                                                 Windowing and Mouse Techniques




                  You work with the DECwindows 4125 Emulator (DW4125 Emulator)
                  using the same mouse and windowing techniques as other
                  DECwindows applications.

                  This chapter summarizes some basic techniques you will use to
                  operate the emulator.

                   _ Using the Mouse

                   _ Starting a Session

                   _ Using Windows

                   _ Selecting Windows

                   _ Changing the Size of Windows

                   _ Shrinking Windows

                   _ Expanding Icons to Windows

                   _ Moving Windows

                   _ Stacking Overlapping Windows

                   _ Choosing Items from Pull-Down Menus

                   _ Supplying Information in Dialog Boxes

                   _ Getting Help




                                            Windowing and Mouse Techniques  1-1

 











                   _ Putting a Session on Hold

                   _ Ending a Session

               Using the Mouse

                  You use the mouse to communicate with your Tektronix 4125
                  application, to choose commands from a menu, to expand and
                  shrink windows, and to rearrange windows on your screen.
                  The mouse has three buttons. Unless you specify otherwise,
                  MB1 (for "mouse button 1") is on the left, MB2 is in the
                  middle, and MB3 is on the right. This button arrangement
                  naturally suits right-handed users. If you are left-handed,
                  you can easily rearrange this configuration by changing the
                  button arrangement setting in the Session Manager's Customize
                  Pointer dialog box.

                  You can do all your work with the mouse by mastering the
                  following techniques:

                   _ Point: Using the mouse, move the cursor to where you want

                     the next action to occur.

                   _ Click: Quickly press and release MB1.

                   _ Press: Point to the menu name, stepping arrow, or wherever

                     you want the action to occur and without moving the mouse,
                     press and hold MB1 or MB2. If you are pointing at a menu
                     name, pressing MB1 pulls down a menu and keeps it down
                     until you release MB1.

                   _ Drag: Press and hold MB1, move the pointer, and release

                     MB1. If you are displaying a pull-down menu, cancel the
                     drag by moving the pointer outside the menu and releasing
                     MB1.

                   _ Double click: Point to the object and click MB1 twice in

                     quick succession.

                   _ Shift click: Point to the object. Press and hold the Shift

                     key and click MB1. Release the Shift key.

               Starting a Session

                  If the system startup procedure has been successful, your
                  screen looks like this:

























                  The Start Session dialog box prompts you for your user name
                  and password. A dialog box is displayed whenever the system
                  needs information from you.

                  You type your user name and password in the appropriate
                  text entry fields. A text insertion cursor is visible in
                  each field. The text cursor in the Username field blinks to
                  indicate this field has input focus. When a text field or
                  window has input focus, you see your keystrokes echoed there.
                  The text cursor in the Password field is dimmed, indicating
                  that you cannot currently enter text in it.

                  To start a session:

                   1 Type your user name.

                     If you make a typing mistake, press the Delete key (<_  )

                     to erase the character to the left of the text cursor.
                     To insert a character in the middle of text you already
                     typed, point where you want the text inserted and click
                     MB1. Or use the right and left arrow keys to move the text
                     cursor right or left. The new characters you type push
                     existing ones to the right.

                   2 Select the Password field by pointing to the Password
                     field and clicking MB1 or by pressing <Tab> or <Return>.
                     The blinking text cursor indicates that the Password field
                     has input focus.

                   3 Type your password.

                     To preserve the secrecy of your password, the characters
                     you type are not displayed on the screen.

                     If you make a typing mistake, click on the Clear button.
                     This erases all text in both the Username and Password
                     fields so that you can retype your information correctly.
                     Clicking on buttons in dialog boxes enables you to specify
                     what to do with the information.

                   4 Click on the OK button or press <Return>.

                  The double outline around the OK button in the Start Session
                  dialog box indicates it is the default option. Default
                  options are those you choose most frequently. You can use
                  a shortcut to choose default options: Whenever you see a
                  button with a double outline, pressing <Return> achieves the
                  same results, in most cases, as clicking on that button.

                  If you provide incorrect information, or make a typing
                  mistake and do not correct it, you cannot start a session.
                  Instead, a Problem Report dialog box is displayed as a
                  warning that some information is incorrect.

                  Click on the Acknowledged button or press <Return> to try
                  again.

