Well KWindowSystem is Qt only, but I don't know about Qt4. It already implements everything as xcb instead of xlib (xlib doesn't work, which afaik would be needed for Qt4). Wayland would be supported by switching to kwindowsystem as it has different backends (X11 backend, egl backend).
About Qt4 it would be possible even for Qt4 to use kwindowsystem indirectly. A reference on how to do that, would be https://github.com/damianatorrpm/qmltaskbar (please excuse me but my C is less than novice) . In my lib I depend on kwindowsystem and libqtxdg. It has an API like: qmltaskbar::windowList ==> all ID's of the windows (NETWM dock, desktop and SkipTaskbar etc should be filtered already) qmltaskbar::applicationList ==> all .desktop files from XDG_Datadirs and of course functions like minimize, maximize,close etc but some things are still missing. I really really recommend you kwindowsystem as you would a have a Qt only lib, supporting X and Wayland already, no duplicating of code. A reference on how good a panel works with kwindowsystem would be here https://github.com/damianatorrpm/qmlpanel 2014-04-11 2:23 GMT+02:00 PCMan <pcman...@gmail.com>: > On Fri, Apr 11, 2014 at 2:55 AM, Alexis López Zubieta > <azubi...@estudiantes.uci.cu> wrote: >> So I must start by replacing xfitman by KWindowSystem? >> About the panel plugins, are you planing to use the new Qt5 plugins >> capabilities for embedding meta-data or are we going to keep using the >> .desktop files? >> >> >> El 10/04/14 14:36, Damian Ivanov escribió: >>> Anything wrong with kwindowsystem.
