Using Evolution This dialog contains four tabs, which allow you to customize the contents of the Evolution Summary screen: Tab Description Mail Allows you to add shortcuts to each of your local mail folders (including subfolders) - including the Inbox, Outbox, Sent, and Drafts folders, and any other folders you create using the Inbox mode. If you add a shortcut to a folder, the Summary also shows you a count of the number of items in that folder. News Feeds Allows you to add links to news feeds. The News Feeds tab contains a number of predefined news feeds to choose from - the Red Hat Linux Update Watch (https://rhn.redhat.com/rpc/recent-errata.pxt) is displayed by default. You can also use the News Feeds tab to create your own. Weather Allows you to retrieve the current weather forecasts from a recognized source. For example, the Met Office (in the UK) is used as the source for weather forecasts most of the main cities within the UK. Schedule Allows you to manage the display of calendar and task summaries in the Summary display. You can choose how many days of your calendar to be displayed at once (choose from one day, five days, one week, or one month). You can also choose to whether to display all tasks in the Summary, or only those tasks that are “due today”. The Inbox Feature The Inbox screen provides an interface not only to your Inbox folder, but to all your local mail folders. When you first open the Inbox screen, you get to see the Inbox folder, with a list of messages shown in the top panel and the content of the currently selected message shown underneath in the preview panel. The toolbar contains shortcuts to the most popular features - creating, replying, and deleting messages, printing, navigation, and so on. The folder bar is a particularly useful feature that’s not shown by default. To make it appear, select View | Folder Bar: 143

Using Evolution The layout of the window consists of the usual menu bar and a context sensitive toolbar. The toolbar’s icons reflect the application’s current mode (Summary, Inbox, Calendar, Tasks, or Contacts). These modes are accessed via the shortcut toolbar that runs down the left hand side of the application: The Summary feature provides a summary screen, similar to Outlook’s Today screen. It provides a summary of your Mail Box, indicating the number of e-mail messages in your Inbox and Outbox with counters for each. A list of current Appointments and Tasks is shown along with the ability to capture the current Weather forecast and News Feeds from the Internet. The Inbox (shown above) provides access to your e-mail account, allowing you to send, receive, and manage your e-mails using such features and folders. The Calendar allows you to manage your schedule, adding forthcoming appointments between one or more people and attaching reminders so you don’t forget! The Tasks feature provides a simple task database, allowing you to record tasks and assign Due Dates. In addition, you can categorize your tasks for more flexibility when managing them. The Contacts feature allows you to store your contacts in an address book, which may then be used when sending e-mails. However, it allows you to store far more information than simply an e-mail address such as their address, web pages, a variety of telephone numbers, company information, and more! Again, we’ll avoid trying to provide a user guide here; that would take too much room, and the online documentation is more than sufficient to take you through the details of individual tasks. Instead, we’ll concentrate on the key features of the application, we’ll note some similarities with Microsoft Outlook, and we’ll also cover some of the features for interoperability with other applications (particularly Microsoft Outlook). The Summary Feature As mentioned, this feature is very similar to the Today screen in Microsoft Outlook, or the Summary screen in Microsoft Outlook Express. It summarizes the information held within the application, and includes useful features for gathering information from various sources on the Internet. To modify the settings that apply to this screen, you can use Tools | Settings to bring up the Evolution Settings dialog, and then select the Summary Preferences tab: 142

Using Evolution Alternatively, you can set up your mailbox properties once the application has started properly. To do this, select Tools | Settings (this is the starting point for changing most of Evolution’s settings), and then select the Mail Accounts tab, which allows you to add new accounts and edit the properties of your existing accounts: The wizard guides you through process of entering the information that is provided by your ISP to gain access to your Internet account and e-mail subscription: your name, e-mail address, and the name of the server and username assigned by your ISP. Using Evolution Selecting this option will start the setup wizard, and when the wizard is complete you’ll see the Summary screen by default. You can move to other areas of the application by selecting the icons on the left hand side of the window. For example, selecting the Inbox icon will display the following screen: 141