                  If the information you supplied is correct, your session
                  begins.

               Using Windows

                  A window is an area on your workstation screen that
                  represents all or part of an application. For example, the
                  DW4125 Emulator graphics window is one of several windows
                  available in the DECwindows system.

























                   _ The title bar at the top identifies the DW4125 window.

                   _ The menu bar directly beneath the title bar enables you to

                     access the DW4125 Emulator.

                   _ The work area in the remaining space displays the DW4125

                     Emulator text and graphics.

               Selecting Windows

                  When you have more than one window open, you indicate which
                  window you want to work with by selecting it. The window
                  moves to the front of the "stack" of overlapping windows. Its
                  title bar is highlighted to indicate it has input focus. For
                  many applications, any keystrokes you type are displayed in
                  this window. When you select another window, the new window
                  is given input focus. Only one window can have input focus at
                  a time.

                  To select a window:

                   1 Point to a location in the title bar.

                   2 Click MB1.

               Changing the Size of Windows

                  You may want very large windows so you can display more
                  information or you may want to work with small windows, such
                  as when several applications are running simultaneously.
                  You can change the size of your windows by using the resize
                  button.

                  To change the size of a window:

                   1 Point to the window's resize button.

                   2 Press and hold MB1.

                     The pointer changes into a small resize cursor.

                   3 Drag the resize cursor until the window is the size you
                     want.

                     To make the window larger, drag the resize cursor beyond
                     the window border. To make the window smaller, drag the
                     resize cursor beyond the window border and then back in.
                     The outline stops moving when the window is the smallest
                     size it can become.

                   4 Release MB1.

                  You can change the size of a window in one dimension (height
                  or width) or in both dimensions simultaneously. To change
                  the size in one dimension, drag the resize cursor across one
                  border of the window. As long as you cross only one border,
                  the outline that follows the resize cursor changes in only
                  one dimension. If after crossing one border you cross an
                  adjacent border, you see an outline that can change in both
                  dimensions.

               1-6  Windowing and Mouse Techniques

 











                  If you drag the resize cursor through one border and then
                  through the opposite border, the first border you crossed
                  reverts to its original location, and the other border
                  becomes an outline that follows the resize cursor.

                  To cancel a window-resizing operation in progress, click
                  another mouse button before releasing MB1. The outline
                  disappears, and the window retains its original size.

               Shrinking Windows

                  You can shrink a window to an icon if you want to free some
                  space on your screen to run other applications without
                  exiting from an application. When you shrink a window to
                  an icon, the application it represents continues to run in
                  memory and remains accessible. Any processes continue to
                  execute while the application is stored as an icon.

                  When a window is on the screen, its icon is dimmed. The icon
                  appears bold when the window is stored in the Icon Box. If
                  the Icon Box contains more icons than can be displayed at
                  once, scroll bars are displayed. You use scroll bars to view
                  the icons that do not fit in a single window.

                  To shrink the DW4125 Graphics window to an icon:

                   1 Point to the window's shrink-to-icon button.

                   2 Click MB1.

                     The window disappears and its icon in the Icon Box appears
                     bold.

                  You cannot shrink the Icon Box to an icon.

                  As you stop applications, your Icon Box develops gaps where
                  icons used to appear. You can rearrange the icons in the Icon
                  Box in two ways:

                   _ By moving the icons. To move an icon, drag it to a new

                     location.

                   _ By clicking on the Icon Box's shrink-to-icon button.

                     Clicking on this button in an application window shrinks
                     the window to an icon. Clicking on this button in the Icon
                     Box, however, eliminates the gaps between icons that may
                     develop when you stop applications.

               Expanding Icons to Windows

                  When you expand an application icon, you restore a window
                  for that application. If you have more than one window open
                  and expand an icon to a window, that new window is placed at
                  the front of the stack of overlapping windows. If the window
                  accepts text entry, it is also given input focus.

                  To expand an icon to a window:

                   1 Point to the icon in the Icon Box.

                   2 Click MB1.

               Moving Windows

                  If one window partially obscures another, you might want to
                  arrange the windows so that each is completely visible. To
                  move a window, drag it by its title bar.

                  To move a window:

                   1 Position the pointer anywhere in the window's title bar
                     (except in the shrink-to-icon, push-to-back, or resize
                     buttons).

                   2 Press and hold MB1.

                     An outline of the window is displayed.

                   3 Drag the window to the new location.

                   4 Release MB1.

                     If the window was partially obscured by other windows, it
                     moves to the front of the stack of windows and is given
                     input focus.

                  To cancel a window-moving operation in progress, click
                  another mouse button before releasing MB1. The outline
                  disappears and the window is not moved.

               Stacking Overlapping Windows

                  When you are working with stacked windows and select a
                  window, it moves to the front of the stack and is given input
                  focus. But if a larger window completely obscures a smaller
                  window, you cannot select that small window without moving
                  the larger window out of the way. If you use the title bar to
                  move the larger window, you disrupt your window arrangement.

               1-8  Windowing and Mouse Techniques

 











                  By clicking on the visible window's push-to-back button,
                  you can push that window to the back of the stack and expose
                  the window underneath. Without moving the windows to another
                  location on the screen, you can push one window out of the
                  way or retrieve another to work with.

                  To push the front window to the back of a stack of overlap-
                  ping windows:

                   1 Point to the front window's push-to-back button.

                   2 Click MB1.

                  If you try this repeatedly with three or more windows, you
                  see that the windows cycle through the stacking order, moving
                  up one position in the stack each time a window is moved to
                  the back of the stack.

                  Locking Overlapping Windows in the Stacking Order

                  When you are working with overlapping windows and select one
                  window, it moves to the front of the stack and is given input
                  focus. You can, however, prevent a partially obscured window
                  from moving to the front of the stack when you select it by
                  arranging the windows to display only what you need to see
                  and then securing them in place.

                  To lock overlapping windows in the stacking order:

                   1 Point to a window's push-to-back button.

                   2 Shift click on the button.

                     That window is pushed to the back of the stack.

                  The lower right-hand corner of the push-to-back button is
                  filled to indicate that the window is fixed in the stacking
                  order. Although the window is given input focus when you
                  select it, it does not pop to the front of the stack.

                  You can still push to the back or bring to the front any
                  window that you have fixed in the stacking order to see it
                  unobscured.

                  To move overlapping windows in the stacking order:

                   _ Click on a window's filled push-to-back button to move

                     that window to the opposite position in the stack, but not
                     give the window input focus.

                   _ Click on a filled push-to-back button to push an

                     unobscured window to the back of the stack.

                   _ Click on a filled push-to-back button to move a partially

                     obscured window to the front of the stack.

                  Releasing Windows Locked in the Stacking Order

                  To release a window locked in the stacking order, shift click
                  on the window's push-to-back button. If the window was at
                  the back of the stack, it moves to the front; if the window
                  was at the front, it is pushed to the back. The push-to-back
                  button is no longer filled.

               Choosing Items from Pull-Down Menus

                  The names of menus available in an application are displayed
                  on the menu bar. When you press MB1 on a menu name, the
                  menu's contents are displayed or pulled down.






























                  You choose commands or menu items from pull-down menus. An
                  ellipsis ( . . . ) following a menu item indicates that a
                  dialog box is displayed if you choose that menu item.

                  To choose an item from a pull-down menu:

                   1 On the menu bar, point to the name of the menu you want to
                     display.

                   2 Press and hold MB1.

                     This highlights the menu name and pulls down a menu.

                   3 While holding MB1, drag to the menu item you want.

                   4 Release MB1.

                  If you change your mind while looking at a pull-down menu,
                  drag outside the menu and release MB1. The menu disappears
                  and no action is taken.

                  Some applications offer rectangular push buttons to duplicate
                  frequently used commands that are also available as
                  menu items. Push buttons are usually found underneath an
                  application's work area. To execute these commands quickly,
                  click MB1 on the push button.

               Supplying Information in Dialog Boxes

                  A dialog box is displayed whenever additional information
                  is needed to carry out a task. Sometimes you need to type
                  text; other times, you need only click on a button to change
                  a setting. Some dialog boxes display settings you chose
                  earlier.

                  Dialog boxes offer various ways to supply information to an
                  application:

                   _ By typing text in a text entry field. The blinking text

                     cursor shows you where the text you type is displayed.
                     What you type is displayed to the left of the text cursor.

                   _ By clicking on option buttons or square toggle buttons.

                     Option buttons let you select one option from many. Toggle
                     buttons let you turn a setting on or off.

                   _ By dragging the slider in a scale. Dialog boxes often

                     contain a scale and slider when you need to supply a
                     numeric value. The arrow in the slider points to the
                     current value.

                   _ By selecting choices, for example, file names, from a list

                     box. A list box contains a list of items you can choose.
                     Scroll bars are displayed if the choices do not fit in the
                     list box.

                   _ By clicking on push buttons. Push buttons, such as OK,

                     Cancel, or Filter, tell the DECwindows system what to do
                     with the information you supplied in the dialog box.

                     In a dialog box, the OK button is usually the default
                     option. You can press <Return> to achieve the same result

               Getting Help

                  The DECwindows Help system provides brief information about
                  screen objects, concepts, and tasks. You get help on specific
                  screen objects, for example, scroll bars and menu items, by
                  pressing the Help key and MB1.

                  Help is designed to let you request general information and
                  quickly narrow the focus of your inquiry. In Help, you can:

                   _ Navigate quickly through help topics. Help keeps track

                     of the path you used to get to a particular topic, which
                     makes it easy for you to retrace your steps and follow a
                     different path.

                   _ Search Help for a keyword or topic supplied by the

                     application.

                  Invoking Help

                  To get help, choose Overview from the Help menu.

                  A help window opens with the Overview topic displayed,
                  including a list of additional topics that explain how to
                  do common tasks.

                   _ The Help topic describes the task or object about which

                     you requested help. Scroll bars are displayed if the text
                     does not fit in one frame.

                   _ The Additional topics list contains related topics that

                     you can select to display more information. You select
                     these topics by pointing to them and double clicking MB1.

                   _ The help buttons, Go Back and Exit, let you display the

                     previous help frame or exit from Help.

                  To get help on screen objects such as menu names, scroll
                  bars, and dialog boxes, point to the screen object, and press
                  and hold the Help key on your keyboard while you click MB1.
                  Note that help on objects is not available in all DECwindows
                  applications.

                  To get help on a menu item, press the Help key while you
                  press and hold MB1 on the menu item, then release MB1. A
                  help window opens, displaying information on the object you
                  specified.

                  You can display product information about your application,
                  such as the software version number, by choosing About from
                  the application's Help menu. In some applications, the Help
                  menu also contains a Glossary menu item, which you can use to
                  look up terms specific to your application.

                  For more information about using Help, choose Help from the
                  Help menu in each application's help window.

                  Navigating in Help

                  When you select a topic from the Additional topics list in
                  the Overview window, you start down a path that is limited
                  only by your own curiosity. You can follow a path of topics
                  by continuing to select additional topics, retrace your
                  steps and branch off to a different topic, or return to the
                  Overview frame and start down another path.

                  To display an additional topic:

                   1 Select the item from the list of additional topics.

                   2 Choose Go To from the View menu.

                  You can also double click on the topic you want. Double
                  clicking on a topic is a shortcut for selecting the topic
                  and choosing Go To.

                  Help displays the selected topic. You can continue to select
                  other topics from the Additional topics list or display the
                  topic you last saw by clicking on the Go Back button.

                  If you want to display the current topic and a new topic
                  simultaneously:

                   1 Select another topic from the list of additional topics.

                   2 Choose Visit from the View menu.

                  Instead of replacing the current help topic with the new
                  topic, another help window opens that displays information
                  about the new topic. You can then explore other topics from
                  the new help window and keep the current topic open for
                  reference.

                  To see the path you followed to get to your current topic:

                   1 Choose History... from Help's Search menu.

                     Help displays a dialog box that lists the topics you have
                     already seen.

                   2 Double click on a topic to replace the current topic
                     or select a topic and click on the Visit button to open
                     another help window without replacing the current topic.

                  When you finish looking at a topic and want to close the help
                  window, click on the Exit button. To return to the Overview
                  frame, choose Go To Overview from the View menu in any help
                  window.

                  Exiting from Help

                  To exit from Help, click on the Exit button. If you have
                  multiple help windows open, you must close each one.

               Putting a Session on Hold

                  You can put your current session on hold without ending the
                  session. When you put your session on hold, your screen is
                  cleared, but your session is maintained. Any applications you
                  started continue to run.

