QDockWidget类继承与QWidget类，用于停靠窗口的管理。在主窗口中，先设置中心控件，然后实例化QDockWidget对象，通过setFeatures( )设置停靠窗口的窗体特性，通过
setAllowedAreas( )设置窗体可停靠的区域。具体如下：
void setFeatures(DockWidgetFeatures features )
| QDockWidget::DockWidgetClosable |
停靠窗可关闭 |
| QDockWidget::DockWidgetMovable |
停靠窗可移动 |
| QDockWidget::DockWidgetFloatable |
停靠窗可浮动 |
| QDockWidget::DockWidgetVerticalTitleBar |
标题栏垂直放置 |
| QDockWidget::AllDockWidgetFeatures |
可关闭、可移动、可浮动 |
| QDockWidget::NoDockWidgetFeatures |
不可关闭、不可移动、不可浮动 |
void setAllowedAreas ( Qt::DockWidgetAreas areas )
| Qt::LeftDockWidgetArea |
可在中央控件的左侧停靠 |
| Qt::RightDockWidgetArea |
可在中央控件的右侧停靠 |
| Qt::TopDockWidgetArea |
可在中央控件的顶部停靠 |
| Qt::BottomDockWidgetArea |
可在中央控件的底部停靠 |
| Qt::AllDockWidgetAreas |
可在中央控件的任意方向停靠 |
| Qt::NoDockWidgetArea |
只可停靠在插入处 |
