Gdkx11 on Wayland

Platform
1

One or more roxterm users would like the WINDOWID environment variable back. This requires the use of gdk_x11_window_get_xid(). I’ve made sure roxterm only calls it after compile-time and run-time checks:

#ifdef GDK_WINDOWING_X11
     if (GDK_IS_X11_DISPLAY(gdk_display_get_default()))
    {
        ...
    }
#endif

but I’m still concerned that when it’s running in Wayland but X11 was also available at compile-time, the presence of gdk_x11_window_get_xid() may cause GDK’s X11 backend shared library to be uselessly loaded. Is that the case, or does the Wayland backend include dummy versions of the gdk_x11 functions?

Hi!
As far as I know the gdk backends are not in separate libraries, there is only libgdk-3.so and all backends are included there. So you are not loading anything more or less in memory by doing that.

I see, the separate library for X11 was for GDK2. So there’s no compelling reason to provide a compile-time option to stop this being compiled in. Thanks.
