General discussions / How to use drawing in main thread and read from the keyboard in another thread

« on: December 13, 2013, 06:27:04 pm »

Hi All,

I am trying to draw in main thread and read from the keyboard in another thread without success. I can draw but can not read number 5. Does anyone have any suggestions? Below my code:

#include <SFML/Graphics.hpp>
#include <SFML/System.hpp>

using namespace std;

bool trigger = false;

void eventThread(sf::RenderWindow* window)
{
   sf::Event event;

while(trigger)
   {
      while (window->pollEvent(event))
               {
                // check the type of the event...
                       switch (event.type)
                       {
                         // key pressed
                         case sf::Event::KeyPressed:
                  if(event.key.code == sf::Keyboard::Num5) {
                           cout << "5" << endl;
                                          }
                  break;
                       } // end of switch
               } // end of Poll Event
   } // end of while of trigger
} // end of function


int main(int argc, char *argv[])
{

    // create the window
    sf::RenderWindow window(sf::VideoMode(1600, 900), "REG", sf::Style::Fullscreen);

    window.setActive(false);
    trigger = true;
    sf::Thread thread(&eventThread, &window);
    thread.launch();

    bool quit = false;
    while (!quit) {
            draw my staff with success
    }

   trigger = false;
   thread.wait();

   return 0;

}

Thank you,

Uril.
