Inotify_add_watch error when deleting in Qt but not command line

I have a GUI that allows the user to delete items from a tree view that is also a file explorer (based on the tutorial from the Create GUI Applications book).

The user is able to create a project and various assets within that project. If the assets and project are compiled, using make, and then the project is deleted, I receive the following error:

inotify_add_watch("/home/user/User_OpenCPI_Projects/Blah") failed: "No such file or directory"
inotify_add_watch("/home/user/User_OpenCPI_Projects/Blah/components") failed: "No such file or directory"
inotify_add_watch("/home/user/User_OpenCPI_Projects/Blah/components/Gross") failed: "No such file or directory"

However, when the same process if performed via command line, the inotify errors do not appear, leading me to believe the main problem is in how Qt handles the deletion.

Any thoughts?
