There's no code in Qt yet, at this point it would be kdelibs/kded/kmimeassociations.cpp in git://anongit.kde.org/kdelibs > It's a bit unclear to me how the old stacks will react to something > like: > image/png=myapp.desktop[Edit]; > Will they just fail gracefully? Yep, the KDE implementation will just output a warning saying KMimeAssociations::parseAddedAssociations: ".../mimeapps.list" specifies unknown service "myapp.desktop[Edit]" in "Added Associations". But that's for mimeapps.list. I'm not sure what the suggested change for application .desktop files actually is. Ah, we're not talking about changing the way apps are associated with mimetypes, only about "desktop actions", i.e. typically contextual menu stuff? I wonder how the GUI is supposed to look like, to distinguish Open from Edit? I'm confused over all, because mimeapps.list is about application desktop files, not just about desktop files that define desktop actions. So, what should happen when writing image/png=myapp.desktop[Edit]; and myapp.desktop simply says Exec=gimp ?
