QT provides the graphic interface using wayland / eglfs to create for example menus. It provides also the communication with the camera and several other modules. The Qt can be replaced with gtk.But, the performance related to GTK using SDL is far away lower than QT.
So what is a better replacement with better performance for QT.
Thanks,
Hello,
Qt is the official in this case, if you change you don't have support for it in the official BSP I mean the GPU stuff is attached to qt so It's the best.
