hi all... i experimented a bit this morning with cutting the fat from kactivitymanagerd. in particular i focussed on the following.
KUniqueApplication: this lives in kdeui ... just to provide a way to have only one instance of the app. ugh. in Frameworks there is libkdbus which has a KDBusService which provides the same capabilities. porting to that proved quite simple and straightforward and let ActivityManager become a QCoreApplication subclass. KWindowSystem: this one is more difficult. it is used only to track the comings and goings of windows. no other features are used. and it ends up causing a QWidget to be created, which KWindowSystem uses to filter x11 events. i don't have a great solution for this one .. but it would be very nice to have something that doesn't pull in such a heavy set of dependencies just to watch window states. i don't know if this would be general-purpose enough to end up in Frameworks (my gut says "no") but writing a simple class that can have a window-system-specific implementation that alerts when the window focus changes and windows are closed would make a lot of sense for kactivitymanagerd. so, i have a patch for the former, but nothing for the latter. any takers? :) -- Aaron J.
