SDL_MouseButtonEvent - Mouse button event structure

  typedef struct{
    Uint8 type;
    Uint8 button;
    Uint8 state;
    Uint16 x, y;
  } SDL_MouseButtonEvent;

type

SDL_MOUSEBUTTONDOWN or SDL_MOUSEBUTTONUP

button

The mouse button index (SDL_BUTTON_LEFT, SDL_BUTTON_MIDDLE, SDL_BUTTON_RIGHT)

state

SDL_PRESSED or SDL_RELEASED

x, y

The X/Y coordinates of the mouse at press/release time

SDL_MouseButtonEvent is a member of the SDL_Event union and is used when an event of type SDL_MOUSEBUTTONDOWN or SDL_MOUSEBUTTONUP is reported.

When a mouse button press or release is detected then number of the button pressed (from 1 to 255, with 1 usually being the left button and 2 the right) is placed into button, the position of the mouse when this event occured is stored in the x and the y fields. Like SDL_KeyboardEvent, information on whether the event was a press or a release event is stored in both the type and state fields, but this should be obvious.
