"Is it not always org.kde.breeze.desktop?" No, because of third party developers. Not every project targets the desktop. That said, this applies to any use of Plasma::Package, which is meant to be a generic concept not something just for the limited set of package types plasmashell uses. It is helpful to think of it as a concept on its own rather than in the context of Plasma Desktop. Other Frameworks using applications really ought to be able to use Plasma::Package for their "bundles of data" needs. "It would usually be the packagestructure setting it, in initPackage()" In the case of Shell and Look & Feel packages I would caution against doing this, as it biases them to Plasma Desktop. The tablet interface in Plasma Active will need its own "root" L&F; falling back to components from breeze.desktop will likely be both an oversight and create undesirable results. It also would mean that every time someone touches a component in breeze.desktop that is used by the tablet UX, they will be required to ensure it remains appropriate on touch. For devices even further afield from desktop than tablets this becomes even more of an issue, and those devices may not want to ship breeze.desktop at all. Of course, there is the alternative which is to just tell system integrators to call their root package "org.kde.breeze.desktop" but I'm not sure that would be desirable. While setting this in initPackage is a reasonable stop-gap for now, this really ought to be something that gets defined in e.g. the shell package and set in plasmashell so that it can be tied to the shell. If no fallback is defined in the shell package, fair enough -> no fallback :) - Aaron J. ----------------------------------------------------------- This is an automatically generated e-mail.
