[pygtk] textbuffer doesn't change with entered text

[George Schneeloch]

Hey everybody. Basically my issue is that I have a TextView created in
glade, but the text in the TextBuffer of that textview doesn't change when I
enter something in the textbox. If it starts off blank, all get_text(*
textbuffer.get_bounds()) calls get an empty string, even if I have typed
something there. If I enter a default value in Glade, or if I call
textbuffer.set_text() beforehand, the get_text call returns that text no
matter what changes I make to the actual textbox. Any ideas what I'm doing
wrong?

Here's my code:
import pygtk
pygtk.require('2.0')
import gtk
import gtk.glade
import callbacks
#Callbacks =3D callbacks.Callbacks

class Callbacks:
    def on_window_delete_event(widget, event, data=3DNone):
        return False
    def on_button_highlight_clicked(widget, data=3DNone):
        glade_file =3D "main_window.glade"
        glade_xml_tree =3D gtk.glade.XML(glade_file, "window")

        textview =3D glade_xml_tree.get_widget("textview_code")
        textbuffer =3D textview.get_buffer()
        text =3D textbuffer.get_text(*textbuffer.get_bounds())
        print text
        textbuffer.set_text("next run")

    def on_window_destroy(widget, data=3DNone):
        gtk.main_quit()
class CodeHighlighter:
    def main(self):
        gtk.main()

    def __init__(self):
        glade_file =3D "main_window.glade"
        self.glade_xml_tree =3D gtk.glade.XML(glade_file, "window")
        textview =3D self.glade_xml_tree.get_widget("textview_code")
        print textview.get_buffer().get_text(*textview.get_buffer
().get_bounds())
        dic =3D Callbacks.__dict__
        self.glade_xml_tree.signal_autoconnect(dic)

        window =3D self.glade_xml_tree.get_widget("window")

        #window.connect("destroy", self.destroy)

        #window =3D self.glade_xml_tree.get_widget("window")

        window.show_all()

if __name__ =3D=3D "__main__":
    codehighlighter =3D CodeHighlighter()
    codehighlighter.main()
