crazy idea: what about qml-ifing the taskbar right now? since is the most complex applet will still be a c++ one (that would just show a DeclarativeWidget and nothing else) i have no idea how much work would take, the only hard thing seems to be a correct handling of grouping (i guess it will have to be written a qabstractitemmodel that maps to what libtaskmanager says) for the positioning and animate flowing there is *exactly* what we need the Flow positioner item, containing a Repeater hooked up to the model for the tasks, so there *could* be even less work in doing that rather than writing a qgrphicslayout subclass, that is the most hairy thing ever ;) (on a related note, i almost have a working systray in pure qml, since the mobile one thankfully doesn't support the xembed icons, it may be usable soon there) Cheers, Marco Martin _______________________________________________ Plasma-devel mailing list Plasma-devel@kde.org https://mail.kde.org/mailman/listinfo/plasma-devel
