I want a Qt window to come up with the following arrangement of dock widgets on the right.

Qt allows you to provide an argument to the addDockWidget method of QMainWindow to specify the position (top, bottom, left or right) but apparently not how two QDockWidgets placed on the same side will be arranged.
Here is the code that adds the dock widgets. this uses PyQt4 but it should be the same for Qt with C++
self.memUseGraph = mem_use_widget(self)
self.memUseDock = QDockWidget("Memory Usage")
self.memUseDock.setObjectName("Memory Usage")
self.memUseDock.setWidget(self.memUseGraph)
self.addDockWidget(Qt.DockWidgetArea(Qt.RightDockWidgetArea),self.memUseDock)
self.diskUsageGraph = disk_usage_widget(self)
self.diskUsageDock = QDockWidget("Disk Usage")
self.diskUsageDock.setObjectName("Disk Usage")
self.diskUsageDock.setWidget(self.diskUsageGraph)
self.addDockWidget(Qt.DockWidgetArea(Qt.RightDockWidgetArea),self.diskUsageDock)
When this code is used to add both of them to the right side, one is above the other, not like the screen shot I made. The way I made that shot was to drag them there with the mouse after starting the program, but I need it to start that way.
I never tried it but I think you can set the orientation of the dock widget when adding it to the main window:
