WxWidgets and modern opengl (3.3+)

Question

有人知道WXWIDGETS库是否使用现代着色器样式OpenGl（3.3 ）效果很好？我发现的所有东西似乎都在使用旧样式。我希望将QT或WXWIDGETS用于我的应用程序，但是似乎让着色器的东西与小部件一起使用可能是一场噩梦。有人有这个经验吗？

在wxwidgets> = 3.1使用wxGLContext使用适当的Core-Context wxGLContextAttrs应该工作：

wxGLContextAttrs cxtAttrs;
cxtAttrs.CoreProfile().OGLVersion(3, 3).EndList();

正如RIPI2从金字塔样品中指出的那样：

//We create a wxGLContext in this constructor.
//We do OGL initialization at OnSize().
MyGLCanvas::MyGLCanvas(MyFrame* parent, const wxGLAttributes& canvasAttrs)
                       : wxGLCanvas(parent, canvasAttrs)
{
    m_parent = parent;
    m_oglManager = NULL;
    m_winHeight = 0; // We have not been sized yet
    // Explicitly create a new rendering context instance for this canvas.
    wxGLContextAttrs ctxAttrs;
#ifndef __WXMAC__
    // An impossible context, just to test IsOk()
    ctxAttrs.PlatformDefaults().OGLVersion(99, 2).EndList();
    m_oglContext = new wxGLContext(this, NULL, &ctxAttrs);
    if ( !m_oglContext->IsOK() )
    {
#if wxUSE_LOGWINDOW
        wxLogMessage("Trying to set OpenGL 99.2 failed, as expected.");
#endif // wxUSE_LOGWINDOW
        delete m_oglContext;
        ctxAttrs.Reset();
#endif //__WXMAC__
        ctxAttrs.PlatformDefaults().CoreProfile().OGLVersion(3, 2).EndList();
        m_oglContext = new wxGLContext(this, NULL, &ctxAttrs);
#ifndef __WXMAC__
    }
#endif //__WXMAC__
    if ( !m_oglContext->IsOK() )
    {
        wxMessageBox("This sample needs an OpenGL 3.2 capable driver.nThe app will end now.",
                     "OpenGL version error", wxOK | wxICON_INFORMATION, this);
        delete m_oglContext;
        m_oglContext = NULL;
    }
    else
    {
#if wxUSE_LOGWINDOW
        wxLogMessage("OpenGL Core Profile 3.2 successfully set.");
#endif // wxUSE_LOGWINDOW
    }
}
