Detecting changes to file system for QFileSystemModel

[blackmarlin]

Hi,

I have a QFileSystemModel connected to a QTreeView. The items in the QFileSystemModel are checkable and I need to be able to correctly map the checked items to the corresponding location in the underlying file system. Now, what is a good way to detect if files and folders are added or removed from the directory structure monitored by the QFileSystemModel? I.e. are there any signals I can connect to in order to keep my mapping updated?

Ok. So I need to set up a separate QFileSystemWatcher for this, and can't indirectly or otherwise rely on the watcher used by the QFileSystemModel itself.

Thanks.

Since this is a model, you can connect to appropriate signals from QAbstractItemModel like rowsInserted().

That's what I was looking for. Thanks a lot.
