<p>This class supports shaders written in the OpenGL Shading Language (GLSL) and in the OpenGL/ES Shading Language (GLSL/ES).</p>
<p>QGLShader and <a href="qglshaderprogram.html">QGLShaderProgram</a> shelter the programmer from the details of compiling and linking vertex and fragment shaders.</p>

<p>The ShaderType type is a typedef for <a href="qflags.html">QFlags</a><ShaderTypeBit>. It stores an OR combination of ShaderTypeBit values.</p>
