The FileManager service monitors a set of IFile's. Plugins should register files they work with at the service. The files the IFile's point to will be monitored at filesystem level. If a file changes, the status of the IFile's will be adjusted accordingly. Furthermore, on application exit the user will be asked to save all modified files. Different IFile objects in the set can point to the same file in the filesystem. The monitoring for a IFile can be blocked by blockFileChange(), and enabled again by unblockFileChange(). The functions expectFileChange() and unexpectFileChange() mark a file change as expected. On expected file changes all IFile objects are notified to reload themselves. The FileManager service also provides two convenience methods for saving files: saveModifiedFiles() and saveModifiedFilesSilently(). Both take a list of FileInterfaces as an argument, and return the list of files which were _not_ saved. The service also manages the list of recent files to be shown to the user (see addToRecentFiles() and recentFiles()). */ static const char settingsGroupC[] = "RecentFiles"; static const char filesKeyC[] = "Files"; static const char editorsKeyC[] = "EditorIds"; static const char directoryGroupC[] = "Directories"; static const char projectDirectoryKeyC[] = "Projects"; static const char useProjectDirectoryKeyC[] = "UseProjectsDirectory"; namespace Core { namespace Internal { struct FileStateItem { QDateTime modified; QFile::Permissions permissions; }; struct FileState { QMap lastUpdatedState; FileStateItem expected; }; struct FileManagerPrivate { explicit FileManagerPrivate(FileManager *q, QMainWindow *mw); QFileSystemWatcher *fileWatcher(); QFileSystemWatcher *linkWatcher(); static FileManager *m_instance; QMap m_states; QSet m_changedFiles; QList m_filesWithoutWatch; QMap m_filesWithWatch; QSet m_expectedFileNames; QList m_recentFiles; static const int m_maxRecentFiles = 7; QString m_currentFile; QMainWindow *m_mainWindow; QFileSystemWatcher *m_fileWatcher; // Delayed creation.
