1 Version 14.2 News
--------------------
Aug 25 (Adrian Howard)
--- The procedure -fast_XtDisplayOfObject- is now autoloadable.
--- The XpwGraphic widget methods -XpwAllocColorRange- and
-XpwFreeColorRange- now work correctly.
--- The default values of the following XpwScrollText widget
resources are now correct:
XtNmenubarForeground
XtNmenubarBackground
XtNscrollbarForeground
XtNscrollbarBackground
--- The procedure -XptGetFontProperty- now returns -false- if the
font property atom name is unknown.
--- The typespecs in INCLUDE *XPT_XEVENT.PH are now correct.
--- Displays opened via -(fast_)Xt(Va)AppInitialize- are now closed
properly after a -sysfork-.
--- In LIB *PROPSHEET -propsheet_show- and -propsheet_hide- now
work correctly for imported property boxes.
--- Bug in -XptDefaultDisplay- which caused multiple displays and
application contexts to be created has been fixed.
--- The POPLOG UI file tool, help tool, and exit prompt now work
as expected when -pop_pr_quotes- is -true-.
--- Selecting lines in XVed now works when -vedleftmargin- is
non-zero.
--- There are two new XVed application resources (DialogBackground
and DialogForeground) which alter the foreground and background
colours of the XVed specific dialog boxes. See REF *XVED for
more information.
--- Setting the XVed menubar and scrollbar foreground and background
colours now works correctly.
Jul 01 (Adrian Howard)
Features added to make X behave better after a -sysfork-:
--- The destroy actions for widgets, application contexts, and
displays are now stored in -sys_process_destroy_action- and are
cleared in the child process after a -sysfork-
(see REF *XptDescriptor, *SYS_PROCESS_DESTROY_ACTION.)
--- The variables -XptDefaultDisplay- and -XptDefaultAppContext- are
reset to -false- in the child process after a -sysfork- so
-XptDefaultSetup- can be used in the new process.
(see REF *XT_INIT)
--- All displays and application contexts are closed in the child
process after a -sysfork-. X processing on a display should only
occur in the same process it is created in.
Jun 29 (John Gibson)
--- The procedures XptAsyncDisplay, (fast_)XptInterruptHandler and
XptDisplayDevice have been withdrawn. (Support is no longer
provided for access to a server device. XptAsyncAppcontext
supports asychronous event handling.)
Jun 23 (Adrian Howard)
Changes from Jon Meyer installed:
--- New OLIT functions and widget classes added to
LIB *OpenLookWidgetSet
--- LIB *PROPSHEET rewritten and extended
--- Procedure -XpmCoerceCopiedString- added
--- New library LIB *XPM_LISTUTILS added
May 28 (Adrian Howard)
--- The procedure -XptCheckWindowedWidget- has been added to the
library LIB *XPT_TYPECHECK to check that a given widget is a
subclass of the Core widget class
--- The procedure -fast_XtIsWidget- is now an autoloadable. This
allows its usage to increase error detection in other functions
(eg, -XptCheckWindowedWidget-.)
Apr 29 (Adrian Howard)
--- The procedure -XptDefaultSetup- now behaves correctly if it
cannot open a display. Also, if -XptDefaultDisplay- contains
a string when -XptDefaultSetup- is called, the string is used
as the name of the display to be opened.
Mar 30 (Adrian Howard)
--- The procedures -fast_XtRemoveCallback-, -XtRemoveCallback-,
-fast_XptRemoveCallbackList- and -XptRemoveCallbackList- no
longer mishap if an attempt is made to remove a callback not
registered from POP-11.
Feb 24 (Adrian Howard)
--- Installed changes to LIB *RC_GRAPHIC suggested by John
Cunningham:
o New procedure -rc_draw_oblong- to draw rectangles with
rounded corners.
o The shell of -rc_window- has its "input" resource
controlled by the -rc_wm_input- variable
Feb 21 (Adrian Howard)
--- Facilities have been added to support multiple toolkit versions.
A new variable -XLINK_VERSION- has been added which represents
the version of the libraries specified in -XLINK_LIBS-. This can
be specified in INCLUDE *XDEFS, or set by LIB *NEWPOP when a new
Poplog system is built. See REF *X and HELP *NEWPOP for more
information.
