詳細描述

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.

QOpenGLVersionProfile:: QOpenGLVersionProfile (const QOpenGLVersionProfile & other )

構造副本為 other .

QOpenGLVersionProfile:: QOpenGLVersionProfile (const QSurfaceFormat & format )

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

QOpenGLVersionProfile:: QOpenGLVersionProfile ()

Creates a default invalid QOpenGLVersionProfile object.

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

Assigns the version and profile of rhs 到此 QOpenGLVersionProfile 對象。

QOpenGLVersionProfile:: ~QOpenGLVersionProfile ()

銷毀 QOpenGLVersionProfile 對象。

bool QOpenGLVersionProfile:: hasProfiles () const

返迴 true if profiles are supported by the OpenGL version returned by version (). Only OpenGL versions >= 3.2 support profiles.

另請參閱 profile () 和 version ().

bool QOpenGLVersionProfile:: isLegacyVersion () const

返迴 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

返迴 true if the version number is valid. Note that for a default constructed QOpenGLVersionProfile object this function will return false .

QSurfaceFormat::OpenGLContextProfile QOpenGLVersionProfile:: profile () const

Returns the OpenGL profile. Only makes sense if profiles are supported by this version.

另請參閱 setProfile ().

void QOpenGLVersionProfile:: setProfile ( QSurfaceFormat::OpenGLContextProfile profile )

Sets the OpenGL profile profile . Only makes sense if profiles are supported by this version.

另請參閱 profile ().

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

Sets the major and minor version numbers to majorVersion and minorVersion 分彆。

另請參閱 version ().

QPair < int , int > QOpenGLVersionProfile:: version () const

返迴 QPair <int,int> where the components represent the major and minor OpenGL version numbers respectively.
