When DECterm sends a ReGIS locator report in response to the R(P(I)) command, or in multiple input mode and the locator position is outside the addressable area, DECterm sends a locator report with the coordinates omitted. For example, press the A key to generate the report:
A[]<CR>, where <CR> is a carriage return (ASCII code 13). |
This section contains release notes pertaining to the DECwindows CD Player application.
The DECwindows CD Player (DECW$CDPLAYER) application in the DECW$EXAMPLES directory requires PHY_IO and DIAGNOSE privileges to operate the compact-disc player hardware. Either your process or the image must have these privileges.
V1.3
The Compress Drawer operation in DECwindows Mail has been updated and no longer results in an access violation.
V1.2--6
With the removal of the support for Display PostScript from the current version of DECwindows Motif, DECWmail no longer supports the display of messages that are exclusively PostScript code. In previous versions, DECWmail sensed the presence of a mail message containing PostScript and used Display PostScript to display the message.
Currently, when DECWmail detects a messages that is exclusively PostScript code, it displays the following error message:
[This PostScript® message cannot currently be displayed.] |
As a workaround, use the Extract option in the File menu, (deselect the "Include Header Information" button in the Extract dialog box), and print the extracted file.
V1.2--4
In DECwindows Mail, if the user selects one or more messages in the directory window using MB1 and then clicks on MB2 in another window (such as a DECterm window), the entire contents of the selected messages is pasted into the other window. The selected messages are highlighted in the directory window, however the text of the selected and pasted message is not highlighted in the Read window.
V1.2--3
Enhancements in the DECwindows Mail application to comply more closely with OSF/Motif style conventions cause some changes with application responses to keyboard actions. Note the following changes.
If you use the Tab key to advance through text entry boxes in the Create/Send window, the current field is no longer highlighted. To select a field, use one of the standard Motif actions, such as double or triple clicking MB1, or use the Shift+Alt -> key sequence.
In several dialog boxes, press either the Select key or the space bar to activate a pushbutton through the keyboard. Note that the Return key and the Enter key are bound to other widgets in the dialog box. Alternatively, you can continue to click MB1 to activate a pushbutton.
V1.2
If you use the color customizer sample program provided in the directory DECW$EXAMPLES to control DECwindows Mail colors, the DECwindows Mail color customization dialog boxes used to modify those colors may not reflect the correct current color values. This is normal behavior; use the color customizer instead of the DECwindows Mail color customization dialog boxes to change these values. Alternatively, exit from the color customizer and restart DECwindows Mail. See HP DECwindows Motif for HP OpenVMS Alpha New Features for more information about the color customizer.
This section contains release notes pertaining to the Notepad application.
V1.2--3
The Notepad application is linked with the OSF/Motif Release 1.1.3 Toolkit. Notepad is not modified to link with the OSF/Motif Release 1.2.3 Toolkit, which is provided with the HP DECwindows Motif for HP OpenVMS Alpha Version 1.3 product. The following restrictions apply:
This section contains release notes pertaining to the Paint application.
If your workstation does not have sufficient colormap entries to view or edit a color image, Paint creates a private colormap. When this happens, the Paint image retains its colors, but the colors on the rest of the workstation are modified. To restore the colors to their original values, give another window input focus by clicking on it.
On GPX systems, Paint might appear slow even when performing basic operations such as drawing a brush stroke. This is because the pixmap is being swapped into the pixmap memory in order to paint the object. If Paint performance is slow, click on the Pencil tool and draw a point in the image area. This should improve performance following the initial Pencil click.
When editing images (especially color images), you can resize the image area using the Picture Size... entry from the Options menu. Resize to the least possible image area to significantly reduce the amount of required pixmap memory.
This section contains release notes pertaining to the Session Manager application.
V1.2
When specifying a list of users who can access the X server in the Authorized Users dialog box, place the node name within quotation marks if the name contains any of the following:
Session Manager automatically adds quotation marks to the node name if they are needed, unless the node name begins with a double quotation mark. If the node name begins with a double quotation mark, Session Manager assumes that the user has already quoted the node name and does not change it.
Within a quoted string, a double quotation mark should be replaced by two double quotation marks (""). For example, the quoted string "DEC:.zko."my node"" should be changed to the following:
("DEC:.zko.""my node""").