For information on how -XLINK_VERSION- should be set for
different versions of OLIT, see REF *OPENLOOK.
--- The procedures -LookupOlColors- and -OlGetApplicationResources-
become redundant in all OLIT versions after 2.0.
--- The procedure -OlListItemPointer- has been added to the support
for the OLIT ScrollingList widget.
--- The XpOLListItemPtr shadowclass and the OlListItem typespec are
now defined appropriately depending on the OLIT version being
used.
Feb 17 (Adrian Howard)
--- -XptDestroyWindow- now autoloads separately from -XptNewWindow-.
Jan 24 (Adrian Howard)
--- Added -XGetGCValues- to LIB *XGraphicsContext to allow clients
to read the current values of a given graphics context.
Jan 23 (Adrian Howard)
--- Added -XpwStackColorRangeInfo- to LIB *Xpw/XpwGraphic. Fetches
the same information as -XpwColorRangeInfo- without creating a
vector. See REF *XpwGraphic.
Jan 20 (Adrian Howard)
--- Added Xt keyboard handling libraries (see LIB *XT_KEYBOARD and
LIB *FAST_XT_KEYBOARD) which provide facilities for case
conversion and translating KeyCodes to KeySyms. For details see
REF *XT_KEYBOARD.
--- Two new external callback types added, CaseProcs & KeyProcs. See
REF *XT_CALLBACK and REF *XT_KEYBOARD for details.
--- The -XptImportKeySymTable- procedure added to allow
XptKeySymTables to be imported from the Intrinsics. For details
see REF *XPT_COERCE.
--- XptIntPtr shadowclass added to LIB *XPT_GENERAL.
--- New $-Xpt section added. All identifiers in this section are
reserved for Poplog X implementors.
Jan 13 (Jonathan Meyer)
--- Added the "BellVolume" XVed application setting, allowing you
to change the volume of the beep produced by vedscreenbell.
Jan 12 (Jonathan Meyer)
--- Installed C.all/x/Xpw/ExposeEvent.c, which is used by XpwPixmap
and XpwGraphic to generate synthetic exposure events. This is
used in places where, previously, XClearArea would have been
called with a final argument of TRUE. It is an improvement on
XClearArea because there is no longer a flicker when you perform
the operation. Places where this used to happen were: switching
the pixmapStatus from PixmapOff to PixmapOn in the XpwGraphic
widget, and using XpwPutImage and XpwDrawImage.

2 Version 14.1 News
--------------------
NOTICE: NAME CHANGE IN SHADOWCLASS RECORDS
==========================================
Due to a change in the behaviour of shadowclass, a number of non-upward
compatible functional/name changes have been introduced into the
toolkit. The following shadowclasses are affected:
XpawTextBlock XptGCValuesPtr
XpmAnyCallbackStruct XptOptionDescList
XpolListItem XptOptionDescRec
XptActionList XptResouceList
XptActionsRec XptResource
XptArg XptResourceListPtr
XptArgList XptSubstitution
XptCallbackList XptSubstitutionRec
XptCallbackRec XptXrmValue
XptConvertArgList XptXrmValueList
XptConvertArgRec XptXrmValuePtr
Users whose programs use these shadowclasses should examine the entry
dated Nov 4th in detail.
NOTICE: USE OF -FAST- POPLOG X TOOLKIT PROCEDURES
=================================================
a) From Poplog 14.1, the functionality of all of the fast_ X toolkit
procedures which register Pop-11 procedures with the X toolkit
has been changed. Such procedures no longer perform coercion on their
arguments to convert a Pop-11 procedure into an externally callable one.
This means that code which does things like:
fast_XtAddCallback(w, XtN buttonEvent, foo, 'string');
will no longer work - instead you need to do:
fast_XtAddCallback(w, XtN buttonEvent,
XptExportCallbackCached(foo, 'string', false),
);
The non-fast versions of the procedures are unchanged.
b) Using fast procedures which are built into the binary
The -fast- X toolkit procedures built into the Poplog binary should not
be used without first loading the Pop11 fast_xt_ library associated with
the procedures. For example, you should not use the -fast_XtDisplay-
procedure unless you have added a line of code saying 'uses
fast_xt_display' at the top of your program. This will protect you
should any of these procedures in future move out of the core of Poplog.
