[...] Oh, and as for where to go to open this UI: well, it has to run in-process, but it's not common enough to warrant a toolbox entry, so I had a crazy idea: what if whatever kcm is relevant to this stuff (plasma settings + wherever the PDV setting lives?) had a button that sent a dbus signal to plasma-desktop to show the UI? i think should be reachable from the activity manager (either right click, another action icon, whatever) it's not related to activities, though. it's just made necessary by the way I did the activities. yes, but still i think is the logical place to reach it TODO: clean up the above rambling into a more structured document. :) [edit]Under the Hood [...] uhm, i think the authority shuld just be corona, but in case of plasma-desktop corona use the Activity to make the decision... well, right now the corona isn't the authority on anything. and for non- running activities, the containments' settings are the only authority. yes, i think the containments eing a source of authority for themselvescan be potentially problematic * Might it be easier to leave the config in plasma-desktop-appletsrc, and have the startup loading skip containments assigned to nonexistant screens/desktops? in the end, where you have the configuration is the same thing, depends if it's ever wanted having running containments not associated with screens. the exceptions are the mobile and netbook launchers, but they could have -1 (instead of a number than available screens) no, any containment that was never associated with a screen will be completely ignored by all of this code. :) also... at the moment, code that wants to work with desktop containments checks whether a containment is in offscreenwidgets in order to skip any dashboards. * Once this is implemented, I believe panels should behave the same way, instead of migrating. It's more consistent that way. thoughts? agree * It'd be nice to investigate whether any delay would be helpful - is it likely for several screen changes to happen within a few seconds? either from drivers being fidgety or from a loose cable or something? I don't know enough to be sure. yes, two things likely to happen do we have any evidence for this, though? do you *think* it's likely or *know* it's likely? :) at the moment just thinking it's likely Cheers, Marco Martin ___ Plasma-devel mailing list Plasma-devel@kde.org https://mail.kde.org/mailman/listinfo/plasma-devel

Per-desktop views have been turned off and there are now several unused widget layouts. Would you like them to be removed automatically for you? This can result in a significant performance improvements. Remove Unused Layouts Keep The Unused Layouts uhm, not sure, it's a too technical question, just deleting could piss people off tough so yeah :/ When a screen is disconnected (or in PDV, a desktop removed) the associated containment and view (for each running activity) should be automatically stopped - and resumed again when the screen/desktop returns. We can migrate panels, but not desktops, and it doesn't make sense to leave something running and inaccessible (having to manually stop it would also be Wrong). it does make sense to leave something running if one can switch to it, though. if the switcher UI allows the user to do that, then it's probably fine. except that I'm not sure how many users will realise they might have stuff running still and check this tool. they'll just think their system got slower because it's bloated or something :P me, I plug in an external monitor (actually a tv) a couple of times a week to watch movies. I don't want the containment for it running for the rest of the week, and I don't really want to manually delete or close it every time. and the multiscreen tool would then need a feature to manually close things instead of deleting them, too. how much weight (start up time, memory usage) does this use case incur right now? wallpapers on loaded on first-paint only, if there are no widgets then none are loaded or set up ... it might be very negligable and not work worrying about. however it won't be negligable on netbook and mobile, but i was thinking about explicity stopping and restarting activities here -- Marco Martin ___ Plasma-devel mailing list Plasma-devel@kde.org https://mail.kde.org/mailman/listinfo/plasma-devel

Umm, is there a glossary somewhere of plasma terms? I've no clue what PDV, or such mean. per virtual desktop activities, a different containment on each virtual desktop. it's a feature that turned out to be really troublesome to adapt in the current activities development, but unfortunately turned out to be loved quite a bit, so will have to stay :/ Cheers, Marco Martin ___ Plasma-devel mailing list Plasma-devel@kde.org https://mail.kde.org/mailman/listinfo/plasma-devel
mentors needed
Heya folks :) I need mentors for a GSoC-like program in Canada asap so please get back to me within the next two days. What's needed: - a mentor who can come to Toronto from October 1-3. - a chunk of work that's suitable for a group of 5-10 upper-year computer science students to work on for a semester. They have about 10 hours a week available between September and the beginning of December. Let me know if you're interested to mentor, have a project for them and can travel to Toronto on these days. Let's get some more students to write code for KDE :) You can find out more about the program at http://ucosp.ca/about/ Cheers Lydia -- Lydia Pintscher Amarok community manager kde.org - amarok.kde.org - kubuntu.org claimid.com/nightrose ___ Plasma-devel mailing list Plasma-devel@kde.org https://mail.kde.org/mailman/listinfo/plasma-devel
