241 \class QMimeDatabase-
242 \inmodule QtCore-
243 \brief The QMimeDatabase class maintains a database of MIME types.-
244-
245 \since 5.0-
246-
247 The MIME type database is provided by the freedesktop.org shared-mime-info-
248 project. If the MIME type database cannot be found on the system, as is the case-
249 on most Windows, \macos, and iOS systems, Qt will use its own copy of it.-
250-
251 Applications which want to define custom MIME types need to install an-
252 XML file into the locations searched for MIME definitions.-
253 These locations can be queried with-
254 \code-
255 QStandardPaths::locateAll(QStandardPaths::GenericDataLocation, QLatin1String("mime/packages"),-
256 QStandardPaths::LocateDirectory);-
257 \endcode-
258 On a typical Unix system, this will be /usr/share/mime/packages/, but it is also-
259 possible to extend the list of directories by setting the environment variable-
260 \c XDG_DATA_DIRS. For instance adding /opt/myapp/share to \c XDG_DATA_DIRS will result-
261 in /opt/myapp/share/mime/packages/ being searched for MIME definitions.-
262-
263 Here is an example of MIME XML:-
264 \code-
265 <?xml version="1.0" encoding="UTF-8"?>-
266 <mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">-
267 <mime-type type="application/vnd.qt.qmakeprofile">-
268 <comment xml:lang="en">Qt qmake Profile</comment>-
269 <glob pattern="*.pro" weight="50"/>-
270 </mime-type>-
271 </mime-info>-
272 \endcode-
273-
274 For more details about the syntax of XML MIME definitions, including defining-
275 "magic" in order to detect MIME types based on data as well, read the-
276 Shared Mime Info specification at-
277 http://standards.freedesktop.org/shared-mime-info-spec/shared-mime-info-spec-latest.html-
278-
279 On Unix systems, a binary cache is used for more performance. This cache is generated-
280 by the command "update-mime-database path", where path would be /opt/myapp/share/mime-
281 in the above example. Make sure to run this command when installing the MIME type-
282 definition file.-

295 It is perfectly OK to create an instance of QMimeDatabase every time you need to-
296 perform a lookup.-
297 The parsing of mimetypes is done on demand (when shared-mime-info is installed)-
298 or when the very first instance is constructed (when parsing XML files directly).-

327-
328 A valid MIME type is always returned.-
329-
330 The default matching algorithm looks at both the file name and the file-
331 contents, if necessary. The file extension has priority over the contents,-
332 but the contents will be used if the file extension is unknown, or-
333 matches multiple MIME types.-
334 If \a fileInfo is a Unix symbolic link, the file that it refers to-
335 will be used instead.-
336 If the file doesn't match any known pattern or data, the default MIME type-
337 (application/octet-stream) is returned.-
338-
339 When \a mode is set to MatchExtension, only the file name is used, not-
340 the file contents. The file doesn't even have to exist. If the file name-
341 doesn't match any known pattern, the default MIME type (application/octet-stream)-
342 is returned.-
343 If multiple MIME types match this file, the first one (alphabetically) is returned.-
344-
345 When \a mode is set to MatchContent, and the file is readable, only the-
346 file contents are used to determine the MIME type. This is equivalent to-
347 calling mimeTypeForData with a QFile as input device.-
