Qt - 如何在顶部而不是底部显示tabified dockwidget的选项卡

Question

在Qt中,您可以列出dockWidgets.如果我这样做,标签会显示在dockWidgets的底部,如左侧草图所示.这是我在Windows 7下使用最新的Qt4和PyQt4获得的行为.如何让Qt将标签放在dockWidgets顶部,如右图所示？

default: tabs on bottom                 I want: tabs on top
+--------------------+                  +------+-----+
| dockWidget1        |                  | tab1 | tab2|-------+
|                    |                  |                    |
| tab1 | tab2|-------|                  | dockWidget1        |
+------+-----+                          +--------------------+

Answer 1

你可以打电话

QMainWindow.setTabPosition (self, Qt.DockWidgetAreas areas, QTabWidget.TabPosition tabPosition)

(请注意,这适用于特定的停靠区域,这意味着您可以使用具有各种选项卡配置的不同停靠区域.)

使用枚举:Qt.DockWidgetAreas和QTabWidget.TabPosition:

#Qt.DockWidgetAreas
Constant                   Value
---------------------      -------
Qt.LeftDockWidgetArea       0x1
Qt.RightDockWidgetArea      0x2
Qt.TopDockWidgetArea        0x4
Qt.BottomDockWidgetArea     0x8
Qt.AllDockWidgetAreas       DockWidgetArea_Mask
Qt.NoDockWidgetArea         0


#QTabWidget.TabPosition
Constant          Value     Description
----------       -------    -----------
QTabWidget.North    0       The tabs are drawn above the pages.
QTabWidget.South    1       The tabs are drawn below the pages.
QTabWidget.West     2       The tabs are drawn to the left of the pages.
QTabWidget.East     3       The tabs are drawn to the right of the pages.

(参考:http://pyqt.sourceforge.net/Docs/PyQt4/qmainwindow.html#setTabPosition)

这是结果:
