sashikknox In some cases, need create EGLWindow with SDLWindow. In X11 i can get pointer to NativeWindow from **struct SDL_SysWMinfo wmInfo** ```C++ struct SDL_SysWMinfo wmInfo; SDL_GetWindowWMInfo(ptSDLWindow, &wmInfo) #if defined(__unix__) && defined(SDL_VIDEO_DRIVER_X11) nativeWindow=(EGLNativeWindowType)wmInfo.info.x11.window; nativeDisplay=(EGLNativeDisplayType)wmInfo.info.x11.display; #endif ``` than i can create EGLSurface ``` eglCreateWindowSurface(nativeDisplay, EGL_CONFIG, nativeWindow, SURFACE_ATTRIBUTES); ``` in Wayland i can do it with same way, just need pointer to **EGLWindow**, we already have pointer to **wl_display** from **SDL_sysWMInfo**, need add to **wl** struct in SDL_SysWMInfo another pointer to **struct wl_egl_window *egl_window;**. And in wayland backend, in function **Wayland_GetWindowWMInfo** return pointer to **egl_window** from **SDL_WindowData** Now i use patched statically built SDL2 in port of Quake 2 GLES2 for SailfishOS (it use QtWayland): link to SDL2 commit and changed string for patch: - |
