-
- <s2 id=OVERVIEW>General Overview
-
- CDE Help is an online help system, primarily intended for OSF/Motif
- applications. The following sections provide a summary of major CDE Help
- features. (For more details, refer to "<xref DESIGN>.")
-
- <otherhead>Hyperlinks
-
- Hyperlinks are the key feature in a hypermedia system.
- CDE Help supports four types of hyperlinks:
-
- <list bullet>
-
- * <emph>Standard hypertext jumps<\emph> immediately move the reader to
- a different location within the online information. By default, these
- types of jumps replace the contents of the existing window. However,
- the author may specify jumps that should be displayed in a "new view."
- (For more detail, refer to "<xref HYPERTEXT>.")
-
- * <emph>Definition links<\emph> temporarily show the definition of a key
- word or phrase. Although intended for keyword-to-glossary lookup,
- definition links have many other useful applications. (For an example,
- refer to "<link hyperlink="Intromgr _HOMETOPIC" JumpNewView>Introducing the CDE Desktop.<\link>.")
-
- * <emph>Command links<\emph> execute an author-defined command to
- invoke an action beyond the domain of the help system. Any shell
- command can be executed, so this feature is really the "open door" to
- the outside world for CDE Help authors. (To try examples, refer to
- "<xref COMMANDS>.")
-
- * <emph>Application-defined links<\emph> (To try some examples, refer
- to "<xref COMMUNICATION>.")
-
- <\list>
-
- <otherhead>Embedded Graphics
-
- CDE Help supports the following graphics formats. To view samples
- of a few of these formats, refer to "<xref GRAPHICS>."
-
- <list bullet>
-
- * !!X Window Dump!! (xwd) color graphics. This format is
- created using the standard <computer>xwd<\computer> utility program.
- Many popular graphics tools for the X Window System also support this
- format.
-
- * !!X Pixmap!! (xpm) color graphics. This is an emerging
- standard format for multicolor icons.
-
- * <emph>X Bitmap<\emph> (bitmap) two-tone graphics. The foreground
- and background of these images tracks the foreground and background
- used to display text in the display area. This format can be created
- and edited using the standard <computer> bitmap<\computer> utility
- program.
-
- * <emph>TIFF<\emph> (tagged image file format) black and white and
- greyscale graphics. This is perhaps the most common format in the
- personal computer graphics industry.
-
- <\list>
-
-
- <otherhead>Interactive Keyword Index
-
- CDE Help's keyword index functions much like the index in a book,
- listing words the author marked as important. Unlike the index in a book,
- this online index accelerates the reader's ability to jump to references
- because each word or phrase is a link to the location (or list of
- locations) where it is used.
-
-
- <otherhead>Help Registration
-
- When an application is installed, it may install its help files in any
- location. Optionally, applications can participate in a "registration"
- process that enables two important features for online help:
-
- <list bullet>
-
- * <emph>Cross-application links<\emph> that allow hyperlinks to jump
- from one application's help to another's.
-
- * <emph>System-wide access to help<\emph> provided by the <link
- hyperlink="browser _HOMETOPIC" JumpNewView>CDE Help Manager<\link>.
-
- <\list>
-
- <note>
- See the <link dtappintegrate man>dtappintegrate Man Page<\link>
- for specific information on registration of application help volumes.
- <\note>
- <!-- HYPERTEXT -->
-
- <s2 id=HYPERTEXT>Hyperlinks for Navigation
-
- The "hyper" in hypermedia is what separates hypermedia systems
- from online documentation systems. Unlike books that have a linear
- organization, hyperlinks let authors create many different, nonlinear
- organizations, including "webs," "trees," "circles," and "chains."
-
- In CDE Help, the basis for all organizations is a hierarchy.
- However, authors can augment the structure by creating links between
- related topics that are in different branches of the hierarchy.
-
- <otherhead>Simple Jumps (Same Window)
-
- Most hyperlinks are simple jumps within the same application help. These
- simple jumps reuse the same window, overwriting the previous topic with
- each jump.
-
- <otherhead>Jumping to a New Window
-
- When an author creates a new link, she can specify that the link should
- open a new help window. The application is responsible for creating and
- managing the new window.
-
- <p gentity=SnapshotIcon glinktype=JumpNewView ghyperlink=HYPERTEXT>
- For example, this camera icon is a hyperlink to this topic on
- hypertext. However this link specifies that a new window is desired.
- Effectively, this link takes a "snapshot" of this window. You may use
- this snapshot link to create as many demo windows as you want. The demo
- will continue to run until you close the last one.
-
- <otherhead>Knowing Where You Are
-
- Near the top of the general help window is an indented list of
- topic titles. This list represents your current position (highlighted entry)
- with respect to its related topics.
-
- You can go directly to any of the related topics in the list by selecting its
- title.
-
- <otherhead>Knowing Where You've Been
-
- CDE Help keeps track of each topic you've viewed in each help
- window. To go back to previous topics, you can:
-
- <list bullet>
-
- * Choose Backtrack from the Navigate menu or from the pop-up menu in the
- dipslay area to immediately go back to the previous topic.
-
- * Choose History from the Search menu to display a list of all the topics
- you've viewed. To return to a topic, select its title in the list.
-
- <\list>
-
-
- <!-- DEFINITIONS -->
-
- <s2 id=DEFINITIONS>Pop-Up Definition Links
-
- A special class of hyperlink is provided for temporarily displaying
- "elaborative" information. Most frequently, this feature is used to
- display the glossary definition for a key word or phrase.
-
- For example, the following paragraph has three definition links.
-
- <p indent>OSF/Motif graphical user interfaces are constructed using <link
- WIDGETDEF Definition>widgets<\link>. Widgets are organized by form and
- function into <link CLASSESDEF Definition>classes<\link> and <link
- SUBCLASSESDEF Definition>subclasses<\link>.
-
- The use of definition links is not limited to defining key words and
- phrases. For instance, you could use this feature to provide a <link
- hyperlink="Intromgr quick-start" JumpNewView>visual overview<\link> of the
- application.
-
-
-
-

