Detailed Description

\inmodule QtOpenGL

Since: 5.1

The QOpenGLVersionProfile class represents the version and if applicable the profile of an OpenGL context.

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.

Constructor & Destructor Documentation

◆ QOpenGLVersionProfile() [1/3]

QOpenGLVersionProfile::QOpenGLVersionProfile ( )

Creates a default invalid QOpenGLVersionProfile object.

Definition at line 41 of file qopenglversionprofile.cpp.

◆ QOpenGLVersionProfile() [2/3]

QOpenGLVersionProfile::QOpenGLVersionProfile ( const QSurfaceFormat & format )

explicit

Creates a QOpenGLVersionProfile object initialised with the version and profile from format.

Definition at line 50 of file qopenglversionprofile.cpp.

◆ QOpenGLVersionProfile() [3/3]

QOpenGLVersionProfile::QOpenGLVersionProfile ( const QOpenGLVersionProfile & other )

Constructs a copy of other.

Definition at line 61 of file qopenglversionprofile.cpp.

◆ ~QOpenGLVersionProfile()

QOpenGLVersionProfile::~QOpenGLVersionProfile ( )

Destroys the QOpenGLVersionProfile object.

Definition at line 70 of file qopenglversionprofile.cpp.

Member Function Documentation

◆ hasProfiles()

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(), version()

Definition at line 135 of file qopenglversionprofile.cpp.

◆ isLegacyVersion()

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.

Definition at line 145 of file qopenglversionprofile.cpp.

◆ isValid()

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(), version()

Definition at line 156 of file qopenglversionprofile.cpp.

◆ operator=()

QOpenGLVersionProfile & QOpenGLVersionProfile::operator= ( const QOpenGLVersionProfile & rhs )

Assigns the version and profile of rhs to this QOpenGLVersionProfile object.

Definition at line 78 of file qopenglversionprofile.cpp.

◆ profile()

QSurfaceFormat::OpenGLContextProfile QOpenGLVersionProfile::profile ( ) const

Returns the OpenGL profile.

Only makes sense if profiles are supported by this version.

See also: setProfile()

Definition at line 113 of file qopenglversionprofile.cpp.

◆ 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()

Definition at line 124 of file qopenglversionprofile.cpp.

◆ setVersion()

void QOpenGLVersionProfile::setVersion	(	int	majorVersion,
		int	minorVersion )

Sets the major and minor version numbers to majorVersion and minorVersion respectively.

See also: version()

Definition at line 102 of file qopenglversionprofile.cpp.

◆ version()

std::pair< int, int > QOpenGLVersionProfile::version ( ) const

Returns a std::pair<int,int> where the components represent the major and minor OpenGL version numbers respectively.

See also: setVersion()

Definition at line 92 of file qopenglversionprofile.cpp.

◆ operator!=

bool operator!=	(	const QOpenGLVersionProfile &	lhs,
		const QOpenGLVersionProfile &	rhs )