                  To put your current session on hold, choose Pause from the
                  Session Manager's Session menu. Your screen is cleared and
                  the Continue Session dialog box is displayed.

                  To continue your session, type your password and press
                  <Return>. Once the system verifies your password, your
                  session resumes. If the Continue Session dialog box remains
                  on your screen, you probably made a typing mistake. Click on
                  the Clear button and type your password again.

               Ending a Session

                  You can end a session at any time. When you end a session all
                  applications stop running, the screen clears, and the Start
                  Session dialog box is displayed.

                  To end your DECwindows session:

                   1 Choose Quit from the Session Manager's Session menu.

                     If the Session Manager displays a dialog box asking you to
                     confirm that you want to end the session:

                   2 Click on OK or press <Return>.

                                                 Installing the DW4125 Emulator




                  This chapter explains how to prepare your VMS or ULTRIX
                  system for installation and contains the installation
                  procedures for the following software:

                   _ DECwindows 4125 Emulator for VMS, Version 1.0

                   _ DECwindows 4125 Emulator for ULTRIX/VAX, Version 1.0

                   _ DECwindows 4125 Emulator for ULTRIX/RISC, Version 1.0

                  This chapter discusses the following topics related to
                  installing the DW4125 Emulator:

                   _ Preparing to Install the Software on a VMS System

                   _ Installing the Software on a VMS System

                   _ Preparing to Install the Software on an ULTRIX System

                   _ Installing the Software on an ULTRIX System

                   _ Updating the Applications Menu

               Preparing to Install the Software on a VMS System

                  The VMS operating system comes with a variety of support
                  options, or classes. Classes include features such as
                  networking. The DW4125 Emulator requires the same classes
                  as required for the DECwindows environment. For a complete
                  list of the required classes for the DECwindows 4125 Emulator
                  for VMS, see the Software Support Addendum (SSA), which comes
                  with the Software Product Description (SPD).

                  Before you install the emulator software:

                   _ Your system must be running DECwindows on VMS Version 5.2

                     or 5.3.

                   _ You must register and load your license for DECwindows

                     4125 Emulator for VMS in order to run the Installation
                     Verification Procedure (IVP) and use the software.

                     To register under VMS, first log in to the system
                     manager's account, SYSTEM. Perform the registration in
                     either of the following ways:

                      _ Invoke the SYS$UPDATE:VMSLICENSE.COM procedure. When

                        it prompts you for information, respond with data from
                        your License PAK.

                          $ @SYS$UPDATE:VMSLICENSE.COM

                      _ At the DCL prompt, enter the LICENSE REGISTER command

                        with the appropriate qualifiers that correspond to
                        License PAK information.

                          $ LICENSE REGISTER

                     If you plan to use the DW4125 Emulator on more than one
                     node in a VAXcluster system, you need to load the license
                     on the other nodes after you complete the installation.

                     For complete information on using the License Management
                     Facility (LMF), see the VMS License Management Utility
                     Manual.

                   _ Make sure you have a backup copy of your system disk.

                     See the section on the Backup Utility in the VMS System
                     Management Subkit for detailed information.

                   _ Check your disk space. The emulator requires 4000 blocks

                     of free disk space.

                     To determine the number of free blocks on your system,
                     enter:

                       $ SHOW DEVICE SYS$SYSDEVICE

                     If you do not have enough disk space, delete or tailor
                     files that you do not need (see your VMS installation and
                     operations guide for further information).

               2-2  Installing the DW4125 Emulator

 











               Installing the Software on a VMS System

                  You use the VMSINSTAL installation procedure to install the
                  emulator. The installation takes approximately 10 minutes.

                  To display or print release notes, specify OPTIONS N on the
                  VMSINSTAL command line:

                    $ @SYS$UPDATE:VMSINSTAL DW4125010 device-id OPTIONS N

                  To install the emulator:

                   1 Locate the DECwindows 4125 Emulator for VMS Version 1.0
                     Software Media Kit.

                   2 To start the VMSINSTAL procedure, enter:

                       $ @SYS$UPDATE:VMSINSTAL DW4125010 device-id OPTIONS N

                     Press <Return>.

                     @SYS$UPDATE:VMSINSTAL

                                 specifies the installation procedure.

