Deleting multiple linked files should show a single confirmation dialog

[HoussemNasri]

Follow up to #8659

When multiple linked items are removed, JabRef will show the "Delete the selected file permanently from disk" dialogue for each item separately. E.g., if the user removes 3 linked items, the dialogue asking whether the respective file should be deleted from disk or should just be removed from entry will be shown 3 times.

This is not the expected behaviour - instead the user would expect to answer this dialogue once for all items that were selected. So if the user selects the option "Remove from entry" from the dialogue, then this should be applied to all linked entries that have been selected for removal (not for each entry separately).

To view the linked files of an entry, follow these steps:

1. Open JabRef and open the entry editor for an item to which multiple files are linked (e.g., article + several supplements)
2. Navigate to the "General" tab and then go to the row "File"

The deleteFile() method in LinkedFilesEditorViewModel calls delete() method in LinkedFileViewModel.
In the delete() method a new dialog opens every time when delete() method is called to delete a file.


should I move the code of delete() method to deleteFile() method and only use delete() method to delete the file from disk.

This way the the dialog will be called only once.

I don't think moving delete to deleteFile will fix the issue. The problem here is that whenever a delete event is detected (e.g. User hits the delete keystroke) we are calling deleteFile for each selected file thus multiple dialogs show up. What you want to do is to call deleteFile only once when a delete event occurs.

Also, you don't want to display the same dialog when user tries to delete one file vs multiple files.

Here is an example of what IntelliJ does when user tries to delete a file(s):

One File

Multiple Files

Code Hint
Lookup this class and see what happens when a user hits the delete keystroke

Hi @HoussemNasri ,
I can work on this issue if there are no updates.I think the dialog box gui needs to be moved from LinkedFilesEditorViewModel to LinkedFilesEditor. Also do we want to list file names in case of deletion of multilple files ?
