Event

[Broken]

Hi! I'm new here and I need help I start with tutorials
Now I working with event handling

Code: [Select]

#include<SFML/Window.hpp>
int main()
{
sf::Window App(sf::VideoMode(800, 600, 32), "SFML Window");
bool Running=true;
while(Running)
{
App.Display();
}
while (App.IsOpened())
{
    sf::Event Event;
    while (App.GetEvent(Event))
    {
        // Window closed
        if (Event.Type == sf::Event::Closed)
            App.Close();

        // Escape key pressed
        if ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
            App.Close();
    }
}
return EXIT_SUCCESS;
}



when I compile and build code I get window but when I press Esc or X it can't close window
sry on my english I hope that you understand me

That's definitely not in the tutorial.

You have two loops and you never get out of the first one.

Yes that is not from tutorial but that is code from tutorial can you correct what is wrong

[Dominator]

You have to put the event loop in the main loop. I'd do it like this:

Code: [Select]


  while (Running && App.IsOpened()) //main loop
  {
     App.Display();

     while (App.GetEvent(Event)) //event loop
     {
        //handle events
     }
  }


You should acquire some basic knowledge in programming first, loops are very fundamental.

thx

I have problem with time handling when i compile and run code i get this error

Code: [Select]

This is explained in the tutorial. There are even screenshots to show what to do in the project's settings.

[Broken]

in inputa I add sfml-window.lib in preprocesor SFML_DYNAMIC, I even add sfml-window.dll and sfml-system.dll in folder where is my project

[Laurent]

sf::Clock is defined in sfml-system.lib.

[Broken]

so in input i must put sfml-system.lib not sfml-window.lib why in tutorial about event handling is not included in source code <SFML/System.hpp>

[Laurent]

Because System.hpp is included by Window.hpp.

[Broken]

you say that in input always  must be sfml-system.lib ok i will try later because i have some work to do now

[Nexus]

you say that in input always  must be sfml-system.lib

Hmm, I don't know if I understand this right, but input handling is part of the Window package (the headers of which include the System package).

[Laurent]

I think he was talking about the "input libraries" field of the linker settings in Visual Studio

[Broken]

I try now and it doesn't work
I do this
file>new project>win32 console app.>source file>add new .cpp file>project>properties>c++>preprocessor>preprocessor definitions>where i write SFML_DYNAMIC; it looks like this "SFML_DYNAMIC;WIN32;_DEBUG;_CONSOLE">then linker>input>additional dependencies>sfml-system.lib>OK

I put sfml-system,-graphics dlls in folder where is project
and put this code in file .cpp

                    App.Close();

                // F1 key : capture a screenshot
                if (Event.Key.Code == sf::Key::F1)
                {
                    sf::Image Screen = App.Capture();
                    Screen.SaveToFile("screenshot.jpg");
                }
            }
        }

        // Clear the screen with red color
        App.Clear(sf::Color(200, 0, 0));

        // Display window contents on screen
        App.Display();
    }

    return EXIT_SUCCESS;
}

and build and then i get errors

 what is wrong?
