使用到的函数：

features : DockWidgetFeatures

This property holds whether the dock widget is movable, closable, and floatable.

By default, this property is set to a combination of DockWidgetClosable, DockWidgetMovable and DockWidgetFloatable.

Access functions:

DockWidgetFeatures	features() const
void	setFeatures(DockWidgetFeatures features)

Notifier signal:

void	featuresChanged(QDockWidget::DockWidgetFeatures features)

其中，DockWidgetFeature为：

enum QDockWidget::DockWidgetFeature
flags QDockWidget::DockWidgetFeatures

Constant Value Description

QDockWidget::DockWidgetClosable	0x01	The dock widget can be closed. On some systems the dock widget always has a close button when it's floating (for example on MacOS 10.5).
QDockWidget::DockWidgetMovable	0x02	The dock widget can be moved between docks by the user.
QDockWidget::DockWidgetFloatable	0x04	The dock widget can be detached from the main window, and floated as an independent window.
QDockWidget::DockWidgetVerticalTitleBar	0x08	The dock widget displays a vertical title bar on its left side. This can be used to increase the amount of vertical space in a QMainWindow.
QDockWidget::AllDockWidgetFeatures	DockWidgetClosable | DockWidgetMovable | DockWidgetFloatable	(Deprecated) The dock widget can be closed, moved, and floated. Since new features might be added in future releases, the look and behavior of dock widgets might change if you use this flag. Please specify individual flags instead.
QDockWidget::NoDockWidgetFeatures	0x00	The dock widget cannot be closed, moved, or floated.

allowedAreas : Qt::DockWidgetAreas

This property holds areas where the dock widget may be placed.

The default is Qt::AllDockWidgetAreas.

Access functions:

Qt::DockWidgetAreas	allowedAreas() const
void	setAllowedAreas(Qt::DockWidgetAreas areas)

Notifier signal:

void	allowedAreasChanged(Qt::DockWidgetAreas allowedAreas)

enum Qt::DockWidgetArea
flags Qt::DockWidgetAreas

Constant Value

Qt::LeftDockWidgetArea	0x1
Qt::RightDockWidgetArea	0x2
Qt::TopDockWidgetArea	0x4
Qt::BottomDockWidgetArea	0x8
Qt::AllDockWidgetAreas	DockWidgetArea_Mask
Qt::NoDockWidgetArea	0
