Subject: [PATCH 1/1] Properly check which OpenGL features are supported
|
|
|
|
QOpenGLShaderProgram::hasOpenGLShaderPrograms tests whether
|
|
QOpenGLFunctions::Shaders is provided for the given context. As the
|
|
initialization code assumed OpenGL 2 this always was true. But
|
|
unfortunately we still cannot assume that OpenGL 2 is universally
|
|
supported. E.g. indirect rendering (no matter how bad that idea is)
|
|
does not support OpenGL 2 on all hardware and the Shader related
|
|
extensions are not available.
|
|
|
|
This change makes sure that only when OpenGL 2 is available the
|
|
features provided by OpenGL 2 are enabled. If OpenGL 2 is not
|
|
available the extensions are tested. The checks are slightly
|
|
reordered to not do the extension tests at all if OpenGL 2 is
|
|
available.
|
