详细描述

The QGLFunctions class provides cross-platform access to the OpenGL /ES 2.0 API.

OpenGL /ES 2.0 defines a subset of the OpenGL specification that is common across many desktop and embedded OpenGL implementations. However, it can be difficult to use the functions from that subset because they need to be resolved manually on desktop systems.

QGLFunctions provides a guaranteed API that is available on all OpenGL systems and takes care of function resolution on systems that need it. The recommended way to use QGLFunctions is by direct inheritance:

class MyGLWidget : public QGLWidget, protected QGLFunctions
{
    Q_OBJECT
public:
    MyGLWidget(QWidget *parent = 0) : QGLWidget(parent) {}
protected:
    void initializeGL();
    void paintGL();
};
void MyGLWidget::initializeGL()
{
    initializeGLFunctions();
}

The paintGL() function can then use any of the OpenGL /ES 2.0 functions without explicit resolution, such as glActiveTexture () in the following example:

void MyGLWidget::paintGL()
{
    glActiveTexture(GL_TEXTURE1);
    glBindTexture(GL_TEXTURE_2D, textureId);
    ...
}

QGLFunctions can also be used directly for ad-hoc invocation of OpenGL /ES 2.0 functions on all platforms:

QGLFunctions glFuncs(QGLContext::currentContext());
glFuncs.glActiveTexture(GL_TEXTURE1);

QGLFunctions provides wrappers for all OpenGL /ES 2.0 functions, except those like glDrawArrays() , glViewport() ，和 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 GL_TEXTURE1 above.

The hasOpenGLFeature () 和 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:

QGLFunctions funcs(QGLContext::currentContext());
bool npot = funcs.hasOpenGLFeature(QGLFunctions::NPOTTextures);

bool QGLFunctions:: hasOpenGLFeature ( QGLFunctions::OpenGLFeature feature ) const

返回 true 若 feature is present on this system's OpenGL implementation; false otherwise.

It is assumed that the QGLContext associated with this function resolver is current.

另请参阅 openGLFeatures ().

void QGLFunctions:: initializeGLFunctions (const QGLContext * context = 0)

Initializes GL function resolution for context 。若 context is null, then the current QGLContext 会被使用。

After calling this function, the QGLFunctions object can only be used with context and other contexts that share with it. Call initializeGLFunctions() again to change the object's context association.

QGLFunctions::OpenGLFeatures QGLFunctions:: openGLFeatures () const

Returns the set of features that are present on this system's OpenGL 实现。

It is assumed that the QGLContext associated with this function resolver is current.
