SDL_MouseMotionEvent(3) SDL API Reference SDL_MouseMotionEvent(3)NAME
SDL_MouseMotionEvent - Mouse motion event structure
Uint16 x, y;
Sint16 xrel, yrel;
state The current button state
x, y The X/Y coordinates of the mouse
xrel, yrel Relative motion in the X/Y direction
SDL_MouseMotionEvent is a member of the SDL_Event union and is used when an event of type SDL_MOUSEMOTION is reported.
Simply put, a SDL_MOUSEMOTION type event occurs when a user moves the mouse within the application window or when SDL_WarpMouse is called.
Both the absolute (x and y) and relative (xrel and yrel) coordinates are reported along with the current button states (state). The button
state can be interpreted using the SDL_BUTTON macro (see SDL_GetMouseState).
If the cursor is hidden (SDL_ShowCursor(0)) and the input is grabbed (SDL_WM_GrabInput(SDL_GRAB_ON)), then the mouse will give relative
motion events even when the cursor reaches the edge fo the screen. This is currently only implemented on Windows and Linux/Unix-a-likes.
