Detailed Description
An object of this class can be passed to QOpenGLContext::versionFunctions() to request a functions object for a specific version and profile of OpenGL.
It also contains some helper functions to check if a version supports profiles or is a legacy version.
Member Function Documentation
QOpenGLVersionProfile::QOpenGLVersionProfile()
Creates a default invalid QOpenGLVersionProfile object.
[explicit] QOpenGLVersionProfile::QOpenGLVersionProfile(const QSurfaceFormat &format)
Creates a QOpenGLVersionProfile object initialised with the version and profile from format.
QOpenGLVersionProfile::QOpenGLVersionProfile(const QOpenGLVersionProfile &other)
Constructs a copy of other.
[noexcept] QOpenGLVersionProfile::~QOpenGLVersionProfile()
Destroys the QOpenGLVersionProfile object.
bool QOpenGLVersionProfile::hasProfiles() const
Returns true if profiles are supported by the OpenGL version returned by version(). Only OpenGL versions >= 3.2 support profiles.
See also profile() and version().
bool QOpenGLVersionProfile::isLegacyVersion() const
Returns true is the OpenGL version returned by version() contains deprecated functions and does not support profiles i.e. if the OpenGL version is <= 3.1.
bool QOpenGLVersionProfile::isValid() const
Returns true if the version number is valid. Note that for a default constructed QOpenGLVersionProfile object this function will return false.
See also setVersion() and version().
QSurfaceFormat::OpenGLContextProfile QOpenGLVersionProfile::profile() const
Returns the OpenGL profile. Only makes sense if profiles are supported by this version.
See also setProfile().
void QOpenGLVersionProfile::setProfile(QSurfaceFormat::OpenGLContextProfile profile)
Sets the OpenGL profile profile. Only makes sense if profiles are supported by this version.
See also profile().
void QOpenGLVersionProfile::setVersion(int majorVersion, int minorVersion)
Sets the major and minor version numbers to majorVersion and minorVersion respectively.
See also version().
QPair<int, int> QOpenGLVersionProfile::version() const
Returns a QPair<int,int> where the components represent the major and minor OpenGL version numbers respectively.
See also setVersion().
QOpenGLVersionProfile &QOpenGLVersionProfile::operator=(const QOpenGLVersionProfile &rhs)
Assigns the version and profile of rhs to this QOpenGLVersionProfile object.
