TabWidget修改tab颜色，自定义样式

         可以通过tabWidget->setStyleSheet方法，设置样式，包括tab的样式。

          如

 QTabWidget* m_MainTab;
  m_MainTab->setStyleSheet("QTabWidget::pane{border-width:1px;border-color:rgb(96, 96, 96);\
                                    border-style: outset;background-color: rgb(96, 96, 96);} \
QTabWidget::tab-bar{border-width:0px;}\
QTabBar::tab{border-bottom-color: #FF0000;\
             border-top-left-radius: 0px;\
             border-top-right-radius: 0px;\
             min-width:100px; min-height:25px;\
             font:14px Times New Roman;\
                 padding: 0px;\
                 }\
QTabBar::tab:!selected {\
                        margin-top: 0px; margin-left: 30;\
                        border-image: url(:/images/tab/sel3.png);\
                    }\
QTabBar::tab:selected {\
                       color: blue;\
                           border-image: url(:/images/tab/sel3.png);\
                       }\
QTabBar::tab:hover:!selected {\
                              border-image: url(:/images/tab/sel3.png);\
                          }\
QTabBar::tab:selected {\
                       margin-left: 10;\
                   }");
