Creating a Window

Handling Keyboard Input in SDL

How can I handle keyboard inputs in an SDL application?

This is the answer to the question. Handling keyboard input in SDL is straightforward using the SDL event system. You need to check for SDL_KEYDOWN and SDL_KEYUP events in your event loop. Here's a simple example that reacts to keyboard inputs:

#include <SDL.h>

int main(int argc, char** argv) {
  SDL_Window* window = SDL_CreateWindow(
    "Keyboard Input Window",
    640, 480, 0
  SDL_Event event;
  bool running = true;

  while (running) {
    while (SDL_PollEvent(&event)) {
      if (event.type == SDL_QUIT) {
        running = false;
      } else if (event.type == SDL_KEYDOWN) {
        switch (event.key.keysym.sym) {
          case SDLK_ESCAPE:
            running = false;
            // Handle other key presses here

  return 0;

This code initializes an SDL window and processes keyboard input to close the window when the Escape key is pressed.