Personal Information Management When you’ve done that, you can sign in and start chatting: The latest updates, documentation and additional plug-ins to extend the functionality of GAIM can be found at its web site at http://gaim.sourceforge.net. Personal Information Management As if the Mozilla plug-ins for tasks such as e-mail management weren’t enough, an application to manage e-mails, contacts and related things is available in the form of Ximian’s Evolution. The Evolution application is a groupware program, similar to Microsoft Outlook, that provides access to personal information such as e-mail, a calendar, contacts, and so on. Management of this type of information is often known as personal information management (or PIM). Programs like Evolution (and Outlook) allow you to manage all of this personal information within a single application. Installing Evolution If you look in the RPM GUI, you’ll find the Evolution package under the Graphical Internet package group (which is within the Applications category). In fact, it is installed by default as part of the default installation of Red Hat Linux 9 excluding the Server edition for obvious reasons. Once installed, you can start the Evolution application by selecting Main Menu | Internet | Evolution Email, or by clicking the Evolution Email shortcut that you’ll find on the taskbar at the bottom left corner of the desktop (near the Main Menu button). Setting up Evolution If you are starting Evolution for the first time, the setup wizard will guide you through completing the information to establish a connection with your mail server through your Internet Service Provider (ISP). The screen below shows one of the early screens in the Evolution Setup Assistant, which starts up the first time you run the application: 140

The Mozilla Web Browser The first thing to do (if you haven’t done so already) is create an account with an Internet messaging service (there are plenty around - MSN and Yahoo! are just two examples). Then, start GAIM (by selecting Main Menu | Internet | Instant Messenger or type gaim at the command line): By default, only two protocols are installed with GAIM - AIM/ICQ and TOC. It’s quite possible that your messaging service uses a different protocol - for example, MSN Messenger and Yahoo! both use their own protocols. GAIM supports many such protocols; to install the protocol support you need, click the Plugins button and use the Load option to load the plugins you require for each protocol: When you’ve done that, you can tell GAIM about your account - to do that, you click the Accounts button, and supply the information about your account and the protocol used. 139

The Mozilla Web Browser This has very similar functionality to that of Microsoft’s Outlook Express - providing folders for your e-mail and for any newsgroups that you’re subscribed to. By default, Mozilla includes support for Internet Security Standards such as SSL (Secure Sockets Layer), which provides encryption of information over the Internet. Let’s have a look at some of the specific interoperability features within Mozilla’s mail. Importing from Other Clients If you have been using another mail client such as Netscape Communicator, Microsoft Outlook, or Microsoft Outlook Express, you may import your mail messages into Mozilla mail by using the features provided from the Tools | Import menu option. This option presents you with the following dialog: This feature will guide you through the process of importing mail settings, and messages, or an address book from another mail client - you simply select the appropriate option and follow the wizard. It’s also possible to export an address book to a variety of formats (including Outlook and Outlook Express). To do this, select Window | Address Book, then the address book you want to export, and then click the Tools | Export menu option. The GAIM Instant Messenger Application So you can browse the Internet and correspond using e-mail; what about chatting? This technology has suffered from the number of different protocols used by different organizations for transmitting information. However, in true Linux tradition, GAIM is flexible enough to cope with this and offers an elegant solution. As we mentioned in Chapter 3, GAIM is a utility for supporting online chats; it’s similar to things like the AOL Instant Messenger application. It provides a single front-end for multiple protocols (including ICQ, IRC, and Yahoo) and so can interoperate with other Instant Messenger applications. 138

The Mozilla Web Browser The layout of the application is likely familiar to you. The menu bar contains all the familiar menus, and the navigation toolbar allows you to type in a URL, move back and forward between recently visited pages, reload a page, and stop a page from loading. The above screenshot also shows a personal toolbar folder, which contains shortcuts to your favorite websites - you can control the shortcuts on your personal toolbar folder by using the Manage Bookmarks option (which you’ll find under the Bookmarks menu): The features provided by Mozilla (and the look and feel of those features) will be familiar if you’ve used Internet Explorer, and more especially if you’ve used Netscape Navigator (because Mozilla and Navigator are derived from the same original source code). The Mozilla Mail Client In addition to its core functionality as a web browser, we can extend Mozilla’s base featureset by installing additional functionality (known as plug-ins) such as the Mozilla-based mail client. In fact, the mail client plug-in is installed as a default extension to Mozilla. The mail client is accessible from the Mozilla application by selecting the Window | Mail & Newsgroups option from the menu bar. When you first use this, you’ll be prompted to create a default account using the information provided by your ISP or network administrator. When you’ve successfully entered that information, the main application will start with the following screen: 137

