I made a GLADE file, a main window of type "GtkNotebook" and there are several pages in it (Window1 = Page1, Page2, Page3, Page4). 
a) Is it possible, like a web-browser, to take one of this page and separate it from the main windows? Example Page4 taken away with the cursor would create a Windows2
b) If not (I could not achieve it till now), I will have probably to create 2 windows which open automatically when I start my application (one will be Window1 = Page1, Page2, Page3, the second one will be Window2 with Page4). I will search how to do this after I have a feedback from here if a) could be done in any way.
Thanks (this is my first post here)
I think that is not posible to do dinamically.
As you know on Pygtk we load the glade file by this way wTree = gtk.glade.XML("localize.glade") only once time, and after that we have on scope the access to all tree of controls and componets.
If you have a window loaded, you can load another window, but not pull apart a tab that belong to a window loaded already, is something that not insted on pygtk, is not supported. Each window run on a singular process, i can not figure out how to pull apart it from the root proccess.
I hope its helps you out.