V1.2
If you are using the color customizer example program provided in the directory DECW$EXAMPLES to control Session Manager colors, the Session Manager color customization dialog boxes used to modify those colors may not reflect the correct current color values. This is normal behavior; use the color customizer instead of the Session Manager color customization dialog boxes to change these values. Alternatively, exit the color customizer and restart your session. See the HP DECwindows Motif for HP OpenVMS Alpha New Features manual for more information about the color customizer.
Applications created by FileView and Session Manager are detached processes.
The implication is that during application startup,
SYS$MANAGER:SYLOGIN.COM and SYS$LOGIN:LOGIN.COM command procedures are
executed. Any command executed by these command procedures which reads
from SYS$INPUT reads data intended to be used by FileView or Session
Manager for the application startup. This prevents the application from
starting. Examples of such commands are INQUIRE, READ/PROMPT, and SET
TERMINAL/INQUIRE.
Extensive SYLOGIN.COM or LOGIN.COM command procedures slow down application startup. Many of the operations performed in a SYLOGIN.COM or LOGIN.COM are meaningless for DECwindows application startup. Therefore, the SYLOGIN.COM and LOGIN.COM files should be conditionalized for DECwindows application startup performance. When starting a DECwindows application, only a minimum of SYLOGIN.COM and LOGIN.COM commands should be executed. Typically, the commands that should be executed are the redefinition of DECW$USER_DEFAULTS (if present), and other logical name definitions if the user will be referencing them from within the context of a DECwindows application. The following code segment can be inserted into SYLOGIN.COM and LOGIN.COM immediately following the commands necessary for DECwindows:
$ mode = f$mode()
$ tt_devname = f$trnlnm("TT")
$ session_mgr_login = (mode .eqs. "INTERACTIVE") .and. -
(f$locate("WSA",tt_devname) .ne. f$len(tt_devname))
$ session_detached_process = (mode .eqs. "INTERACTIVE") .and. -
(f$locate("MBA",tt_devname) .ne. f$len(tt_devname))
$ if session_mgr_login .or. session_detached_process then exit
|
Applications continue to run even if these lines are not added to the SYLOGIN.COM and LOGIN.COM files.
If you are logging into DECwindows Motif and using a private logo command file, input focus might revert unexpectedly to the Username field when the private logo starts up.
Stopping the Session Manager process abruptly can have serious consequences for nonprivileged workstation users. DECwindows must be restarted to avoid the following problems:
Use the STOP/NOEXIT command to stop the process. Otherwise, stop the Session Manager process, and restart DECwindows (if you have system manager privileges) with the following command:
$ @SYS$MANAGER:DECW$STARTUP RESTART |
This section contains release notes pertaining to the DECwindows Motif Window Manager.
To change the title of the icon box on a system running HP DECwindows Motif for HP OpenVMS Alpha Version 1.3 or greater, edit the DECW$MWM.DAT file (in DECW$USER_DEFAULTS or DECW$SYSTEM_DEFAULTS), and set the value of Mwm*title instead of Mwm*iconBoxTitle.
V1.3
Invoking help (by right-clicking) on a screen other than screen 0, displays a Bookreader window with no content.
If you want to display help on a multihead configuration using the right-click method, initiate the request from screen 0.
With most Motif implementations, the Alt+space key combination prompts the Window Manager to display the Window menu. However, DECwindows Motif maps the Alt+space key binding to the Compose Character function. This provides a method for character composition on keyboards which do not supply a specific Compose Character key.
To change the Alt+space key binding so that it displays the Window menu, follow the procedure appropriate to your desktop environment.
For New Desktop systems:
Alt<Key>space icon|window f.post_wmenu |
For Traditional DECwindows Desktop systems:
Alt<Key>space icon|window f.post_wmenu |
V1.2
If you are using the color customizer provided in the DECW$EXAMPLES directory to control Motif Window Manager colors, the Motif Window Manager customization dialog boxes used to modify those colors may not reflect the correct current color values. This is normal behavior; use the color customizer instead of the Motif Window Manager color customization dialog boxes to change these values. Alternatively, exit the color customizer and then restart Motif Window Manager. See HP DECwindows Motif for HP OpenVMS Alpha New Features for more information about the color customizer.
The configuration file DECW$MWM_RC.DAT defines how the Window Manager uses the function keys. Most of the accelerators use the form Alt key (or Compose Character key) and function key, for example Alt+F7.
