightbtn.png);\
                                    }\
QTabBar QToolButton::right-arrow:disabled {\
                                        background-color:rgb(132, 171, 208);\
                                        border-width: 0;\
                                        background-image: url(:/images/tab/grayrightbtn.png);\
                                    }\
QTabBar QToolButton::left-arrow {\
                                 background-color:rgb(132, 171, 208);\
                                 border-width: 0;\
                                 background-image: url(:/images/tab/leftbtn.png);\
                             }\
QTabBar QToolButton::left-arrow:hover {\
                                       background-color:rgb(132, 171, 208);\
                                       border-width: 0;\
                                       background-image: url(:/images/tab/hoverleftbtn.png);\
                                   }\
QTabBar QToolButton::left-arrow:disabled {\
                                       background-color:rgb(132, 171, 208);\
                                       border-width: 0;\
                                       background-image: url(:/images/tab/grayleftbtn.png);\
                                   }\
QTabBar::tab:first:selected {\
                             margin-left: 30; margin-right: 0;\
                             color: white;\
                                 border-image: url(:/images/tab/sel3.png);\
                             }\
QTabBar::tab:first:!selected {\
                              color: black;\
                                  margin-left: 30; margin-right: 0;\
                                  border-image: url(:/images/tab/normal3.png);\
                              }\
QTabBar::tab:first:hover:!selected {\
                                    color: black;\
                                        margin-left: 30; margin-right: 0;\
                                        border-image: url(:/images/tab/hover3.png);\
                                    }\
QTabBar::tab:middle:selected {\
                              margin-top: 0; margin-left: -15; margin-right: 8;\
                              color: white;\
                                  border-image: url(:/images/tab/sel3.png);\
                              }\
QTabBar::tab:middle:!selected {\
                               color: black;\
                                   margin-top: 0; margin-left: -15; margin-right: 8;\
                                   border-image: url(:/images/tab/normal3.png);\
                               }\
QTabBar::tab:middle:hover:!selected {\
                                     color: black;\
                                         margin-top: 0; margin-left: -15; margin-right: 8;\
                                         border-image: url(:/images/tab/hover3.png);\
                                     }\
QTabBar::tab:last:selected {\
                            margin-top: 0px; margin-left: 0; margin-right: 0;\
                            color: white;\
                                border-image: url();\
                            }\
QTabBar::tab:last:!selected {\
                             color: black;\
                                 margin-top: 0; margin-left: 0; margin-right: 0;\
                                 border-image: url();\
                             }\
QTabBar::tab:last:hover:!selected {\
                                   color: black;\
                                       margin-top: 0; margin-left: 0; margin-right: 0;\
                                       border-image: url();\
                                   }\
QTabBar::tab:only-one {\
                       margin: 0;\
                       }");
tab标签的长度，也需要重载QTabBar来动态计算。

二、设置QTabwidget的TabBar的样式1

QString tabBarStyle = "QTabBar::tab {min-width:100px;color: white;border: 2px solid;border-top-left-radius: 10px;border-top-right-radius: 10px;padding:5px;}\
QTabBar::tab:!selected {margin-top: 5px;} \
QTabBar::tab:selected {color: blue;}";
m_TabWidget->setStyleSheet(tabBarStyle);

三、设置QTabwidget的TabBar的样式2

QTabWidget::pane{

	border:none;

}

QTabWidget::tab-bar{

        alignment:left;

}

QTabBar::tab{

	background:transparent;

	color:white;

	min-width:30ex;

	min-height:10ex;

}

QTabBar::tab:hover{

	background:rgb(255, 255, 255, 100);

}

QTabBar::tab:selected{

	border-color: white;

	background:white;

	color:green;

}
