custom file tree

[dinnot]

Hello.

I want to do a File Tree (like QTreeView does) but i want it to be custom. First it dont have any file, but when a file or a dir drops on it i want it to be added to root. Also, if the user want to delete one file from one dir that he added, he must be able to (oc without deleting the original file) and keeping the rest of files.

Example:
initialy:

<root>

<root>

To copy to clipboard, switch view to plain text mode 

//add directory "test" which contains file1, file2 and dir1 (which also contains file3)

<root>
- test
  file1
  file2
  - dir1
    file3

<root>
- test
  file1
  file2
  - dir1
    file3

To copy to clipboard, switch view to plain text mode 

//add file file4

<root>
- test
  file1
  file2
  - dir1
    file3
file4

<root>
- test
  file1
  file2
  - dir1
    file3
file4

To copy to clipboard, switch view to plain text mode 

//delete file1

<root>
- test
  file2
  - dir1
    file3
file4

<root>
- test
  file2
  - dir1
    file3
file4

To copy to clipboard, switch view to plain text mode 

//delete dir1

<root>
- test
  file2
file4

<root>
- test
  file2
file4

To copy to clipboard, switch view to plain text mode 

If i use QTreeView Widget i must rewrite ModelIndex to make it custom?
Or any other ideas how to do it?

Thank you!

Just create a normal model. When you want to add or remove items, emit the appropriate signals and all views will automatically update.

Well, can you give me more informations? The delete action isnt on the physical address, it's just on my program, so i dont really understand how to do that...

beginRemoveRows(...)
... remove rows from your data store ...
endRemoveRows()
