106 \class QNetworkConfigurationManager -

107 -

108 \brief The QNetworkConfigurationManager class manages the network configurations provided -

109 by the system. -

110 -

111 \since 4.7 -

112 -

113 \inmodule QtNetwork -

114 \ingroup network -

115 -

116 QNetworkConfigurationManager provides access to the network configurations known to the system and -

117 enables applications to detect the system capabilities (with regards to network sessions) at runtime. -

118 -

119 A QNetworkConfiguration abstracts a set of configuration options describing how a -

120 network interface has to be configured to connect to a particular target network. -

121 QNetworkConfigurationManager maintains and updates the global list of -

122 QNetworkConfigurations. Applications can access and filter this list via -

123 allConfigurations(). If a new configuration is added or an existing one is removed or changed -

124 the configurationAdded(), configurationRemoved() and configurationChanged() signals are emitted -

125 respectively. -

126 -

127 The defaultConfiguration() can be used when intending to immediately create a new -

128 network session without caring about the particular configuration. It returns -

129 a \l QNetworkConfiguration::Discovered configuration. If there are not any -

130 discovered ones an invalid configuration is returned. -

131 -

132 Some configuration updates may require some time to perform updates. A WLAN scan is -

133 such an example. Unless the platform performs internal updates it may be required to -

134 manually trigger configuration updates via QNetworkConfigurationManager::updateConfigurations(). -

135 The completion of the update process is indicated by emitting the updateCompleted() -

136 signal. The update process ensures that every existing QNetworkConfiguration instance -

137 is updated. There is no need to ask for a renewed configuration list via allConfigurations(). -

138 -

139 \sa QNetworkConfiguration -

140 */ -

141 -

142 /*! -

143 \fn void QNetworkConfigurationManager::configurationAdded(const QNetworkConfiguration &config) -

144 -

145 This signal is emitted whenever a new network configuration is added to the system. The new -

146 configuration is specified by \a config. -

147 */ -

148 -

149 /*! -

150 \fn void QNetworkConfigurationManager::configurationRemoved(const QNetworkConfiguration &config) -

151 -

152 This signal is emitted when a configuration is about to be removed from the system. The removed -

153 configuration, specified by \a config, is invalid but retains name and identifier. -

154 */ -

155 -

156 /*! -

157 \fn void QNetworkConfigurationManager::updateCompleted() -

158 -

159 This signal is emitted when the configuration update has been completed. Such an update can -

160 be initiated via \l updateConfigurations(). -

161 */ -

162 -

163 /*! \fn void QNetworkConfigurationManager::configurationChanged(const QNetworkConfiguration &config) -

164 -

165 This signal is emitted when the \l {QNetworkConfiguration::state()}{state} of \a config changes. -

166 */ -

167 -

168 /*! -

169 \fn void QNetworkConfigurationManager::onlineStateChanged(bool isOnline) -

170 -

171 This signal is emitted when the device changes from online to offline mode or vice versa. -

172 \a isOnline represents the new state of the device. -

173 -

174 The state is considered to be online for as long as -

175 \l{allConfigurations()}{allConfigurations}(QNetworkConfiguration::Active) returns a list with -

176 at least one entry. -

177 */ -

178 -

179 /*! -

180 \enum QNetworkConfigurationManager::Capability -

181 -

182 Specifies the system capabilities of the bearer API. The possible values are: -

183 -

184 \value CanStartAndStopInterfaces Network sessions and their underlying access points can be -

185 started and stopped. If this flag is not set QNetworkSession -

186 can only monitor but not influence the state of access points. -

187 On some platforms this feature may require elevated user -

188 permissions. This option is platform specific and may not -

189 always be available. -

190 \value DirectConnectionRouting Network sessions and their sockets can be bound to a -

191 particular network interface. Any packet that passes through -

192 the socket goes to the specified network interface and thus -

193 disregards standard routing table entries. This may be useful -

194 when two interfaces can reach overlapping IP ranges or an -

195 application has specific needs in regards to target networks. -

196 This option is platform specific and may not always be -

197 available. -

198 \value SystemSessionSupport If this flag is set the underlying platform ensures that a -

199 network interface is not shut down until the last network -

200 session has been \l{QNetworkSession::close()}{closed()}. This -

201 works across multiple processes. If the platform session -

202 support is missing this API can only ensure the above behavior -

203 for network sessions within the same process. -

204 In general mobile platforms have such -

205 support whereas most desktop platform lack this capability. -

206 \value ApplicationLevelRoaming The system gives applications control over the systems roaming -

207 behavior. Applications can initiate roaming (in case the -

208 current link is not suitable) and are consulted if the system -

209 has identified a more suitable access point. -

210 \value ForcedRoaming The system disconnects an existing access point and reconnects -

211 via a more suitable one. The application does not have any -

212 control over this process and has to reconnect its active -

213 sockets. -

214 \value DataStatistics If this flag is set QNetworkSession can provide statistics -

215 about transmitted and received data. -

216 \value NetworkSessionRequired If this flag is set the platform requires that a network -

217 session is created before network operations can be performed. -

218 */ -

219 -

220 /*! -

221 Constructs a QNetworkConfigurationManager with the given \a parent. -

222 -

223 Note that to ensure a valid list of current configurations immediately available, updating -

224 is done during construction which causes some delay. -

275 Returns the list of configurations which comply with the given \a filter. -

276 -

277 By default this function returns all (defined and undefined) configurations. -

278 -

279 A wireless network with a particular SSID may only be accessible in a -

280 certain area despite the fact that the system has a valid configuration -

281 for it. Therefore the filter flag may be used to limit the list to -

282 discovered and possibly connected configurations only. -

283 -

284 If \a filter is set to zero this function returns all possible configurations. -

285 -

286 Note that this function returns the states for all configurations as they are known at -

287 the time of this function call. If for instance a configuration of type WLAN is defined -

288 the system may have to perform a WLAN scan in order to determine whether it is -

289 actually available. To obtain the most accurate state updateConfigurations() should -

290 be used to update each configuration's state. Note that such an update may require -

291 some time. It's completion is signalled by updateCompleted(). In the absence of a -

292 configuration update this function returns the best estimate at the time of the call. -

293 Therefore, if WLAN configurations are of interest, it is recommended that -

294 updateConfigurations() is called once after QNetworkConfigurationManager -

295 instantiation (WLAN scans are too time consuming to perform in constructor). -

296 After this the data is kept automatically up-to-date as the system reports -

297 any changes. -
