[PyQt] QDockwidget advice needed

[danny]

thanks Pete,

I think you have answered my question. I am not supposed to manage the dock 
window as a tree item viewer, but rather as a tree viewer, just like any other.
In other words it is another view of the tree that only happens to show details
of one node at a time. That way the signals and slots can be set up once.  

I presume I do need an update UI function whenever the selected item changes, but
that is no big deal.

thanks,
Danny