                     DW4125010   specifies Version 1.0 of the emulator
                                 software.

                     device-id   specifies the device on which you plan to
                                 mount the media.

                     OPTIONS N   selects the release notes option.

                     For example, to install the emulator from a magnetic tape,
                     enter:

                       $ @SYS$UPDATE:VMSINSTAL DW4125010 MTA0: OPTIONS N

                     Once you press <Return> the following message appears:

                       VAX/VMS Software Product Installation Procedure V5.X

                       It is dd-mmm-yyyy at hh:mm
                       Enter a question mark (?) at any time for help.

                   3 Confirm system backup:

                       * Are you satisfied with the backup of your
                       system disk [YES]?

                                            Installing the DW4125 Emulator  2-3

 











                     If you have completed the system backup, press <Return>
                     . Otherwise, enter NO to exit from VMSINSTAL and refer
                     to your VMS installation and operations guide for system
                     backup instructions.

                  Note To exit the installation procedure at any time, press
                     <Ctrl/Y> . The installation procedure deletes all files it
                     has created up to that point and exits.

                   4 If you choose to continue, you are asked to mount the
                     media:

                       Please mount the first volume of the set on DDCU: YES
                       * Are you ready? <Return>

                     Insert the media into the disk drive, enter YES, and press
                     <Return>.

                     VMSINSTAL displays information similar to the following:

                       The following products will be processed:

                          DW4125 V1.0

                       %VMS-I-RESTORE, Restoring product saveset A  . . .

                   5 If you specified OPTIONS N in the command line, VMSINSTAL
                     displays the following:

                       Release notes included with this kit are always copied
                       to SYS$HELP.

                       Additional Release Notes Options:

                       1. Display release notes
                       2. Print release notes
                       3. Both 1 and 2
                       4. None of the above

                       * Select option [2]:

                     If you select option 1, VMSINSTAL displays the release
                     notes immediately on your screen. You can terminate the
                     display anytime by pressing <Ctrl/C> .

                     If you select option 2, VMSINSTAL prompts you for the name
                     of the print queue:

                       * Queue name [SYS$PRINT]:

                     You can enter <Return> to send the file to the default
                     output print device or enter another queue name.

                     Select option 4 if you reviewed the release notes and are
                     restarting the installation.

                     Next, VMSINSTAL displays the following question:

                       * Do you want to continue the installation [N]?

                     To continue the installation, enter YES. Otherwise, press
                     <Return> . In either case, the release notes are copied to
                     a file in the SYS$HELP directory SYS$HELP:DW4125010.RELEASE_
                     NOTES.

                       %VMSINSTAL-I-RELMOVED, the product's release notes have
                       been successfully moved to SYS$HELP.

                     To print the release notes after installation of the
                     product, enter the following command:

                       $ PRINT/QUEUE=queue SYS$HELP:DW4125010.RELEASE_NOTES

                   6 If you are reinstalling the software, VMSINSTAL asks if
                     you wish to purge files from an older version:

                       * Do you want to purge files replaced by this
                       installation [YES]?

                   7 VMSINSTAL asks if you wish to run the Installation
                     Verification Procedure (IVP). The IVP for the DW4125
                     Emulator for VMS checks to be sure the installation is

                  If you are running the emulator on a cluster node other than
                  the node on which the software was installed, you may want to
                  run the IVP on your node to verify the installation.

               Preparing to Install the Software on an ULTRIX System

                  Before starting the installation procedure on an ULTRIX/RISC
                  or ULTRIX/VAX system:

                   _ Make sure that your system is running ULTRIX Worksystem

                     Software Version 2.2 or 4.0.

                   _ Make a backup copy of your system disk. See the ULTRIX-

                     32 Guide to System Backup and Restore for detailed
                     information.

                   _ Locate the DECwindows 4125 Emulator Version 1.0 Software

                     Media Kit for your operating system.

                   _ Determine the name of the device on which you will mount

                     the media. On most workstations, the location of the TK50
                     tape drive is /dev/rmt0h.

                   _ Load the tape into your drive.

                   _ Log in to the root account. You must be in superuser mode

                     to install the emulator.

                   _ Check your /usr disk space using the df command. The

                     disk space required for installation is 1400 kbytes. The
                     permanent disk space required for use is 1400 kbytes.

