Hi again, I forgot to mention that we may have to think about finding a way to truncate the long or large text values. Not as easy as it sounds though.
I have added a message to prevent empty attribute names: in the list, if you deletes the name of an attribute and try to validate this change, a message dialog is shown and the attribute's name is unchanged. Can someone check this message and possibly correct it? Thanks. Also note that the value entry in the lower half of the dialog is still a GtkEntry (i.e. no multi-line text possible from this widget): as already said by Ales, it is very convenient to be able to leave this area with a simple 'Enter' (contrary to the previous dialog where multi-line text were possible from here). Regards, Patrick