- <!-- GRAPHICS -->
-

- <!-- COMMANDS -->
-
- <s2 id=COMMANDS>Executing Commands
- <idx|Command execution|
- Each of the following icons is a hyperlink assigned to a particular
- system command. If the program in the command is installed on your
- system, clicking the icon will invoke it.
-
- <p gentity=clock ghyperlink="DtHelpExecAlias xclockAlias" glinktype=Execute>This
- icon starts the ``xclock'' program if it is
- installed on your system, and in your PATH.
-
- <p gentity=xload ghyperlink="DtHelpExecAlias xloadAlias" glinktype=Execute>This
- icon starts the ``xload'' program if it is installed on your
- system, and in your PATH.
-
- Command links do not have to be graphics. For example, this link
- executes the <link EXECUTE hyperlink="DtHelpExecAlias dtCalcAlias">CDE
- Calculator<\link> program (if it is installed on your system).
-
- <note>
- The above Execute examples take advantage of Execution Aliases in the
- hyperlinks. When execution alises are defined in the help volume, and
- supported in the hosting client, they execute directly when selected by the
- user.
-
- To learn more general information about supporting execution hyperlinks and
- aliases, refer to the <book|CDE Author's and Programmer's Guide|.

- <!-- COMMUNICATION -->
-
- <s2 id=COMMUNICATION>Two-Way Communication
- <idx|Two way communication|
- A help system that is tightly coupled with an application has more
- potential for presenting relevant, context-sensitive information. The
- architecture of the ...
-
- <otherhead>Help System Controlling the Application
-
- Since CDE Help is intended for use in OSF/Motif-based applications, it takes
- advantage of the !!callback!! mechanism used by all other user interface
- components. Help callbacks notify the application when certain events
- occur within a help window.
-
- Perhaps the most powerful use of help callbacks is the use of
- !!application-defined links!!. These are link types invented by the
- application developer that can have any meaning.
-
-
- For example, a developer may want to create a special type of link to
- play video clips. Each time the user selects one of these links, the
- application is notified so it can do whatever is necessary to play the
- appropriate video.
-
- <xref controlTestId>
-
- <otherhead>Application Controlling the Help System
-
- As a toolkit, all CDE Help facilites are under control of the
- application. All help windows are transient windows of the
- application. The application can control the number of help windows,
- the color schemes used within them and other options provided by the
- CDE Help libraries.
-
-
- <s3 id=controlTestId> Sample Application Defined Links
-
- The following collection of hypertext links demonstrate how the CDE Help
- System can control the hosting application. These links are authored
- as <emph>AppDefined<\emph> links, and require special support in the hosting
- client
-
- <note>
- These example !!application-defined!! links are supported by the ``dthelpdemo''
- program. (If you view this help volume with another application, such as
- dthelpview, the links are ignored.)