                   _ Delete any installation of the same kit with the following

                     command:

                       # /etc/setld -d DWREM100

                                                      Using the DW4125 Emulator




                  This chapter describes how to create emulator windows and use
                  the Commands menu items on a VMS or ULTRIX system. It also
                  provides information on DW4125 Emulator functionality as it
                  compares to a Tektronix 4125 terminal. The chapter discusses
                  the following topics:

                   _ Creating Emulator Windows

                   _ Preparing to Use the Emulator

                   _ Using the Emulator

                   _ Exiting from the Emulator

                   _ Managing Error Messages

                  This chapter does not provide instructions on Tektronix 4125
                  terminal functions. See your Tektronix documentation for
                  specific functions.

               Creating Emulator Windows

                  After installing the DECwindows 4125 Emulator software and,
                  optionally, adding the DW4125 Emulator menu item to the
                  Application menu, you are ready to create emulator windows.
                  (For directions for adding the menu item to the Applications
                  menu, see the DECwindows User's Guide.)

                  You can start the DW4125 emulator by:

                   _ Using the DCL or shell command interface

                   _ Using the Applications menu (after you have added the

                     DW4125 Emulator menu item )

                                                 Using the DW4125 Emulator  3-1

 











                   _ Customizing autostart (after you have added the DW4125

                     Emulator menu item)

                  On a VMS system, to create emulator windows using the DCL
                  command interface, enter:

                    $ RUN SYS$SYSTEM:DW4125

                  On an ULTRIX/VAX or ULTRIX/RISC system, to create an emulator
                  window using the shell command interface, enter:

                    %dw4125

                  In either a VMS or an ULTRIX environment, to create an
                  emulator window using the Applications menu do the following:

                   1 On the menu bar, point to the Applications menu.

                   2 Press and hold MB1.

                   3 While holding MB1, drag to the DW4125 menu item.

                   4 Release MB1.

                  An emulator window with the Digital copyright is displayed
                  along with an emulator dialog window.





















               3-2  Using the DW4125 Emulator

 





































                  Give the emulator graphics window input focus by pointing to
                  it and clicking MB1. The DW4125 Graphics window is displayed.

                  The dialog area of the DW4125 Emulator is a separate
                  DECwindows standard window, unlike the Tektronix 4125
                  terminal dialog area that overlays the graphics area.
                  Therefore, you can move, resize, and iconify the DW4125
                  Dialog Area window. The Dialog Area window can be positioned
                  anywhere on the screen, including partially off the screen.
                  Using the mouse to resize and relocate the Dialog Area window
                  is similar to using dialog area escape sequences. The DW4125
                  Emulator saves the size and uses it to create future dialog
                  windows. The application or user can specify up to 64 dialog
                  windows.

               Preparing to Use the Emulator

                  This section contains information on setting up special
                  application modes, toggling between color maps, and providing
                  comparable Tektronix 4125 functionality with the DW4125
                  Emulator.

                  Setting Up Special Application Modes

                  Default settings on the DW4125 Emulator are the same as the
                  factory defaults for a Tektronix 4125 terminal. In general,
                  application software sets up the DW4125 Emulator in the
                  particular mode that it requires. However, if you use an
                  application that requires that you set up a particular 4125
                  initialization or mode, you will need to do either of the
                  following to ensure that the mode is correct. (The DW4125
                  Emulator does not have a SAVE feature.)

                   _ Create a program to generate the appropriate escape

                     sequences and run it in the DW4125 dialog area before
                     running the application

                   _ Store the escape sequences in a file and display the file

                     in the DW4125 dialog area before running the application

                  Toggling Between Color Maps

                  The DW4125 Emulator uses the default Tektronix 4125 terminal
                  color model. During a DW4125 graphics session, other colors
                  on the workstation may change. You can toggle between the
                  default DECwindows color map and the emulator color map by
                  pressing <Ctrl/Shift/F10> in an emulator window.

                  Providing Thumbwheel Functionality

                  Use the arrow keys on the Digital LK201 and LK401 keyboards
                  to provide the same functionality as the thumbwheel on the
                  Tektronix 4125 keyboard. The graphics cursor moves in the
                  direction indicated by the arrow. You can vary the speed of
                  the graphics cursor as follows:

                   _ <Shift/arrow> - faster speed

                   _ <arrow> - medium speed

                   _ <Ctrl/arrow> - slower speed

                  On the Tektronix 4125 terminal, holding down the Shift key
                  during thumbwheel action causes slower motion.

