FileMananger class is the main communication class to talk to theremote PDA. The FileSystemOperator class allows for transferingsettings files, application files, and user files.<p> Settings files are probably stored in an rc file. One settings filemay be shared by many applications. For example, there may be onesettings file that contains PDA specific information such as thelocal time zone, language, and display options.<p> To do: Docs about app files...<p> To do: Docs about user data files...<p> The FileSystemOperator class provides send, retrieve, remove and listmethods for settings, application data, and user data. The sendmethods send data from the local computer to the remote computer(eg. from desktop to PDA). The retrieve methods retrieve a file fromthe PDA and place it in the appropriate local directory. The removemethods removes the files on both the local and remote file systems.The list methods provide a listing on the remote file systems.<p> The FileSystemOperator class verifies the locally directory existsbefore retrieving files from the remote machine and that remotedirectories exist beforing sending files. Since remote directorytrees may need to be created on the remote machine, there may need tobe several mkdir operations before actually copying the local file tothe remote directory. To know when the send copy commands areactually started and to connect with the associatedQNetworkOperation, connect to the startSend signal.<p> The FileSystemOperator class uses the QUrlOperator to actuallyperform the ftp copy, remove, and file listing commands. The callerof the class can connect to the QUrlOperator signals for feedback ofeach call.<p> The FileSystemOperator class places the files in their appropriatedirectories on both the PDA and the local side. If the directoriesdon't exist on either side, then the directories are created.<p>See also <a href="qtopiadesktop.html">Qtopia Desktop Classes</a>.<hr><h2>Member Function Documentation</h2><h3 class=fn><a name="FileSystemOperator"></a>FileSystemOperator::FileSystemOperator ( PalmtopConnection * con )</h3>Constructs a FileSystemOperator object using PalmtopConnection <em>con</em><h3 class=fn>bool <a name="copyLocalFile"></a>FileSystemOperator::copyLocalFile ( const QString & source, const QStringList & destFilenames )<tt> [static]</tt></h3>Copy local file <em>source</em> to destination files <em>destFilenames</em>.<h3 class=fn>QString <a name="dirPath"></a>FileSystemOperator::dirPath ( const QString & filePath )<tt> [static]</tt></h3>Returns the directory path of the absolute file path <em>filePath</em>.<h3 class=fn>void <a name="done"></a>FileSystemOperator::done ( int totalNumBytes )<tt> [signal]</tt></h3> <p> This signal is emitted when the transfer currently processed by the FileSystemOperatoris completed. <em>totalNumBytes</em> is the total number of bytes transfered.<h3 class=fn>bool <a name="ensureLocalPath"></a>FileSystemOperator::ensureLocalPath ( const QString & localPath )<tt> [static]</tt></h3>Ensures that <em>localPath</em> exists.
