The recommended way to use QGLFunctions is by + direct inheritance: + + \code + class MyGLWidget : public QGLWidget, protected QGLFunctions + { + Q_OBJECT + public: + MyGLWidget(QWidget *parent = 0) : QGLWidget(parent) {} + + protected: + void initializeGL(); + void paintGL(); + }; + + void MyGLWidget::initializeGL() + { + initializeGLFunctions(); + } + \endcode + + The \c{paintGL()} function can then use any of the OpenGL/ES 2.0 + functions without explicit resolution, such as glActiveTexture() + in the following example: + + \code + void MyGLWidget::paintGL() + { + glActiveTexture(GL_TEXTURE1); + glBindTexture(GL_TEXTURE_2D, textureId); + ... + } + \endcode + + QGLFunctions can also be used directly for ad-hoc invocation + of OpenGL/ES 2.0 functions on all platforms: + + \code + QGLFunctions glFuncs(QGLContext::currentContext()); + glFuncs.glActiveTexture(GL_TEXTURE1); + \endcode + + QGLFunctions provides wrappers for all OpenGL/ES 2.0 functions, + except those like \c{glDrawArrays()}, \c{glViewport()}, and + \c{glBindTexture()} that don't have portability issues. + + Including the header for QGLFunctions will also define all of + the OpenGL/ES 2.0 macro constants that are not already defined by + the system's OpenGL headers, such as \c{GL_TEXTURE1} above. + + The hasOpenGLFeature() and openGLFeatures() functions can be used + to determine if the OpenGL implementation has a major OpenGL/ES 2.0 + feature. For example, the following checks if non power of two + textures are available: + + \code + QGLFunctions funcs(QGLContext::currentContext()); + bool npot = funcs.hasOpenGLFeature(QGLFunctions::NPOTTextures); + \endcode +*/ + +/*! + \enum QGLFunctions::OpenGLFeature + This enum defines OpenGL/ES 2.0 features that may be optional + on other platforms. + + \value Multitexture glActiveTexture() function is available. + \value Shaders Shader functions are available. + \value Buffers Vertex and index buffer functions are available. + \value Framebuffers Framebuffer object functions are available. + \value BlendColor glBlendColor() is available. + \value BlendEquation glBlendEquation() is available. + \value BlendEquationSeparate glBlendEquationSeparate() is available. + \value BlendFuncSeparate glBlendFuncSeparate() is available. + \value BlendSubtract Blend subtract mode is available. + \value CompressedTextures Compressed texture functions are available. + \value Multisample glSampleCoverage() function is available. + \value StencilSeparate Separate stencil functions are available. + \value NPOTTextures Non power of two textures are available. +*/ + +// Hidden private fields for additional extension data. +struct QGLFunctionsPrivateEx : public QGLFunctionsPrivate +{ + QGLFunctionsPrivateEx(const QGLContext *context = 0) + : QGLFunctionsPrivate(context) + , m_features(-1) {} + + int m_features; +}; + +#if QT_VERSION >= 0x040800 +Q_GLOBAL_STATIC(QGLContextGroupResource<QGLFunctionsPrivateEx>, qt_gl_functions_resource) +#else +static void qt_gl_functions_free(void *data) +{ + delete reinterpret_cast<QGLFunctionsPrivateEx *>(data); +} + +Q_GLOBAL_STATIC_WITH_ARGS(QGLContextResource, qt_gl_functions_resource, (qt_gl_functions_free)) +#endif +static QGLFunctionsPrivateEx *qt_gl_functions(const QGLContext *context = 0) +{ + if (!context) + context = QGLContext::currentContext(); + Q_ASSERT(context); + QGLFunctionsPrivateEx *funcs = + reinterpret_cast<QGLFunctionsPrivateEx *> + (qt_gl_functions_resource()->value(context)); +#if QT_VERSION < 0x040800 + if (!funcs) { + funcs = new QGLFunctionsPrivateEx(); + qt_gl_functions_resource()->insert(context, funcs); + } +#endif + return funcs; +} + +/*! + Constructs a default function resolver.
