48 \class QGLFunctions-
49 \inmodule QtOpenGL-
50 \brief The QGLFunctions class provides cross-platform access to the OpenGL ES 2.0 API.-
51 \since 4.8-
52 \obsolete-
53 \ingroup painting-3D-
54-
55 OpenGL ES 2.0 defines a subset of the OpenGL specification that is-
56 common across many desktop and embedded OpenGL implementations.-
57 However, it can be difficult to use the functions from that subset-
58 because they need to be resolved manually on desktop systems.-
59-
60 QGLFunctions provides a guaranteed API that is available on all-
61 OpenGL systems and takes care of function resolution on systems-
62 that need it. The recommended way to use QGLFunctions is by-
63 direct inheritance:-
64-
65 \code-
66 class MyGLWidget : public QGLWidget, protected QGLFunctions-
67 {-
68 Q_OBJECT-
69 public:-
70 MyGLWidget(QWidget *parent = 0) : QGLWidget(parent) {}-
71-
72 protected:-
73 void initializeGL();-
74 void paintGL();-
75 };-
76-
77 void MyGLWidget::initializeGL()-
78 {-
79 initializeGLFunctions();-
80 }-
81 \endcode-
82-
83 The \c{paintGL()} function can then use any of the OpenGL ES 2.0-
84 functions without explicit resolution, such as glActiveTexture()-
85 in the following example:-
86-
87 \code-
88 void MyGLWidget::paintGL()-
89 {-
90 glActiveTexture(GL_TEXTURE1);-
91 glBindTexture(GL_TEXTURE_2D, textureId);-
92 ...-
93 }-
94 \endcode-
95-
96 QGLFunctions can also be used directly for ad-hoc invocation-
97 of OpenGL ES 2.0 functions on all platforms:-
98-
99 \code-
100 QGLFunctions glFuncs(QGLContext::currentContext());-
101 glFuncs.glActiveTexture(GL_TEXTURE1);-
102 \endcode-
103-
104 QGLFunctions provides wrappers for all OpenGL ES 2.0 functions,-
105 except those like \c{glDrawArrays()}, \c{glViewport()}, and-
106 \c{glBindTexture()} that don't have portability issues.-
107-
108 Including the header for QGLFunctions will also define all of-
109 the OpenGL ES 2.0 macro constants that are not already defined by-
110 the system's OpenGL headers, such as \c{GL_TEXTURE1} above.-
111-
112 The hasOpenGLFeature() and openGLFeatures() functions can be used-
113 to determine if the OpenGL implementation has a major OpenGL ES 2.0-
114 feature. For example, the following checks if non power of two-
115 textures are available:-
116-
117 \code-
118 QGLFunctions funcs(QGLContext::currentContext());-
119 bool npot = funcs.hasOpenGLFeature(QGLFunctions::NPOTTextures);-
120 \endcode-
121-
122 \note This class has been deprecated in favor of QOpenGLFunctions.-
