Continuous read of text from an input file

I'm looking for a way to continuously read text from a log file & to display in a widget. It continues to 'follow' the file. When additional lines are added to the file, they will be displayed on the widget for watching log files, or any other file which may be appended over time. Thanks.

Here's one way to do it: http://lists.trolltech.com/qt-intere...ad00066-0.html
