Hello!
I'm using a scrolled window widget inside a notebook page (the second page
of my notebook).
If I go to the second page, I see the scrolled window empty, and if I return
to the first notebook page again and add some elements, then I can see the
elements on the second page.
But, if I don't go to the second page BEFORE adding some elements to the
scrolled window, such elements are not shown.
When I go to the scrolled window page and return to the firsr page and add
some elements, the oldest and the newest are shown correctly.
This problem only happens once per execution of the program.
I send you a little snippet that has the problem too:
#!/usr/bin/python2.6
# -*- coding: utf-8; mode: python -*-
import gtk
import gobject
def add_to_tab2(btn, data=None):
global box
box.pack_start(gtk.Label('Something'))
box.pack_start(gtk.HSeparator())
box.show_all()
win = gtk.Window()
notebook = gtk.Notebook()
# Contained on first tab
btn = gtk.Button('Add to 2nd tab')
btn.connect('clicked', add_to_tab2)
# Contained on second tab
scroll = gtk.ScrolledWindow()
box = gtk.VBox()
scroll.add_with_viewport(box)
notebook.append_page(btn, gtk.Label('1st Tab'))
notebook.append_page(scroll, gtk.Label('2nd Tab'))
win.add(notebook)
win.show_all()
win.connect('destroy', gtk.main_quit)
gtk.main()
