How to overlay icons for a dir/file using Qt ?

[rawfool]

How can I achieve svn like folder/file overlays ?
I want to change the icons of the overlays as the corresponding directory/file(s) are modified. I'm watching the directory using inotify, so any change in the file(s)/sub-directorie(s) of the watch directory shall give me a signal and based on the signal I need to update the relevant icon to the views in the directory.

Thank you.

Update:
Something like in the pic shown below -

Well, how do you currently achieve the base visualization?

QListView and a model?

I'm not having any widgets, I'm into the window given by the corresponding OS(target might be any Linux distro).
I'm watching a directory using inotify and I'm getting signals about any activity in the watch directory. So, in a given window manager for any OS, is there any way I can overlay icons in the watch directory like svn does ?
Thank you.

That depends on the target program, i.e. how it plugin architecture looks like (if it has one) and what those plugins can do.

Since there are no Qt APIs as such, I learnt that, I need to use the corresponding file manager specific APIs.
So I'm starting to try with GNOME's nautilus file manager. I understood that I need to use nautilus_file_info_add_emblem() and other APIs in nautilus-file-info. But I'm unable to find how & which lib should I add in my Qt project to access nautilus file manager APIs ?

Link: nautilus-file-info (https://developer.gnome.org/libnautilus-extension/stable/libnautilus-extension-nautilus-file-info.html)

Kindly help me. Thank you.

You'll have to ask on a GNOME forum. There is likely a Nautilus plugin library
