[−][src]Struct qt_gui::QOpenGLShader
The QOpenGLShader class allows OpenGL shaders to be compiled.
C++ class: QOpenGLShader
.
The QOpenGLShader class allows OpenGL shaders to be compiled.
This class supports shaders written in the OpenGL Shading Language (GLSL) and in the OpenGL/ES Shading Language (GLSL/ES).
QOpenGLShader and QOpenGLShaderProgram shelter the programmer from the details of compiling and linking vertex and fragment shaders.
