You need to recompile SFML with your version of glew.

No...

Interesting, because without recompiling I have the same errors.

I was reminded of this problem.

I'll explain it as simply as I can.

Expected result

Code: [Select]

click outside the window LostFocus
click inside the window GainedFocus
But result is

Code: [Select]

click outside the window LostFocus and GainedFocus
click inside the window ??? nothing

Audio / Re: getPlayingOffset returns 0 when it shouldn't

Switching these two lines is not the solution (it may work but it's not clean)

This way is a bit hacky but it can save memory.

You should load new data in a sf::SoundBuffer different from m_sound's current buffer.

Without any information about this limitation it is also not clear.

maly whate are you trying to communicate with your code?

my code refers to the example and says "move up this line".

btw, latest source does not fix that problem.

ps. i hate english grammar.

        sf::Time time = m_sound.getPlayingOffset();
        m_currBuffer.loadFromSamples(origSamples, sampleCount, m_origBuffer.getChannelCount(), m_origBuffer.getSampleRate());
        //sf::Time time = m_sound.getPlayingOffset();

Window / Re: Change viewport to keep aspect ratio of scene

« on: August 01, 2014, 08:42:49 am »

when you resize the window always set a new view.

basicSettings.screenx and basicSettings.screeny doing strange offsets.

sf::View v( sf::FloatRect( sf::Vector2f( basicSettings.screenx, basicSettings.screeny ), \
                               sf::Vector2f( basicSettings.screenw, basicSettings.screenh ) ) );

try

sf::View v( sf::FloatRect( sf::Vector2f( 0, 0 ), \
                               sf::Vector2f( basicSettings.screenw, basicSettings.screenh ) ) );

example

#include <SFML/Graphics.hpp>

sf::View calcView(const sf::Vector2u &windowsize, const sf::Vector2u &designedsize)
{
    sf::FloatRect viewport(0.f, 0.f, 1.f, 1.f);

    float screenwidth = windowsize.x / static_cast<float>(designedsize.x);
    float screenheight = windowsize.y / static_cast<float>(designedsize.y);

    if(screenwidth > screenheight)
    {
        viewport.width = screenheight / screenwidth;
        viewport.left = (1.f - viewport.width) / 2.f;
    }
    else if(screenwidth < screenheight)
    {
        viewport.height = screenwidth / screenheight;
        viewport.top = (1.f - viewport.height) / 2.f;
    }

    sf::View view( sf::FloatRect( 0, 0, designedsize.x , designedsize.y ) );
    view.setViewport(viewport);

    return view;
}

int main()
{
    const sf::Vector2u designedsize(320,200);

    sf::RenderWindow app(sf::VideoMode(800, 400), "SFML window");
    app.setView(calcView(app.getSize(), designedsize));

    while (app.isOpen())
    {
        sf::Event event;
        while (app.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                app.close();
            if (event.type == sf::Event::Resized)
                app.setView(calcView(sf::Vector2u(event.size.width, event.size.height), designedsize));
        }

        app.clear();
        sf::CircleShape circle(5);
        for(int y = 0; y < designedsize.y/10; ++y)
        {
            for(int x = 0; x < designedsize.x/10; ++x)
            {
                circle.setPosition(x * 10, y * 10);
                circle.setFillColor( (x + y) & 1 ? sf::Color::Blue:sf::Color::Green);
                app.draw(circle);
            }
        }
        app.display();
    }
    return 0;
}

Something like this?

float screenwidth = windowsize.x / static_cast<float>(gamesize.x);
float screenheight = windowsize.y / static_cast<float>(gamesize.y);

sf::FloatRect viewport;
viewport.width = 1.f;
viewport.height = 1.f;

if(screenwidth > screenheight)
{
        viewport.width = screenheight / screenwidth;
        viewport.left = (1.f - viewport.width) / 2.f;
}
else if(screenwidth < screenheight)
{
        viewport.height = screenwidth / screenheight;
        viewport.top = (1.f - viewport.height) / 2.f;
}

sf::View v( sf::FloatRect( 0, 0, gamesize.x , gamesize.y ) );
v.setViewport(viewport);

Window / Re: Unexpected GainedFocus event

« on: June 27, 2014, 12:49:14 pm »

It just trigger GainedFocus event when losing focus.
 
My solution is add flag SWP_NOACTIVATE but I have no idea, if it's good idea.

void WindowImplWin32::setPosition(const Vector2i& position)
{
        SetWindowPos(m_handle, NULL, position.x, position.y, 0, 0, SWP_NOSIZE | SWP_NOZORDER | SWP_NOACTIVATE);
}

void WindowImplWin32::setSize(const Vector2u& size)
{
    // SetWindowPos wants the total size of the window (including title bar and borders),
    // so we have to compute it
    RECT rectangle = {0, 0, static_cast<long>(size.x), static_cast<long>(size.y)};
    AdjustWindowRect(&rectangle, GetWindowLong(m_handle, GWL_STYLE), false);
    int width  = rectangle.right - rectangle.left;
    int height = rectangle.bottom - rectangle.top;

    SetWindowPos(m_handle, NULL, 0, 0, width, height, SWP_NOMOVE | SWP_NOZORDER | SWP_NOACTIVATE);
}

Window / Unexpected GainedFocus event

« on: June 27, 2014, 10:59:53 am »

When I click on other window(LostFocus) setSize and setPosition gives me GainedFocus.
SFML 2.1 on Windows XP.

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

int main()
{
    sf::Window app(sf::VideoMode(100, 100), "SFML window");
    //sf::RenderWindow app(sf::VideoMode(100, 100), "SFML window");

    while (app.isOpen())
    {
        //app.setPosition(app.getPosition());
        app.setSize(app.getSize());

        sf::Event event;
        while (app.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                app.close();
            else if(event.type == sf::Event::LostFocus)
                std::cout << "LostFocus" << std::endl;
            else if(event.type == sf::Event::GainedFocus)
                std::cout << "GainedFocus" << std::endl;
        }
    }
    return 0;