If any application needs to use these keys, you must either comment them out by placing an exclamation point (!) at the beginning of the line, or create new keyboard bindings. Then change Mwm*keyBindings:DefaultKeyBindings in the MWM resource file to point to the new bindings.
With the Motif binding, you can no longer use the Alt+spacebar or the Compose Character+spacebar to bring up the Window menu because it interferes with Compose Character sequences in DECterm. Use Shift+F11 to bring up the Window menu.
To reenable Alt+space, select the appropriate option in the Workspace Options dialog box and apply the current settings. You can also remove the comment for the default button bindings for Alt+space in the DECW$MWM_RC.DAT file.
The file SYS$MANAGER:DECW$MWM.COM is used for information on how to restart the Window Manager. By default, it is always restarted on all the screens that are available. However, if you are not starting the Window Manager from the Session Manager, then the Window Manager might not have been initially started on all the available screens. You can modify this file to change the way the window is restarted for your system.
The Motif Window Manager does not support full customization of color-related resources for monochrome monitors in the Options dialog box. In order to change the colors, you might need to modify the pixmap resources by directly editing the DECW$MWM_BW.DAT resource file. For example, to change the color of the active window's title background, you must change the Mwm*activeBackgroundPixmap resource. Some values include 25_foreground, 50_foreground, 75_foreground, and unspecified pixmap.
In addition, by default, the title text is created with a white background. To use the same color as the rest of the title, set the Mwm*cleanText resource to FALSE.
If you have a multihead system with different monitor types (color, monochrome, or gray-scale), you can customize the colors only by using the Options dialog box on the monitors that match the type of your main monitor (screen 0). To customize the other monitors, you must either log in to a system with that monitor type or directly edit the resource files.
If you move the icon box to the edge of the screen and then resize it using the keyboard, you can move it off the screen. To retrieve the icon box, press Alt+Tab until you reach that window and then press Shift Escape (F11) to bring up the Window menu for that window. You can then move the window back onto the screen.
The Window Manager does not center all the lines of a multiline icon title.
This section contains notes related to X Window System utilities that have been ported to DECwindows Motif.
This section contains release notes pertaining to the X Authority utility (xauth).
V1.3
The X Authority utility (xauth) does not support file locking when files are specified using a logical name. Since xauth does not translate OpenVMS logicals, it creates the lock files in the current default directory versus the directory specified by the logical.
For example, the following xauth command creates the lock files in the current default directory not in the USER directory specified by the logical XAUTH_FILE:
$ DEFINE XAUTH_FILE DISK:[USER]FILE.DECW$XAUTH $ XAUTH -f XAUTH_FILE |
In order to use logical names with xauth, translate each logical before invoking xauth, for example:
$ XAUTH_FILE = F$TRNLNM ("XAUTH_FILE")
$ XAUTH -f 'XAUTH_FILE'
|
Note that this restriction only pertains to using logical names with xauth and does not apply when using logical names with the SET DISPLAY/XAUTHORITY_FILE command.
V1.3
The X Authority utility (xauth) cannot differentiate between files and directories of the same name if the file does not yet exist and the type is not specified. For example, the following xauth command creates a set of lock files but does not create the X authority file:
$ CREATE/DIRECTORY [.TEST] $ XAUTH -f TEST |
In this case, xauth fails without reporting an error.
To prevent this problem from occurring, always specify a file type when specifying an X authority file.
This section contains release notes pertaining to the Print Screen utility.
V1.2--3
When using the Print Screen application to produce PostScript output on some printers, part of the output may be lost. Usually, the upper and left portion is missing when printing in landscape mode and the lower and left portion is missing when printing in portrait mode. This problem is caused by differences between PostScript printers.
To correct this problem, DECwindows Motif for OpenVMS Version 1.2--5 added support for four resources that can be specified in DECW$PRINTSCREEN.DAT:
PrintScreen.plxtranslate PrintScreen.plytranslate PrintScreen.plxscale PrintScreen.plyscale |
These resources control the size and position of the PostScript image on the page. The plxtranslate and plytranslate resources control the x and y offsets of the image in inches from the origin. The plxscale and plyscale resources are an x and y scale factor to allow the entire image to be displayed on the page after the origin is moved.
