QFileSystemModel update problem for shared network (samba) location

I'm using QFileSystemModel and QTreeView to display files tree from a shared network location (Samba).

Code:

---

Model->setRootPath("//HostName");
TreeView->setModel(Model);
TreeView->setRootIndex(Model->index("//HostName"));

---

The code works fine and I got the file tree. However, it can not automatically pick up the changes there. For example, if I create a new file there, the tree don't display this new file.

When I set the path to a directory on local hard drive, like "D:/temp". It works. It picks up the changes and update itself.

Any idea how can I pick up changes from a shared network location and refresh the model/tree?

You could trigger the refresh manually if you changed something on the fs (assuming to change comes not from "outside")

It doesn't work on networked file systems as it has no way of knowing when something has been changed. On a local file system, the OS will inform if something changes as all file i/o go through the OS.
