Any of those help i want to populate a gtk.notebook on-the-fly. everytime a user opens a file, a new notebook-tab is generated. pretty straight forward. my problem is, that i use glade to build the ui and the notebook-tab should have a child widget tree (scrolledwindow->viewport-> alignment->frame). in my glade-file, i have a template notebook-tab, which i want to use multiple times, so that i dont have to code the whole tree in plain gtk. with libglade, you could reuse a widget tree as explained in the pygtk faq here: http://faq.pygtk.org/index.py?file=faq22.011.htp&req=show . How do i do this with GtkBuilder? , Do it this way with GtkBuilder:
code :
builder = gtk.Builder()
builder.add_from_file("GUI.xml")
builder.connect_signals(self)
self.window1 = builder.get_object("window1")
self.window1.show()
builder.add_from_string("""
<interface>
  <object class="GtkWindow" id="window1">
    <child>
      <object class="GtkComboBox" id="combobox1">
        <property name="model">liststore1</property>
      </object>
    </child>
  </object>
</interface>""")

self.window1 = builder.get_object("window1")

Hope this helps Do you mean somethink along the lines of Label.set_text("new text")? If so, you probably first have to get the widget from the file using gtk.Builder.get_object("objectname").

help you fix your problem Thank to gpoo for helping me in figuring this out:
Make sure to read your error messages! I had a GtkNotebook with blank pages, which made the GtkBuilder complain. So no blank pages.

it helps some times You are using the wrong name for the property. In the documentation you can see that the property names are "width-request" and "height-request". This actually solved my problem, too.
