file parsing/watching + qt

[aljosa]

this is a Qt app. app should watch for changes in /var/log/isdn.log and
on file change (like new line was added to isdn.log) it should activate
event in my app.

i'm trying to fetch last line in file whenever isdnlog logs something
so that i can parse that line for a number and store it somewhere else,
is there a standard solution for this?

i'm using python2.3 on linux with PyQt3.
