在QMainWindow中

dock4=QDockWidget(self.tr("停靠窗口4"),self)  
        dock4.setFeatures(QDockWidget.DockWidgetFloatable|QDockWidget.DockWidgetClosable)  
# 可引入外部Qwidget
widget4 = QWidget()  
dock4.setWidget(widget4)  
self.addDockWidget(Qt.RightDockWidgetArea,dock4)  


#多个QDockWidget，每两两停靠在一起可以实现多个QDockWidget的停靠在一起
#两个停靠窗口叠加
self.tabifyDockWidget(dock4, dock5) 
self.tabifyDockWidget(dock2, dock4)
