Confirmation for deletion of files in Dolphin settings also affects Gwenview

[Frank Reininghaus]

Hi everyone,

Burkhard recently made me aware of the following forum discussion:

http://forum.kde.org/viewtopic.php?f=213&t=110440

Some users have noticed that Gwenview does not ask for confirmation
when deleting a file if that confirmation is disabled in Dolphin. When
having a closer look at the issue, this is not really surprising
because Dolphin writes that setting to the global config kiorc, and
both applications use KIO to delete files, which respects that
setting.

However, this is not really a user-friendly solution and might even
lead to data loss if a user who does not find any way to
enable/disable confirmations in Gwenview assumes that it will always
ask before really deleting the file. Moreover, it appears that earlier
versions of Gwenview did offer to enable such a confirmation.

I think that we might want to

(a) Add a warning in Dolphin's settings dialog that the "Trash" and
"Delete" confirmations, unlike the "Close window with multiple tabs"
one, affects *all* KDE applications. One possibility would be to add
the text "Please note that this setting affects all KDE applications"
to the text next to the two checkboxes. Input from Burkhard would be
appreciated here because he works a lot with texts in the GUI and the
docs and might have better ideas how this could be solved.

(b) Restore the possibility to configure the confirmations in
Gwenview's settings dialog.

Comments and ideas are welcome.

Regards,
Frank
