If closeActiveSubWindow() or closeAllSubWindows() won't work for you, 
you will have to write your own function that iterates over all the 
subwindow to find the one you want to close.

Or I could reach my goal(start the app with only one
> subwindow appears) through other better way?Any suggestions are welcomed.

You can write your app so that only one subwindow appears on startup. 
You can also write your app so that no subwindows appear on startup. 
Whether a subwindow is shown depends on whether you call show() on the 
object.
