<!-- $$$QOpenGLFunctions-description -->
<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qopenglfunctions.html">QOpenGLFunctions</a> class provides cross-platform access to the OpenGL ES 2.0 API.</p>
<p>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.</p>
<p><a href="qopenglfunctions.html">QOpenGLFunctions</a> 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 <a href="qopenglfunctions.html">QOpenGLFunctions</a> is by direct inheritance:</p>
<pre class="cpp">
<span class="keyword">class</span> MyGLWindow : <span class="keyword">public</span> <span class="type"><a href="qwindow.html">QWindow</a></span><span class="operator">,</span> <span class="keyword">protected</span> <span class="type"><a href="qopenglfunctions.html#QOpenGLFunctions">QOpenGLFunctions</a></span>
{
Q_OBJECT
<span class="keyword">public</span>:
MyGLWindow(<span class="type"><a href="qscreen.html">QScreen</a></span> <span class="operator">*</span>screen <span class="operator">=</span> <span class="number">0</span>);
<span class="keyword">protected</span>:
<span class="type">void</span> initializeGL();
<span class="type">void</span> paintGL();
<span class="type"><a href="qopenglcontext.html">QOpenGLContext</a></span> <span class="operator">*</span>m_context;
};
MyGLWindow(<span class="type"><a href="qscreen.html">QScreen</a></span> <span class="operator">*</span>screen)
: <span class="type"><a href="qwindow.html">QWindow</a></span>(screen)<span class="operator">,</span> <span class="type"><a href="../qtwidgets/qopenglwidget.html">QOpenGLWidget</a></span>(parent)
{
setSurfaceType(OpenGLSurface);
create();
<span class="comment">// Create an OpenGL context</span>
m_context <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qopenglcontext.html">QOpenGLContext</a></span>;
m_context<span class="operator">-</span><span class="operator">></span>create();
<span class="comment">// Setup scene and render it</span>
initializeGL();
paintGL();
}
<span class="type">void</span> MyGLWindow<span class="operator">::</span>initializeGL()
{
m_context<span class="operator">-</span><span class="operator">></span>makeCurrent(<span class="keyword">this</span>);
initializeOpenGLFunctions();
}
</pre>
<p>The <code>paintGL()</code> function can then use any of the OpenGL ES 2.0 functions without explicit resolution, such as <a href="qopenglfunctions.html#glActiveTexture">glActiveTexture</a>() in the following example:</p>
<pre class="cpp">
<span class="type">void</span> MyGLWindow<span class="operator">::</span>paintGL()
{
m_context<span class="operator">-</span><span class="operator">></span>makeCurrent(<span class="keyword">this</span>);
glActiveTexture(GL_TEXTURE1);
glBindTexture(GL_TEXTURE_2D<span class="operator">,</span> textureId);
<span class="operator">.</span><span class="operator">.</span><span class="operator">.</span>
m_context<span class="operator">-</span><span class="operator">></span>swapBuffers(<span class="keyword">this</span>);
m_context<span class="operator">-</span><span class="operator">></span>doneCurrent();
}
</pre>
<p><a href="qopenglfunctions.html">QOpenGLFunctions</a> can also be used directly for ad-hoc invocation of OpenGL ES 2.0 functions on all platforms:</p>
<pre class="cpp">
<span class="type"><a href="qopenglfunctions.html#QOpenGLFunctions">QOpenGLFunctions</a></span> glFuncs(<span class="type"><a href="qopenglcontext.html">QOpenGLContext</a></span><span class="operator">::</span>currentContext());
glFuncs<span class="operator">.</span>glActiveTexture(GL_TEXTURE1);
</pre>
<p>An alternative approach is to query the context's associated <a href="qopenglfunctions.html">QOpenGLFunctions</a> instance. This is somewhat faster than the previous approach due to avoiding the creation of a new instance, but the difference is fairly small since the internal data structures are shared, and function resolving happens only once for a given context, regardless of the number of <a href="qopenglfunctions.html">QOpenGLFunctions</a> instances initialized for it.</p>
<pre class="cpp">
<span class="type"><a href="qopenglfunctions.html#QOpenGLFunctions">QOpenGLFunctions</a></span> <span class="operator">*</span>glFuncs <span class="operator">=</span> <span class="type"><a href="qopenglcontext.html">QOpenGLContext</a></span><span class="operator">::</span>currentContext()<span class="operator">-</span><span class="operator">></span>functions();
glFuncs<span class="operator">-</span><span class="operator">></span>glActiveTexture(GL_TEXTURE1);
</pre>
<p><a href="qopenglfunctions.html">QOpenGLFunctions</a> provides wrappers for all OpenGL ES 2.0 functions, including the common subset of OpenGL 1.x and ES 2.0. While such functions, for example <a href="qopenglfunctions.html#glClear">glClear</a>() or <a href="qopenglfunctions.html#glDrawArrays">glDrawArrays</a>(), can be called also directly, as long as the application links to the platform-specific OpenGL library, calling them via <a href="qopenglfunctions.html">QOpenGLFunctions</a> enables the possibility of dynamically loading the OpenGL implementation.</p>
<p>The <a href="qopenglfunctions.html#hasOpenGLFeature">hasOpenGLFeature</a>() and <a href="qopenglfunctions.html#openGLFeatures">openGLFeatures</a>() 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:</p>
<pre class="cpp">
<span class="type"><a href="qopenglfunctions.html#QOpenGLFunctions">QOpenGLFunctions</a></span> funcs(<span class="type"><a href="qopenglcontext.html">QOpenGLContext</a></span><span class="operator">::</span>currentContext());
bool npot <span class="operator">=</span> funcs<span class="operator">.</span>hasOpenGLFeature(<span class="type"><a href="qopenglfunctions.html#QOpenGLFunctions">QOpenGLFunctions</a></span><span class="operator">::</span>NPOTTextures);
</pre>
