Hi framework-developers and packagers, with two frameworks I'm currently in the need to have something like QPA. I want to make it possible to provide windowing-system specific plugins for frameworks using a private API. The need arises first of all in kwindowsystem to support wayland [1]. To implement it we need a dependency to KWayland, which is currently part of kde-workspace and not yet up to the quality and stability levels needed to make it a framework. The second framework where I need such functionality is kglobalaccel where kwin needs to take over a large part of the functionality of the runtime to make it work on wayland at all.
I see the following possibilities to solve the problem: 1.Make it a private API without any ABI guarantee 2. Make it a public stable API with ABI guarantee 3. Make it a private API with so-version changes whenever the ABI changes Option 1 is closest to what Qt's QPA does, but I think this would be a nightmare for packagers. Option 2 could result in a nightmare for developers especially in the plugin infrastructure itself. With releases every month that could quickly end in classes like KWindowSystemPrivate32 and result in an unmanageable runtime check system. Personally I think Option 3 is the cleanest solution. Would this be acceptable for everyone? If yes are there any suggestions for where to install headers to, for naming the libraries, etc? Looking forward for your input, Cheers Martin [1] And obviously also other windowing systems if distributions/OSes want to add support for it.
