The .read() method in Python reads the whole file, not just the first
line.
read() will also read from the current position so you can keep reading
as new data is added. An alternative is to not open the file in
refreshLog but when initializing and then read it in refreshLog which is
called by timeout_add - something like:
Code:
textview = self.gui.get_widget("bottom_textview")
# Methods that need to be run on start
file = open('log.txt')
self.refreshLog()
# Timer to autorefresh log
timer = gobject.timeout_add(500, self.refreshLog)
timer.start()
def refreshLog(self):
string = file.read()
if string:
buffer = textview.get_buffer()
mark = buffer.create_mark("end", buffer.get_end_iter())
textview.scroll_to_mark(mark, 0)
buffer.insert_at_cursor(string)
buffer.delete_mark_by_name("end")
return True

Thank you all for the replies. I was not aware of the problems with the
threading in GTK+.
I got it working perfectly using the gobject timeout with Johns modified
routine. I now only have to insert new text from the log and dont have
to reread the whole thing.
Thanks!
