138 \class QAbstractOpenGLFunctions -

139 \inmodule QtGui -

140 \since 5.1 -

141 \brief The QAbstractOpenGLFunctions class is the base class of a family of -

142 classes that expose all functions for each OpenGL version and -

143 profile. -

144 -

145 OpenGL implementations on different platforms are able to link to a variable -

146 number of OpenGL functions depending upon the OpenGL ABI on that platform. -

147 For example, on Microsoft Windows only functions up to those in OpenGL 1.1 -

148 can be linked to at build time. All other functions must be resolved at -

149 runtime. The traditional solution to this has been to use either -

150 QOpenGLContext::getProcAddress() or QOpenGLFunctions. The former is tedious -

151 and error prone and means dealing directly with function pointers. The -

152 latter only exposes those functions common to OpenGL ES 2 and desktop -

153 OpenGL. There is however much new OpenGL functionality that is useful when -

154 writing real world OpenGL applications. -

155 -

156 Qt now provides a family of classes which all inherit from -

157 QAbstractOpenGLFunctions which expose every core OpenGL function by way of a -

158 corresponding member function. There is a class for every valid combination -

159 of OpenGL version and profile. Each class follows the naming convention: -

160 \badcode -

161 QOpenGLFunctions_<MAJOR VERSION>_<MINOR VERSION>[_PROFILE] -

162 \endcode -

163 -

164 For OpenGL versions 1.0 through to 3.0 there are no profiles, leading to the -

165 classes: -

166 -

167 \list -

168 \li QOpenGLFunctions_1_0 -

169 \li QOpenGLFunctions_1_1 -

170 \li QOpenGLFunctions_1_2 -

171 \li QOpenGLFunctions_1_3 -

172 \li QOpenGLFunctions_1_4 -

173 \li QOpenGLFunctions_1_5 -

174 \li QOpenGLFunctions_2_0 -

175 \li QOpenGLFunctions_2_1 -

176 \li QOpenGLFunctions_3_0 -

177 \endlist -

178 -

179 where each class inherits from QAbstractOpenGLFunctions. -

180 -

181 OpenGL version 3.1 removed many deprecated functions leading to a much -

182 simpler and generic API. -

183 -

184 With OpenGL 3.2 the concept of profiles was introduced. Two profiles are -

185 currently defined for OpenGL: Core and Compatibility. -

186 -

187 The Core profile does not include any of the functions that were removed -

188 in OpenGL 3.1. The Compatibility profile contains all functions in the -

189 Core profile of the same version plus all of the functions that were -

190 removed in OpenGL 3.1. In this way the Compatibility profile classes allow -

191 use of newer OpenGL functionality but also allows you to keep using your -

192 legacy OpenGL code. For new OpenGL code the Core profile should be -

193 preferred. -

194 -

195 Please note that some vendors, notably Apple, do not implement the -

196 Compatibility profile. Therefore if you wish to target new OpenGL features -

197 on \macos then you should ensure that you request a Core profile context via -

198 QSurfaceFormat::setProfile(). -

199 -

200 Qt provides classes for all version and Core and Compatibility profile -

201 combinations. The classes for OpenGL versions 3.1 through to 4.3 are: -

202 -

203 \list -

204 \li QOpenGLFunctions_3_1 -

205 \li QOpenGLFunctions_3_2_Core -

206 \li QOpenGLFunctions_3_2_Compatibility -

207 \li QOpenGLFunctions_3_3_Core -

208 \li QOpenGLFunctions_3_3_Compatibility -

209 \li QOpenGLFunctions_4_0_Core -

210 \li QOpenGLFunctions_4_0_Compatibility -

211 \li QOpenGLFunctions_4_1_Core -

212 \li QOpenGLFunctions_4_1_Compatibility -

213 \li QOpenGLFunctions_4_2_Core -

214 \li QOpenGLFunctions_4_2_Compatibility -

215 \li QOpenGLFunctions_4_3_Core -

216 \li QOpenGLFunctions_4_3_Compatibility -

217 \endlist -

218 -

219 where each class inherits from QAbstractOpenGLFunctions. -

220 -

221 A pointer to an object of the class corresponding to the version and -

222 profile of OpenGL in use can be obtained from -

223 QOpenGLContext::versionFunctions(). If obtained in this way, note that -

224 the QOpenGLContext retains ownership of the object. This is so that only -

225 one instance need be created. -

226 -

227 Before calling any of the exposed OpenGL functions you must ensure that the -

228 object has resolved the function pointers to the OpenGL functions. This -

229 only needs to be done once per instance with initializeOpenGLFunctions(). -

230 Once initialized, the object can be used to call any OpenGL function for -

231 the corresponding version and profile. Note that initializeOpenGLFunctions() -

232 can fail in some circumstances so check the return value. Situations in -

233 which initialization can fail are if you have a functions object for a version -

234 or profile that contains functions that are not part of the context being -

235 used to resolve the function pointers. -

236 -

237 If you exclusively use function objects then you will get compile time -

238 errors if you attempt to use a function not included in that version and -

239 profile. This is obviously a lot easier to debug than undefined behavior -

240 at run time. -
