获取显示屏的个数和分辨率 — 通过使用OpenGL的GLFW库

程序

#include 
     
      // GLFW#include 
      
       int main(){    // Init GLFW    glfwInit();    // Set all the required options for GLFW    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);    glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);    int monitorCount;    //GLFWmonitor* pMonitor = glfwGetPrimaryMonitor();    GLFWmonitor** pMonitor =  glfwGetMonitors(&monitorCount);    std::cout << "Now, Screen number is " << monitorCount << std::endl;    for(int i=0; i
      
     

运行程序

Now, Screen number is 2Screen size is X = 1920, Y = 1080Screen size is X = 1280, Y = 1024
