Never thought of that one!

Easier is to: "catch tixFileEntry"

Yes, but I don't see an easy way of doing it. I'll look further.

Tix now has a home where these kinds of things can be discussed:

	http://tix.sourceforge.net

All of the code is now under CVS which was a crucial step.
The documentation has been brought up to date, all the patches have been
collected and applied, and we're almost finished bringing the code up to
8.[0123] compatability.

There's a survey for what features people want to drop from Tix:
https://sourceforge.net/survey/?group_id=5649

Maybe we can use the Forums as a place to post requests for enhancements:
https://sourceforge.net/forum/?group_id=5649

If you have patches to provide new features, you can submit context diffs:
https://sourceforge.net/patch/?group_id=5649

This was Tix can be kept alive as far as feature growth.

Mike.
