156 \class QResource -

157 \inmodule QtCore -

158 \brief The QResource class provides an interface for reading directly from resources. -

159 -

160 \ingroup io -

161 -

162 \reentrant -

163 \since 4.2 -

164 -

165 QResource is an object that represents a set of data (and possibly -

166 children) relating to a single resource entity. QResource gives direct -

167 access to the bytes in their raw format. In this way direct access -

168 allows reading data without buffer copying or indirection. Indirection -

169 is often useful when interacting with the resource entity as if it is a -

170 file, this can be achieved with QFile. The data and children behind a -

171 QResource are normally compiled into an application/library, but it is -

172 also possible to load a resource at runtime. When loaded at run time -

173 the resource file will be loaded as one big set of data and then given -

174 out in pieces via references into the resource tree. -

175 -

176 A QResource can either be loaded with an absolute path, either treated -

177 as a file system rooted with a \c{/} character, or in resource notation -

178 rooted with a \c{:} character. A relative resource can also be opened -

179 which will be found in the list of paths returned by QDir::searchPaths(). -

180 -

181 A QResource that is representing a file will have data backing it, this -

182 data can possibly be compressed, in which case qUncompress() must be -

183 used to access the real data; this happens implicitly when accessed -

184 through a QFile. A QResource that is representing a directory will have -

185 only children and no data. -

186 -

187 \section1 Dynamic Resource Loading -

188 -

189 A resource can be left out of an application's binary and loaded when -

190 it is needed at run-time by using the registerResource() function. The -

191 resource file passed into registerResource() must be a binary resource -

192 as created by rcc. Further information about binary resources can be -

193 found in \l{The Qt Resource System} documentation. -

194 -

195 This can often be useful when loading a large set of application icons -

196 that may change based on a setting, or that can be edited by a user and -

197 later recreated. The resource is immediately loaded into memory, either -

198 as a result of a single file read operation, or as a memory mapped file. -

199 -

200 This approach can prove to be a significant performance gain as only a -

201 single file will be loaded, and pieces of data will be given out via the -

202 path requested in setFileName(). -

203 -

204 The unregisterResource() function removes a reference to a particular -

205 file. If there are QResource objects that currently reference resources related -

206 to the unregistered file, they will continue to be valid but the resource -

207 file itself will be removed from the resource roots, and thus no further -

208 QResource can be created pointing into this resource data. The resource -

209 itself will be unmapped from memory when the last QResource that points -

210 to it is destroyed. -