Doing <ENTER> ref fast_XtDisplay will tell you what the name of the
relevant fast_xt_ library is.
-----------------------------------------------------------------------
Nov 7 (John Gibson)
--- Since Version 14.0, there have been quite a number of changes
to the functionality of the XpwScrollText widget-class. The most
important changes are
o The widget now maintains its own representation of the
text in the window, and deals with exposure events
automatically (the callback that previously handled
exposures has now gone).
o Button event handling now deals automatically with filtering
'clicks', and passes data in a different format to the
XtNbuttonEvent callback.
o Row 0 in a window has its own foreground/background colours
(for the status line in XVed).
o There are various other new resources.
See REF *XpwScrollText for full details.
Nov 5 (Adrian Howard)
Action and ActionHook procedures now pass -XptXEventPtr-
structures rather than external pointers.
Nov 4 (Adrian Howard)
Due to a change in the behaviour of shadowclass, a number of
non-upward compatible name changes have been introduced into the
toolkit. The libraries that have been affected are listed below:
LIB *XptGCValuesPtr
This library no longer creates -typespec:XptGCValuesPtr-,
but uses -typespec:XptGCValues- as defined in INCLUDE
*XPT_XTYPES.PH.
The subscript procedures for the fields in -XptGCValuesPtr-
shadowclass structures now have the prefix "XptGCV" rather
than "XptGCVP" (see the -XptGCValues- typespec).
LIB *XT_ACTION
The -XptActionsRec- shadowclass defined in this library has
been renamed -XptActionsPtr-.
The library no longer creates -typespec:XptActionsRec-. This
typespec is now defined in INCLUDE *XPT_GENERALTYPES.PH.

now -XptActionsPtr- structures (instead of -XptActionsRec-).
LIB *XT_CALLBACK
The -XptCallbackRec- shadowclass defined in this library has
been renamed -XptCallbackPtr-.
The library no longer creates -typespec:XptCallbackRec-.
This typespec is now defined in the file INCLUDE
*XPT_GENERALTYPES.PH.
The components of -XptCallbackList- shadowclass structures
are now -XptCallbackPtr- structures (instead of
-XptCallbackRec-).
LIB *XT_CONVERTER
The -XptXrmValue- shadowclass defined in this library has
been renamed -XptXrmValuePtr- (the old -XptXrmValuePtr-
structure has been removed).
The -XptConvertArgRec- shadowclass has been renamed
-XptConvertArgPtr-.
The library no longer creates -typespec:XptXrmValue- and
-typespec:XptConvertArgRec-. These typespecs are now defined
in INCLUDE *XPT_GENERALTYPES.PH.
The components of -XptXrmValueList- and -XptConvertArgList-
shadowclass structures are now -XptXrmValuePtr and
-XptConvertArgPtr- structures (instead of -XptXrmValue- and
-XptConvertArgRec).
-XptColorConvertArgs-
-XptScreenConvertArg-
The -XptConvertArgList- shadowclass structures contained in
these autoloadable constants are now made from
-XptConvertArgPtr- structures rather than -XptConvertArgRec-
structures.
LIB *XT_RESOURCE
The -XptResource- shadowclass defined in this library has
been renamed -XptResourcePtr-.
The library no longer creates -typespec:XptResource-. This
typespec is now defined in INCLUDE *XPT_GENERALTYPES.PH
The components of an -XptResouceList- shadowclass structure
are now accessed via -XptResourcePtr- structures (rather
than the old -XptResource- shadowclass).
The -XptResourceListPtr- shadowclass has been removed (it is
the equivalent of the -XptResourceList- shadowclass.
LIB *XT_UTIL
The library no longer creates -typespec:XptSubstitutionRec-.
This is now defined in INCLUDE XPT_GENERALTYPES.PH
The shadowclass -XptSubstitutionRec- has been renamed
-XptSubstitutionPtr-.
The components of an -XptSubstitution- shadowclass structure
are now accessed via -XptSubstitutionPtr- structures (rather
than the old -XptSubstitutionRec- shadowclass).
