QFileSystemWatcher::addPath recursively

Question

Hi all I want to use QFileSystemWatcher to watch changes of a given directory and its subdirectory recursively, but void QFileSystemWatcher::addPath ( const QString & path ) didn't let me do it so is there any idea to do it easily or I should implement it by my self (extract all directories and subdirectories and files under to added with void QFileSystemWatcher::addPaths ( const QStringList & paths ))?

Any help will be appreciated.

Thank you in advance.

Answer 1

The documentation of class QFileSystemWatcher doesn't state that recursive watching is part of its contract. So I think a solution might be, as you hinted, to walk the directory tree yourself, gather all sub-directories and their files in a string list and use

void QFileSystemWatcher::addPaths ( const QStringList & paths )

Also, I think it might be useful for you to mention which version of qt you are working with, because according to this thread, QFileSystemWatcher is being deprecated and a new api is supposed to replace it.
