1、普通模式，如图

 1 /* 向在移动 */
 2 QTabWidget::tab-bar {
 3     left:20px;
 4 }
 5 
 6 QTabBar::tab {
 7     background:qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
 8                     stop: 0 #E1E1E1, stop: 0.4 #DDDDDD,
 9                                    stop: 0.5 #D8D8D8, stop: 1.0 #D3D3D3);
10     border:2px solid #C4C4C3;
11     border-bottom-color:red;
12     border-top-left-radius:4px;
13     border-top-right-radius:4px;
14     min-8px;
15     padding:2px;
16 }
17 
18 /* 标签被选中时或鼠标悬浮时 */
19 QTabBar::tab:selected,QTabBar::tab:hover {
20     background:qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
21                                 stop: 0 #fafafa, stop: 0.4 #f4f4f4,
22                                 stop: 0.5 #e7e7e7, stop: 1.0 #fafafa);
23 }
24 
25 /* 标签被选中时 */
26 QTabBar::tab:selected {
27     border-color:#9B9B9B;
28     border-bottom-color:#C2C7CB;
29 }
30 
31 /* 标签未被选中时 */
32 QTabBar::tab:!selected {
33     margin-top:2px;
34 }

2、被选中的标签，外框扩大，如图

 1 QTabWidget::pane {
 2     border:4px solid #C3C7CB;
 3 }
 4 
 5 QTabWidget::tab-bar {
 6     left:20px;
 7 }
 8 
 9 /* 标签外形设置 */
10 QTabBar::tab {
11     background:qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
12                                 stop: 0 #E1E1E1, stop: 0.4 #DDDDDD,
13                                 stop: 0.5 #D8D8D8, stop: 1.0 #D3D3D3);
14     border:2px solid #C4C4C3;
15     border-bottom-color:#C2C7CB;
16     border-top-left-radius:4px;
17     border-top-right-radius:4px;
18     min-50px;
19     padding:2px;
20 }
21 
22 /* 标签被选中时或鼠标悬浮时 */
23 QTabBar::tab:selected,QTabBar::tab:hover {
24     background:qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
25                                 stop: 0 #fafafa, stop: 0.4 #f4f4f4,
26                                 stop: 0.5 #e7e7e7, stop: 1.0 #fafafa);
27 }
28 
29 /* 标签被选中时 */
30 QTabBar::tab:selected {
31     border-color:#9B9B9B;
32     border-bottom-color:#C2C7CB;
33 }
34 
35 /* 标签未被选中时 */
36 QTabBar::tab:!selected {
37     margin-top:2px;
38 }
39 
40 /* 标签被选中时,外框向外扩大 */
41 QTabBar::tab:selected {
42     margin-left:-4px;
43     margin-right:-4px;
44 }
45 
46 /* 最左边的标签被选中时,外框不变化 */
47 QTabBar::tab:first:selected {
48     margin-left:0px;
49 }
50 
51 /* 最右边的标签被选中时,外框不变化 */
52 QTabBar::tab:last:selected {
53     margin-right:0;
54 }

3、标签居中，如图

 1 /* 把显示界面向上移动 */
 2 QTabWidget::pane {
 3     border-top:2px solid #C2C7CB;
 4     position:absolute;
 5     top:-10px;
 6 }
 7 
 8 /* 标签居中 */
 9 QTabWidget::tab-bar {
10     alignment:center;
11 }
12 
13 QTabBar::tab {
14     background:qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
15                                 stop: 0 #E1E1E1, stop: 0.4 #DDDDDD,
16                                 stop: 0.5 #D8D8D8, stop: 1.0 #D3D3D3);
17     border:2px solid #C4C4C3;
18     border-bottom-color:#C2C7CB;
19     border-top-left-radius:4px;
20     border-top-right-radius:4px;
21     min-20px;
22     padding:2px;
23 }
24 
25 QTabBar::tab:selected,QTabBar::tab:hover {
26     background:qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
27                                 stop: 0 #fafafa, stop: 0.4 #f4f4f4,
28                                 stop: 0.5 #e7e7e7, stop: 1.0 #fafafa);
29 }

31 QTabBar::tab:selected {
32     border-color:#9B9B9B;
33     border-bottom-color:#C2C7CB;