LIB *XPT_GENERALTYPES
The typespec declarations previously contained in this
library are now in INCLUDE *XPT_GENERALTYPES.PH, the
shadowclass declarations are now in LIB *XPT_GENERAL.
Loading XPT_GENERALTYPES compiles both of these files.
The -XptArg- and -XptOptionDescRec- shadowclass have been
renamed -XptArgPtr- and -XptOptionDescPtr-.
The components of -XptArgList- and -XptOptionDescList-
structures are now accessed via -XptArgPtr- and
-XptOptionDescPtr- structures (rather than the old -XptArg-
and -XptOptionDescRec- shadowclasses).
-XptVaArgList-
This procedure now accepts -XptArgPtr- shadowclass
structures instead of -XptArg- structures.
LIB *Xaw/XawText
The -XpawTextBlock- shadowclass has been renamed
-XpawTextBlockPtr-.
The typespecs -typespec:XawTextBlock- and
-typespec:XawTextBlockPtr- have been renamed
-typespec:XpawTextBlock- and -XpawTextBlockPtr-.
The field names of -typespec:XpawTextBlock- (and the
-XpawTextBlockPtr- shadowclass) have been renamed to
"XpawTBFirstPos", "XpawTBFormat", "XpawTBString",
"XpawTBLength".
LIB *Xm/XmConstants
Typespec -typespec:XmAnyCallbackStruct- renamed
-typespec:XpmAnyCallbackStruct- and its fields renamed to
"XpmACSReason" and "XpmACSEvent".
The -XpmAnyCallbackStruct- shadowclass renamed
-XpmAnyCallbackStructPtr-.
LIB *Xol/XolScrolling
The -XpolListItem- shadowclass has been renamed as
-XpOLListItemPtr-.
Oct 31 (Adrian Howard)
Several changes to LIB *FAST_XT_EVENT and LIB *XT_EVENT.
o Coercion of booleans now takes place in LIB *FAST_XT_EVENT
o Type-checking bugs fixed
o EventHandlers now assume a -true- result if a Pop11 callback
does not return a result.
o There is now proper coercion of Pop11 procedures via:
-XptExportEventHandler(Cached)-
-XptExportInput(Cached)-
-XptExportTimeOut(Cached)-
These replace the old coercion procedures -XptCoerceTimeOut-,
-XptCoerceEventHandler-, and -XptCoerceInput-.
o EventHandler procedures are now held in widget records to
prevent early garbage collection.
o Pop11 EventHandler procedures are now passed an -XptXEventPtr-
rather than an external pointer.
See REF *XT_EVENT for details.
Sep 30 (Adrian Howard)
--- Added -XptImportUnregisteredDisplayPtr- to import display
pointers that do not have an associated application context
into Pop11. See REF *XT_DISPLAY for details.
--- -XtOpenDisplay- now allows a -false- (null) display and/or
application name string.
--- Added -XptExportActionCached- to LIB *FAST_XT_ACTION.
Sep 25 (Jonathan Meyer)
--- XpwGraphic resource XtN usePrivateGC has been removed.
(It provided no useful functionality).
Sep 23 (Adrian Howard)
--- LIB *XT_CONVERTER and LIB *FAST_XT_CONVERTER improved:
o There is now proper coercion of Pop11 procedures via:
-XptExportTypeConverter(Cached)-
-XptExportDestructor(Cached)-
-XptExportConvertArgProc(Cached)-
These take the place of the previously incorrect
coercion procedures -XptCoerceTypeConverter- and
-XptCoerceDestructor-.
o Support for -ConvertArgProc- procedures added.
o Several bug fixes and improvements on type-checking in
LIB *XT_CONVERTER.
o -(fast_)XtDisplayStringConversionWarning- added.
o Support for -XptCacheRef-, -XptXrmValueList-, and
-XptCacheRefPtr- structures added.
See REF *XT_CONVERTER for full details.
Sep 18 (Adrian Howard)
--- Installed the library LIB *XPT_WIDGETTYPES which gives
typespecs for core and composite widgets. See REF
*XPT_WIDGETTYPES for details.
--- Added the constant -XptXrmQuark- to LIB *XPT_XTYPES.