                  Providing Tablet Functionality

                  Use the mouse to provide tablet input to Tektronix 4125
                  applications. For most applications that request tablet
                  input, the mouse can be used instead of the stylus or puck.

                  Managing the Graphics Area

                  To manage the graphics area of the DW4125 Emulator, consider
                  the following:

                   _ When you resize the graphics area, the emulator erases

                     previous designs. However, if you defined views with the
                     application, you can redraw the graphic designs with Renew
                     Current and Renew All from the Commands menu. To ensure
                     against the loss of previous designs, resize the DW4125
                     Graphics window before starting the application.

                   _ When an application sends a graphics design to the DW4125

                     Emulator, the emulator scales (never clips) the design to
                     fit the usable area of the graphics window. The usable
                     graphics area is the largest square that fits in the
                     available window space.

                   _ If text in the graphics area is too small or overlaps,

                     increase the size of the DW4125 Graphics window and rerun
                     the application.

               Using the Emulator

                  Once you have created the emulator windows, you can run your
                  Tektronix 4125 application and use the graphics window's
                  Commands menu.

                  To start your application in the DW4125 Graphics window, do
                  the following:

                   1 Give input focus to the DW4125 Dialog Area window

                   2 Enter the system command to start the application

                  and execute all 4125 setup commands here.

                  As you enter commands in the Setup window:

                   _ The leading escape character in the escape sequence format

                     is not required.

                   _ The commands are not case-sensitive.

                   _ Enter floating point numbers normally (10.5).

                   _ Enclose arrays in angle brackets (< >).

                  Entering HELP command-name in the DW4125 Setup window
                  provides a summary of the named command. You can enter the
                  command name, a recognized abbreviation of the command name,
                  or the two-character escape sequence. For example, you can
                  enter either, HELP DAVIS or HELP LV.

                    help davis
                    LV  davisibility
                               visibility     YES or NO        (no,yes)

                               visibility     YES or NO        (no,yes)

                  Entering STATUS in the Setup window provides a report on the
                  following:

                   _ General terminal status

                   _ Status of related groups of parameters

                   _ Settings of individual terminal parameters

                  To see all the status entries, enlarge the Setup window
                  before entering the command.

                  Entering STATUS option in the Setup window provides a report
                  on the option requested. Information is available for the
                  following status command options:

                   _ report/input

                   _ general

                   _ optional (optional communications)

                   _ dialog (dialog area)

                  For example, the emulator provides a report of the following
                  parameters when you enter STATUS DIALOG in the Setup window:

                    status dialog
                                                  Dialog

                  You can choose the following Viewing Keys options:

                   _ Zoom (both)-Clicking on this option turns on the zoom

                     option. A rectangle is displayed and positioned around the
                     viewpoint. Use the up and right arrow keys to increase the
                     height and width of the window (zoom out). Use the down
                     and left arrow keys to decrease the height and width of
                     the windows (zoom in). In both cases, the image maintains
                     its aspect ratio, or current height and width. To change
                     the aspect ratio, use the Zoom (each) option.

               Exiting from the Emulator

                  Choose the Quit menu item to exit from the DW4125 Emulator
                  and to close all Emulator windows.

               Managing Error Messages

                  When the emulator detects an error in either a setup command
                  or an escape sequence, it displays an error message that
                  corresponds to the error message displayed on the Tektronix
                  4125 terminal. If you request a Tektronix 4125 feature
                  or setup command that the emulator does not support, the
                  emulator issues an error message indicating that the feature
                  is not supported.

                  If error messages on the screen are distracting and you
                  determine that the level of the error is harmless to the
                  Tektronix 4125 application, you can stop the output of
                  these messages to the screen with either the KT (SET-ERROR-
                  THRESHOLD) escape sequence or its equivalent setup command
                  ERRORLEVEL n. The n indicates the severity level of the
                  errors to be silenced. For example, to silence all errors,
                  enter either of the following in the DW4125 Setup window:

                    errorlevel 4

                    KT 4

                  For more information on error messages and codes, see the
