Add Item in QDIRMODEL + QTREEVIEW

[kamlmish]

Hi
I have a QDIRMODEL getting displayed in QTREEVIEW.
I am facing a issue where I need to create a shortcut link for the browsed directory and add it as a link to the treeview
I have created the shortcut link
using the QFILE ::LINK api
but am not able to add the link in the qdirmodel
The image for the flow is attached

1) Initial Page -mainwindow1
2) By pressing the "+" button , window2 comes up
3) By pressing the "browse" button, the treeview of the filesystem model comes
4) By pressing any item in the view, the name and location gets displayed , window4.png
5) Now by pressing the OK button , the directory that came above has to be aaded in the tree
