Currently, our default on each platform is hardcoded. Windows - "windows" Linux - "xcb" Mac - "cocoa" The default can be changed by passing -qpa wayland to configure. IOW, the default is built into the qtgui binary. There is no runtime detection of default. The use case where the env variable doesn't work well is: User is running qt/xcb today. User installs qt/wayland plugin to test wayland support. I guess the distro package has to then modify /etc/environ or something? Is there a better way environment variables can be set (and better just for Qt apps). I don't really have a solution. (qt.conf seems an OK solution) Girish _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
