I have a pretty simple program. I'm just trying to acknowledge keyboard/mouse events, but I'm getting no log output (inside my SDL_PollEvent loop). I'm running just basic Raspian (no X).
#include <bcm_host.h>
#include <SDL.h>
#include <SDL_opengles2.h>
#include <iostream>
using namespace std;
int main(int argc, char** argv)
{
bcm_host_init();
SDL_Init(SDL_INIT_EVERYTHING);
SDL_DisplayMode mode;
SDL_GetDesktopDisplayMode(0, &mode);
cout << mode.w << 'x' << mode.h << endl;
auto window = SDL_CreateWindow(
"Test",
0,
0,
mode.w,
mode.h,
SDL_WINDOW_OPENGL);
if (!window)
{
cerr << "failed to make window: " << SDL_GetError() << '\n';
}
else
{
cout << "window created!\n";
SDL_SetWindowFullscreen(window, SDL_TRUE);
auto context = SDL_GL_CreateContext(window);
if (context)
{
cout << (const char*)glGetString(GL_VERSION) << endl;
glClearColor(0.0f, 0.5f, 0.5f, 1.0f);
SDL_Event event;
bool running = true;
int n = 0;
while (running && n < 10)
{
glClear(GL_COLOR_BUFFER_BIT);
SDL_GL_SwapWindow(window);
cout << "pulse " << ++n << endl;
while (SDL_PollEvent(&event))
{
cout << "EVENT" << endl;
if (event.type == SDL_MOUSEMOTION) cout << "mouse move" << endl;
if (event.type == SDL_MOUSEBUTTONDOWN ||
event.type == SDL_KEYDOWN) running = false;
}
SDL_Delay(500);
}
SDL_GL_DeleteContext(context);
}
else
{
cerr << "failed to make context: " << SDL_GetError() << '\n';
}
SDL_DestroyWindow(window);
}
SDL_Quit();
return 0;
}
I've tried messing with the flags passed to SDL_CreateWindow (such as SDL_WINDOW_INPUT_FOCUS and SDL_WINDOW_MOUSE_FOCUS) with no luck. The OpenGL works just fine, though: I get my colored screen (and even a visible mouse cursor in the upper left corner).
