SDL_MouseWheelEvent does not provide the mouse location, so we used SDL_GetMouseState() to retrieve it. Unfortunately, SDL_GetMouseState() returns a position expressed in the window coordinate system while the position filled in SDL events are expressed in the renderer coordinate system. As a consequence, the scroll was not applied at the right position on the device. Therefore, convert the coordinate system. See <https://stackoverflow.com/questions/49111054/how-to-get-mouse-position-on-mouse-wheel-event>. |
