Author Topic: sf::RenderWindow crash (Read 4464 times)

hippocat · « **on:** March 10, 2010, 03:52:53 pm »

I have ATI card, winXP, 2 monitors. So in my code:

        sf::WindowSettings st;
        st.AntialiasingLevel = 8;  // Make smooth drawing
        delete(m_pSfmlView);
        m_pSfmlView = new sf::RenderWindow(GetSafeHwnd(), st);

I have sporadic crash here:

Code: [Select]

void WindowImplWin32::CreateContext(const VideoMode& Mode, WindowSettings& Params)
{
...
	    bool  IsValid = wglChoosePixelFormatARB(myDeviceContext, IntAttributes, FloatAttributes, sizeof(Formats) / sizeof(*Formats), Formats, &NbFormats) != 0;

..
}

I can see that wglChoosePixelFormatARB is NULL.
looks like call

Code: [Select]

        // Get the wglChoosePixelFormatARB function (it is an extension)
        PFNWGLCHOOSEPIXELFORMATARBPROC wglChoosePixelFormatARB = reinterpret_cast<PFNWGLCHOOSEPIXELFORMATARBPROC>(wglGetProcAddress("wglChoosePixelFormatARB"));

failed. I have no idea why.

Hi

It's already fixed for SFML 1.6.

Could you give me patch at least ? Is it ok just to check for NULL?

You could download the SVN version.

Version 1.6 is "/trunk". Don't use "/tags/1.6", it was supposed to be the final version of 1.6 but I created it too early, and didn't update it since then.

Ok, thanks, it works now. Actually I have huge problem with small sprite that somehow gets stretched as background and have no idea why it appears.
