■ QTabBar

#基本样式设置
QTabBar::tab{
    font: 75 12pt "Arial";        #设置字体
    width:84px;                    #设置宽度
    height:30;                     #设置高度
    margin-top:5px;             #设置边距
    margin-right:1px;
    margin-left:1px;
    margin-bottom:0px;
}

#最左边标签未选中时显示（因为需要左边打圆角，所以和其他背景图片不一样，注意字体颜色）
QTabBar::tab:first:!selected {
    color:#000000;
    border-image: url(:/common/images/common/左_normal.png);
}
#最左边标签被选中
QTabBar::tab:first:selected {
    color:#FFFFFF;
    border-image: url(:/common/images/common/左_pressed.png);
}
#最右边标签未选中时显示（因为需要右边打圆角，所以和其他背景图片不一样）
QTabBar::tab:last:!selected {
    color:#000000;
    border-image: url(:/common/images/common/右_normal.png);
}
#最右边标签被选中
QTabBar::tab:last:selected {
    color:#FFFFFF;
    border-image: url(:/common/images/common/右_pressed.png);
}
#中间的标签未被选择的显示
QTabBar::tab:!selected {
    color:#000000;
    border-image: url(:/common/images/common/中_normal.png);
}
#中间标签选中显示的图片
QTabBar::tab:selected {
    color:#FFFFFF;
    border-image: url(:/common/images/common/中_pressed.png);
}


tab标签居中显示
QTabWidget::tab-bar { 
    alignment: center; 
} 


5 鼠标停留tab标签的效果
鼠标放在标签上，可设置标签颜色或者背景图片
QTabBar::tab:hover{
    background:rgb(255, 255, 255, 100);
}
6 去掉tabwidget的widget边框
QTabWidget::pane{
    border:none;
}



QTabBar::tab{
    background-color: rgb(255, 255, 255);
}

QTabBar::tab:hover{
    background:rgb(46, 207, 38, 100);
}

QTabBar::tab:selected {
    background:rgb(25, 34, 231, 100);
}

QTabWidget:pane{ 
   border: 1px solid red; 
    top: -1px;
    background-color:grey;
}

QTabBar::tab{
    height:22px; background-color:grey; margin-right: 2px; margin-bottom:-2px;
}

QTabBar::tab:selected{
    border:1px solid red;border-bottom-color: none;
}

QTabBar::tab:!selected{
    border-bottom: 3px solid red;
}

■ QScrollBar

 /* 实例化垂直滚动条及设置位置大小 */
    verticalScrollBar = new QScrollBar(Qt::Vertical, this);
    verticalScrollBar->setGeometry(770, 0, 30, 480);

    /* 实例化，标签文本 */
    label = new QLabel(this);
    /* 设置文本 */
    label->setText("这是一个测试");
    /* 设置位置大小 */
    label->setGeometry(300, 200, 100, 20);这里插入代码片