Internet Applications Internet Applications The existence of the Internet is at the heart of many of Linux’s most exciting applications. Therefore, as promised, in this section we’ll take a look at Linux’s Internet-related applications. The default installation of Red Hat Linux 9 includes a number of applications contained in the Graphical Internet package. All these applications have a graphical user interface (GUI) to make the user’s life easier. The package group contains some 14 applications (of which eight are installed by default). In this section we will concentrate on just two of them: The Mozilla application - a web browser that provides similar functionality to Netscape’s Navigator or Microsoft’s Internet Explorer browsers. Mozilla is a fully functional web browser, and also supports extensions to add further functionality (such as mail). The GAIM client - an Instant Messaging client similar to Microsoft’s Instant Messenger and capable of interfacing with a number of messaging protocols (such as AIM, ICQ, Yahoo!, MSN, IRC, and others) used by various messaging clients. We’ll take a look at these applications in more detail, and discuss their history and interoperability features; and then you’ll be in a position to explore at your leisure. The Mozilla Web Browser The Netscape browser’s core source code, known as mozilla, was released to the public under the Netscape Public License (NPL) in 1998. The Mozilla project (a group set up to continue Netscape Communicator as an Open Source application) used this code as the basis for its own commercial-level browser. The current version of Mozilla is released under the NPL license for modifications of the core mozilla code and the Mozilla Public License (MPL) for any new additions. The Mozilla web browser is the primary browser for Red Hat Linux, and is an X Window System application that provides a very similar look and feel to the Netscape Navigator and Internet Explorer applications. To take a look, fire it up now by clicking the Web Browser icon on the bottom left of your desktop (next to the Main Menu button), or by selecting Main Menu | Internet | Mozilla Web Browser: 136

Using OpenImpress for Presentations Tools | Options dialog box, in the Spreadsheet | Calculate tab: Note the Search criteria = and <> must apply to whole cells option in this dialog. When this option is selected, OpenCalc handles searches in the same way as Microsoft Excel, in that the search criteria entered are specific and must match the whole cell. When the option is unselected, the search criteria are matched against any position within the cell. Using OpenImpress for Presentations OpenOffice’s OpenImpress (or Impress) application again provides many of the kind of features that you would expect of a commercial application, and is comparable with Microsoft’s PowerPoint, the presentation management application within Microsoft Office. The key features of OpenImpress include: Master templates Slide animation and transition effects Notes against slides Timing rehearsals OpenImpress supports compatibility with Microsoft’s PowerPoint, in its ability to load and save presentations and templates in PowerPoint’s file format (namely PowerPoint 97/2000/XP). There are a number of other applications installed within the OpenOffice suite that we haven’t covered in this chapter. It’s worth experimenting with the applications installed, to learn more about what they’re capable of doing - here’s a brief summary of each: The diagramming tool, Dia, is launched through Main Menu | Office | Dia Diagrams. This application is used for drawing diagrams based on a variety of templates - from simple boxes and lines to circuit diagrams. It’s very similar to a primitive version of Microsoft’s Visio diagram application. See http://www.lysator.liu.se/~alla/dia/dia.html for more information. The Draw application, launched via Main Menu | Office | Openoffice.org Draw, can be used to generate drawings that are of a more graphical nature. It allows you to insert clipart from its internal library or external sources. It draws its influence from Microsoft’s Draw application. The Printer Setup application (Main Menu | Office | Openoffice.org Printer Setup) simply allows you to confirm printer devices that may be available to you, and direct output from applications such as OpenOffice to your printers. Its closest Windows cousin is the Printers option found within the Windows Control Panel. 135

Using OpenCalc for Spreadsheets processing application. We won’t list them all here; like the other applications in the suite, it would warrant a book in its own right. However, we will highlight some of the key features included and also describe how interoperability with other applications such as Microsoft Office is achieved. Some of the key features present are: Styles and style galleries Thesaurus Spell checker Clipart Support for other file formats, such as Microsoft Word, StarWriter, and so on As we’ve seen, OpenWriter is compatible with Microsoft Word. In particular, it is capable of loading and saving documents and templates in a number of Word file formats, including Microsoft Word 97/2000/XP and Microsoft Word 6.0/95. You can load and save between OpenOffice’s native version and any of the other versions listed, simply by using the File | Open and File | Save dialogs. The File Type drop-down box allows you to choose the appropriate format: Using OpenCalc for Spreadsheets OpenOffice’s OpenCalc (or Calc) application again provides numerous features that you would expect of a commercial application and is comparable with Microsoft Excel, the spreadsheet application within Microsoft Office. Some of the key features present are: Ability to handle multiple spreadsheets simultaneously Embedded graphics and charts Cell security External data sources Data Pilot (this is similar to PivotTables in Excel) OpenCalc also supports compatibility with Excel, in its ability to load and save spreadsheets and templates in a number of Excel file formats, including Microsoft Excel 97/2000/XP and Microsoft Excel 4.x-5.0. Other interoperability features include the handling of VBA code and embedded objects (as we mentioned earlier in this chapter). There are other, more specific options that mimic the behavior of MS Excel, and help to make users with an MS Excel background feel more comfortable. One specific such option is the ability to indicate that OpenCalc’s searching capability should behave in the same manner as Excel’s. This option can be found in the 134
