It is possible to use single text view widget, but you have to reparent
it on every notebook page change -- and this is not correct way.
The right solution is to create new text view for every file. So,
your code should look like this:

def __init__(self):
self.editors = []   # holds all textview widgets
...

def new_file(self,widget):
self.doc_num += 1
b = len(self.documents)

editor = gtk.TextView()
self.editors.append(editor)
self.tab_panel.append_page(editor, gtk.Label("ASD"))

Replace

self.tab_panel.append_page(self.editor, gtk.Label("ASD"))


with

self.tab_panel.append_page(gtk.TextView(), gtk.Label("ASD"))
self.tab_panel.show_all()

, then, fix the organization of the program in order to make it do what
you want.

[pygtk] Can't set a parent on widget which has a parent

2010-02-09 Thread Alexander Kuleshov 
Hello. I have following problem. Am writing a simple program with
pygtk. I have a window on it located menu, statusbar and NoteBook. The
tabs should be located NoteBook element GtkTextView. By clicking on
the menu, I must appear a new tab with GtkTextView. But I get the
following: Can't set a parent on widget which has a parent

What to do in this case?
