[Interest] QSettings watching for updates.

[Scott Aron Bloom]

That's my point...

 

QSettingsWatcher for windows would have to be a variant but non-portable
enhancement to QFileWatcher..

 

However, QSettingsWatcher for Linux could BE QFileWatcher, just pointing
to each file/directory.

 

For mac, Im not sure if it uses pfile or not, but again, pretty easy to
watch.

Yes, but that would not be portable. However you can force QSettings to
use another storage medium. (i.e. a file) which would be portable and
transparent.

Hoever, it would NOT be hard to extend FileSystemWatcher to handle
watching the registry.


Similar Win32 messages are emitted when the portion of the registry
changes and you are watching that portion..

I'd just suggest the QFileSystem watcher with a file (won't work with
Windows registry QSettings)

If "immediate notifications" are not a must, then "polling for changes"
might also be a possibility: re-loading the QSettings every n minutes
(or seconds).

Cheers, Oliver
