[Interest] QFileSystemModel expand indicator

[Sujan Dasmahapatra]

I have a QFileSystemModel which set to my QTreeView as model.  Somefolder
structure is present in the root. When some folder does not have any child
folder still the expand indicator(Triangle shape) is appearing left side.
How can I stop it not to appear if no folder is present. Any help is highly
appreciated.