- <\list>
-
- <s2 id=MODEL>The CDE Help System Use Model
- <idx|use model|
- <idx|prime directive|
-
- The overriding principle for providing online help is:
-
- <p indent>!!Get the user back on task as quickly and successfully as
- possible.!!
-
- To fulfill this "prime directive," online help must be easily accessible
- within whatever applications the user has chosen to accomplish the task.
-
- The CDE Help System is cast in a supporting roll. That is,
- the help system's job is to function as part of the application with
- the purpose of making the user successful with the rest of the
- application.
-
- <figure nonumber entity=ApplicationWithHelp>
- <\figure>
-
- The idea of keeping the help system tightly coupled with the application
- improves the user's <emph>perceived proximity<\emph>. User are more likely
- to be successful and productive if they feel like devations to get help
- don't take them far from the application.
-
- CDE Help supports two types of <emph> entry
- points<\emph> into online help:
-
- <list bullet>
-
- * <link QUICKHELP>Quick help<\link> presents a focussed node of
- information for a given context.
-
- * <link GENERALHELP>General help<\link> presents navigable information
- that the user can explore.
-
- <\list>
-
-
- <!-- QUICKHELP -->
-
- <s3 id=QUICKHELP>Quick Help
-
- Quick help information is optimized -- by writing style and
- organization -- to get the user back on task with minimal interruption.
-
- <figure entity=QuickHelpModel>
- <\figure>
-
- Quick help has a high level of context sensitivity and contains very
- specific information. By design, the content and presentation of
- quick help information should <emph>not<\emph> encourage the user to
- "explore."
-
- So, what if a quick help entry point doesn't fill the user's need?
- <emph>Progressive disclosure<\emph> sequences are designed to maintain
- a sense of proximity, while exploring an author-constrained path of
- nodes that incrementally provide more information for the given
- context. (This concept is sometimes called "progressive revelation"
- or "progressively-more-help.")
-
- Typical uses of quick help include:
-
- <list bullet>
-
- * Messages (errors, status, etc.).
-
- * Context-sensitive help (invoked with F1 key or Help command button).
-
- * Each step in a constrained progressive disclosure sequence.
-
- * Item help.
-
- * Application copyright and version.
-
- * Simple help on help.
-
- <\list>
-
-
- <!-- GENERALHELP -->
-
- <s3 id=GENERALHELP>General Help
-
- General help information is anything that isn't quick help. Usually,
- general help is intended to be explored (such as this demo).
-
- <figure nonumber entity=GeneralHelpModel>
- <\figure>
-
- Typical uses of general help include:
-
- <list bullet>
-
- * Application overview.
-
- * A follow-up to quick help -- that is, when quick help isn't enough.
-
- * Application tutorials.
-
- * Application training modules.
-
- * Complete help on help (when quick help on help isn't enough).
-
- <\list>
-
-
- <!-- TOOLKIT -->
-
- <s2 id=TOOLKIT>The Toolkit Architecture
-
- Application developers add help components to their
- software just as they add any other window. The CDE Help
- programmer's toolkit defines new widget classes for the various help
- windows. There are many advantages to this toolkit architecture:
-
- <list bullet>
-
- * There's no dependency on a separate help server process -- the
- "help system" is part of the application.
-
- * Response time is dramatically faster.
-
- * Memory usage is significantly less (which increases overall system
- performance).
-
- * User's perceive help to be part of the application, making it seem
- like less of a deviation to ask for help.
-
- * There's no need for an inter-process communication (IPC) mechanism.
- The application interacts with CDE Help components just as it does
- with all other user interface components.
-
- * There's no new programming paradigm -- all CDE Help
- components are accessed using the same object-oriented
- interface used for OSF/Motif (via the Xt Intrinsics and convenience
- functions).
-
- <\list>
-
- Since the CDE Help toolkit is based exclusively on standards (ANSI
- C, Xlib, Xt Intrinsics, and OSF/Motif), it is as portable as any OSF/Motif
- application can be.

- <!-- HELPTAG -->
-
- <s2 id=HELPTAG>Authoring with HelpTag
-
- Authoring for CDE Help is based on the HelpTag markup language and
- accompanying software. HelpTag is based on the SMGL standard (ISO
- 8879).
-
-
- <otherhead>The HelpTag Markup Language
-
- Online help is written in ordinary text files. You use special codes, or tags to
- markup elements within the information. The tags form a markup language called
- CDE HelpTag.
-
- The CDE HelpTag markup language defines a hierarchy of elements that define
- high-level elements such as chapters, sections, and subsections, and low-level
- elements such as paragraphs, lists, and emphasized words.
-
- To learn more general information about authoring with CDE HelpTag, refer to
- the <book|CDE Author's and Programmer's Guide|.
-
-
- <otherhead>The HelpTag Software
-
- The HelpTag software is responsible for converting the author's files
- into the run-time help files that are shipped with the application.
- The software is invoked with a command like this:
-
- <ex>dthelptag %%basename%%.htg<\ex>
