Review request for kdelibs, Peter Penz and Fredrik Höglund.


Summary
-------

I propose to provide the destination of a symbolic link as additional information in KFileItemDelegate. This will enable us to provide that as a column in Dolphin's and Konqueror's Details View, which has been requested a couple of times (note that KDE 3 had that feature).

Like Sebastian who filed the related request http://reviewboard.kde.org/r/3354/, I think that this information may be useful outside Dolphin and should therefore be provided in KFileItemDelegate. Additionally, Dolphin currently stores the additional columns which are enabled in a KFileItemDelegate::InformationList, which means that not adding this information in KFID, but only in Dolphin itself would require a total rewrite of the code that stores the additional columns.

Any feedback is appreciated. If nobody (in particular Fredrik) objects, I'd like to commit this on Monday to make sure that we can get this feature into 4.5. I could include Sebastian's patch in my commit if there is agreement that both additions to KFID are desirable.

Testing
-------

I've got a patch for Dolphin that makes use of this in the Details View - works as expected for me.


Thanks,
