[Alessandro Crugnola *sephiroth*]

Hi,
i'm using wxPython and wxTextStyled.
How can I intercept document changes for active documents (for example modified with others external editors)?
thanks in advance

If you're on Linux (and perhaps other Unices) you can use FAM (file
alteration monitor). There's a Python library for the SGI version of
FAM (I don't know if it will work with anything other than XFS):

http://python-fam.sourceforge.net/

also check out this link:

If you're looking for a more general or cross-platform solution then
probably just periodically checking timestamp/size/md5sum for the file
is another (albeit somewhat less elegant) option.

Don't know if this is exactly what you're
after, but there are a couple of recipes
on the Cookbook:

This one deals with Linux:

and this one with Win32:

The MSDN docs on FindFirstChangeNotification
tell you which flags you need to use for
modification (as opposed to addition etc.):

thanks but that one check only new/deleted/renamed files (also useful indeed).
I should check also for modified files.. but I think i can add the functionallity to that script..

...but is not too stressing for the cpu to check for file changes in a (forever) while loop?
