SDL_GetMouseState

Retrieve the current state of the mouse.

Syntax

Uint32 SDL_GetMouseState(int *x, int *y);

Function Parameters

x

the x coordinate of the mouse cursor position relative to the focus window

y

the y coordinate of the mouse cursor position relative to the focus window

Return Value

Returns a 32-bit button bitmask of the current button state.

Remarks

The current button state is returned as a button bitmask, which can be tested using the SDL_BUTTON(X) macros (where X is generally 1 for the left, 2 for middle, 3 for the right button), and x and y are set to the mouse cursor position relative to the focus window. You can pass NULL for either x or y.

Code Examples

int x, y;
Uint32 buttons;

SDL_PumpEvents();  // make sure we have the latest mouse state.

buttons = SDL_GetMouseState(&x, &y);

SDL_Log("Mouse cursor is at %d, %d", x, y);
if ((buttons & SDL_BUTTON_LMASK) != 0) {
    SDL_Log("Mouse Button 1 (left) is pressed.");
}