Sep 11 (Adrian Howard)
--- All the toolkit procedures which take "list" structures now
check that they are of the appropriate length, or are
null-terminated. See the -XptCheckNT<TYPE>- and
-XptCheck<TYPE>AndLength- procedures in REF *XPT_TYPECHECK
for details.
Sep 6 (Jonathan Meyer)
--- Poplog now sets the X toolkit error and warning handlers to
print output using Poplog's cucharerr, via *sysprmessage.
Also, error message name/type information is printed for
errors generated using the X toolkits higher level error
message interface.
Sep 5 (Adrian Howard)
--- You can now pass a null XEvent pointer to -XtCallActionProc-
--- There is now proper action (hook) coercion via the
procedures:
-XptExportAction-
-XptExportActionHook-
-XptExportActionHookCached-
These procedures replace the previously incorrect coercion
procedures -XptCoerceAction- and -XptCoerceActionHook-. See
REF *XT_ACTION for details.
--- Removed obsolete callback tracing constants
-XptCBTypeTimeout-, -XptCBTypeCallback-, -XptCBTypeInput-,
-XptCBTypeAction-, and -XptCBTypeActionHook- from INCLUDE
*XPT_CONSTANTS. For details of the new callback tracing
mechanism see REF *XT_CALLBACK.
Sep 1 (Jonathan Meyer)
--- Added facilities for defining arbitrary new widget callback
lists and for creating and managing cursor planes.
See REF *XPT_CURSORPLANE*XPT_CLIENTCALLBACK.
Code in LIB *XPT_CURSORPLANE*XPT_CLIENTCALLBACK
LIB *XptGarbageCursor*XptGarbageCursorFeedback
LIB *XptBusyCursor*XptBusyCursorFeedback
Aug 29 (Adrian Howard)
--- Added the constants -XtCallbackNoList-, -XtCallbackHasNone-,
and -XtCallbackHasSome- to INCLUDE *XT_CONSTANTS.
--- There is now proper callback coercion via the procedures:
-XptExportCallback-
-XptExportTypedCallback-
-XptExportCallbackCached-
-XptExportTypedCallbackCached-
These procedures replace the previously incorrect coercion
procedures -XptCoerceCallback- and -XptCoerceTypedCallback-
which have been withdrawn. See REF *XT_CALLBACK for details
of callback coercion.
Aug 28 (Julian Clinton)
--- The 'Poplog User Interface' for X Windows has been installed
in C.all/x/ui. LIB *POPLOG_UI loads it.
Aug 23 (Adrian Howard)
--- The procedure -XtAppSetFallbackResources- now allows a null
fallback resources XptStringList.
Aug 21 (Adrian Howard)
--- HELP *XPOP_NEWS renamed HELP *XNEWS
HELP *XPOP_NEWS.V13_9 renamed HELP *XNEWS.V13_9
HELP *XPOP renamed HELP *X
HELP/TEACH/REF *XPOPINDEX renamed HELP/TEACH/REF *XINDEX
--- Fixed -Xt(Va)AppInitialize- so that null application context
pointer and fallback resource arguments are permitted.
Aug 20 (Jason Handby)
REF *XPOPTYPES renamed REF *XPT_TYPES.
Aug 19 (Jonathan Meyer)
Installed -XptEvenlySpaceWidgets- and -XptWidgetCoords-. See
REF *XT_LIBS.
Aug 1 (Jonathan Meyer)
The XptXEventPtr shadowclass has been renamed XptXEvent - its
field names have also been updated. Previously its name clashed
with the XptXEventPtr typespec in LIB *XptImportXEventPtr, and
meant that xt libraries could not be loaded with pop_debugging
-false-. The new name does not clash.
See LIB *XptXEvent for the specification of the new shadowclass.
Most users will have used the typespecs in INCLUDE *XPT_XEVENT
instead of the shadowclass, and so they will therefore be
unaffected by the change.
Aug 1 (Jonathan Meyer)
Installed INCLUDE *X_ATOMS and *X_KEYSYMS, X_CURSORFONT.
SEE REF *XT_LIBS
Installed LIB *XptGetFontProperty. See REF *XptGetFontProperty.
Installed LIB *XptWMShellCoords. See REF *XptWMShellCoords.
