QFileInfo:: QFileInfo(const QFileDevice & file)Ĭonstructs a new QFileInfo that gives information about file file. See also setFile(), isRelative(), QDir::setCurrent(), and QDir::isRelativePath(). The file can also include an absolute or relative path. QFileInfo:: QFileInfo(const QString & file)Ĭonstructs a new QFileInfo that gives information about the given file. Note that an empty QFileInfo object contain no file reference. Member Function Documentation QFileInfo:: QFileInfo() QFile), it's not possible to fully integrate the latter APIs with Android's MediaStore APIs. For more information, also see storage best practices. Aim to follow the Scoped storage guidelines, such as using app specific directories instead of other public external directories.Access permissions might be needed by prompting the user through the QFileDialog which implements Android's native file picker.On Android, some limitations apply when dealing with content URIs: If you want to make sure that all information is read from the file system, use stat(). If you want to switch off a QFileInfo's caching and force it to access the file system every time you request information from it call setCaching(false). Note: To speed up performance, QFileInfo caches information about the file.īecause files can be changed by other users or programs, or even by other parts of the same program, there is a function that refreshes the file information: refresh(). You can examine a file's permissions and ownership in a single statement using the permission() function. The file's ownership is available from owner(), ownerId(), group() and groupId(). Information about the file's access permissions is obtained with isReadable(), isWritable() and isExecutable(). The file's dates are returned by birthTime(), lastModified(), lastRead() and fileTime(). If you wish to use trailing separators in your own file info objects, just append one to the file name given to the constructors or setFile(). QFileInfo objects to directories created by Qt classes will not have a trailing file separator. The fileName()'s parts can be extracted with baseName(), suffix() or completeSuffix().
