I've finally found a work around.

It seems that the dirty() signal is not emitted (or is not "slotted")
if the process event has no time to process it.

Please look at the attachment, where I've added a unit test which proves th=
is.

In the testWatch() method, the code :

=09//Needed to be sure the signal will be emitted
=09QTest::qWait(1000);


could be commented to see that the signal being not emitted, even if
the file is modified.

I personally do not understand the real reason of this problem (but
the qWait() helps me to create my unit test, so everything is okay ;-)

To launch it :
cmake .
make
./dirwatcherTest

Regards.

Thanks again for your help Flavio.
