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 = callbacks.Callbacks
class Callbacks:
def on_window_delete_event(widget, event, data=None):
return False
def on_button_highlight_clicked(widget, data=None):
glade_file = "main_window.glade"
glade_xml_tree = gtk.glade.XML(glade_file, "window")
textview = glade_xml_tree.get_widget("textview_code")
textbuffer = textview.get_buffer()
text = textbuffer.get_text(*textbuffer.get_bounds())
print text
textbuffer.set_text("next run")
def on_window_destroy(widget, data=None):
gtk.main_quit()
class CodeHighlighter:
def main(self):
gtk.main()
def __init__(self):
glade_file = "main_window.glade"
self.glade_xml_tree = gtk.glade.XML(glade_file, "window")
textview = self.glade_xml_tree.get_widget("textview_code")
print textview.get_buffer().get_text(*textview.get_buffer
().get_bounds())
dic = Callbacks.__dict__
self.glade_xml_tree.signal_autoconnect(dic)
window = self.glade_xml_tree.get_widget("window")
#window.connect("destroy", self.destroy)
#window = self.glade_xml_tree.get_widget("window")
window.show_all()
if __name__ == "__main__":
codehighlighter = CodeHighlighter()
codehighlighter.main()
