I’ve had good luck interfacing with KDE windows using dbus in python, although if I remember right the more granular control also required javascript (still passed thru dbus with python). The only python library I needed was Qt (for their dbus implementation because I was already using their event loop, but any other lightweight dbus package should work fine).
I remember being able to figure out a solution with the kwin docs and dfeet for introspection, but it was a while ago and my memory is less than stellar lol. I ended up running all my window-related logic in the kwin script (js) and just using python+dbus to see if the script had been injected and do it if not. If you go the same route (though the python is unnecessary this way if you aren’t using it for something else, like running one of the windows you wanna manipulate) the
workspace
global variable stores all windows instackingOrder
, so looping through that list (for (window of workspace.stackingOrder) {…}
) is an easy way to check each window. I definitely remember docs on the workspace/windows part, but tbh I think I just introspected with the jsconsole.log
and the log kwin prints it to (journalctl maybe?). Sorry I don’t remember more about the process, I got into the kwin scripting for all of an hour cuz of the Wayland regression of not being able to control your own window’s size/position in qt so it was a bit of a hack fix I haven’t had to think about since.
