Ofcourse...

I somehow automatically thought NULL would be a no event value.

Thank you!

General / [solved]sf::Event::Closed is sent immediately after opening a new window ?

« on: January 10, 2016, 09:08:16 pm »

Hello all

I have done everything mentioned in the "read this before posting". I'm not able to find an explanation to this problem.

The problem is that if I open a new window, unless my mouse is on top of that window, it immediately gets sent a "sf::Event::Closed" event, even though it has just been created ! If however my mouse cursor happens to be on top of where the window opens, the event is not sent.

And, as I am polling for this event to close the window, the result is that the window gets closed immediately after it has been created - unless the mouse cursor is in the area of the window when it appears.

My environment is SFML 2.1 with MinGW.

Below is the code to reproduce the problem:

main.cpp

#include "problem.h"

int main()
{
    test_SFML();
    while (1)
    {
        pollEsc();
    }

}

problem.cpp

#include "problem.h"

using namespace sf;

sf::RenderWindow simWindow;
sf::View simScreen(sf::FloatRect(0, 0, 320, 240));
sf::Color col0(250, 250, 250); // background
sf::Event simEvent;

void test_SFML(void)
{
    simWindow.create(sf::VideoMode(320, 240), "test");
    simScreen.setViewport(sf::FloatRect(0, 0, 1, 1));
    simWindow.setView(simScreen);
    simWindow.clear(col0);
    simWindow.display();
}

int pollEsc() {
simWindow.pollEvent(simEvent);
    if(simEvent.type == sf::Event::Closed) {
       simWindow.close();
       return -1;
    }
return 0;
}
 

problem.h

#ifndef PROBLEM_H
#define PROBLEM_H

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

extern void test_SFML();
extern int pollEsc();

#endif // PROBLEM_H
