Raise message dialog in TortoiseHg user interface

Question

I wrote a commit hook that works fine on the command line:

example.py

def saysomething(ui, repo, **kwargs):
    ui.status('today is 26-May')

I set up my repository .hg \ hgrc file to include:

[hooks]
commit = python:/path/to/example.py:saysomething

And when I take the command from the command line, I get the output "today is May 26th", as expected.

But I can not convince the TortoiseHg GUI to display a completion message. Am I using the wrong syntax in my python script? Do I need to add a hook to any configuration file other than the hgrc repository? I also tried adding a hook to the global .hgrc file, but that didn't help, and that would be a bad solution for my problem.

I looked at the HG tutorial on writing hooks , the tutorial on writing extensions, and the TortoiseHg tutorial, and I see nowhere to explain how to do this.

Using TortoiseHg 2.0.4, including Mercurial 1.8, on Windows XP.