Jul 30 (Jonathan Meyer)
Tidied and improved Poplog Widget Set (fixed several bugs):
--- Renamed libXpw.a -> libXpw.olb to be consistent with other pop
object libraries. Moved the archive into $popexternlib and
removed redundant XPOPBIN and its directory.
Removed x/bin, x/com and x/plog directories, which are empty.
--- Added Xpw C source directory to popsrclist in LIB *POPXLIB,
so you can now do SRC *XpwGraphic.c.
--- Documented support for XpwLoadPixmap, XpwFreePixmap,
XpwGetPixmap, XpwFontAscent, XpwFontDescent, XpwFontHeight and
XpwTextWidth in REF *XpwCore.
--- Fixed bug in SRC *XpwPixmap.c so that XtNtile, XtNstipple etc.
resources work correctly. This means the following (documented)
resources will work (see REF *XpwPixmap):
planeMask fillStyle fillRule arcMode tile stipple
tileStipXOrigin tileStipYOrigin subwindowMode
clipXOrigin clipYOrigin clipMask dashOffset
--- Removed XpwFailureImport from PoplogWidgetSet.p and replaced
with more efficient version of XpwCallMethod, which correctly
imports colours and XID's. Also removed redundant calls to
xpw_check_live_widget and replaced with XptCheckWidget.
--- Documented XpwCreateImage, XpwFreeImage, XpwImagePixelValue
and XpwPixelValue in REF *XpwPixmap, and updated LIB *XpwPixmap.
Jul 4 (Jonathan Meyer)
--- Added support for Xt event handlers and raw Xt event handlers
See REF *XT_EVENT.
Added XptAncestors, XptShellOfObject. Improved XptChildren.
See REF *XT_LIBS.
Jul 2 (Andreas Schoter)
--- Full Athena Widget Set support added. See:
HELP *ATHENA, REF *ATHENA, TEACH *ATHENA
LIB *XawTutorial, LIB *AthenaWidgetSet,
LIB Xaw/Xaw*.p
Jul 1 (Jonathan Meyer)
--- Added RoundedRectangles to list of shapes supported by XpwPixmap
and XpwGraphic. (See REF *XpwPixmap, under
XpwDrawRoundedRectangle and XpwFillRoundedRectangle).
Jun 28 (Jonathan Meyer)
--- Added general purpose high level dialog box and property sheet
building library. SEE TEACH *PROPSHEET and LIB *PROPSHEET.
Works for MOTIF and OPENLOOK.
Jun 28 (Jonathan Meyer)
--- Added class apply convenience functions for descriptors (eg.
widgets, screens, displays, widget classes). Allows you to do
things like:
widget("parent")("width") +1 -> widget(2)("height");
See REF *XPT_CLASSAPPLY for details.
Jun 18 (Roger Evans)
--- Type-checking versions of Xt procedures which expect arglist
data now accept pop11 lists in place of (arglist,length)
arguments and process them using XptArgList automatically. Eg
the following now all behave identically:
1) XtCreateWidget(widget,class,parent,XptArgList(list));
2) XtCreateWidget(widget,class,parent,list);
3) XptArgList(list) -> (arglist,card);
XtCreateWidget(widget,class,parent,arglist,card);
The FAST versions of these procedures do NOT carry out this
coercion, however.
Jun 18 (Jon Meyer)
--- A draft REF *XVED is now installed.
--- XVed now uses OpenLook and Motif widgets
--- src xt_widget.p fixed to work with gadgets correctly.
May 30 (Jon Meyer)
--- XVed version 1.2 has been installed (this is the first version
of XVed to be placed in Poplog). Documentation to come shortly.
May 30 (Jon Meyer)
--- Xpw Version 5.0 has been installed - this should fix the clear
area bug. Documentation to come shortly.
May 30 (Jon Meyer)
--- XpolAddListItem was added to make it possible for Sun-3 clients
to add items to the OpenLook ScrollingList widget. See
REF *OPENLOOK/XpolAddListItem.
May 30 (John Gibson)
--- The change dated May 30 in HELP *NEWS concerning -exload- and
`runtime actions' affects -XptLoadProcedures- and
-XptWidgetSet-.
XptLoadProcedures uses the "=" form of -exload- directly, and so
any identifiers it loads will be affected as described in the
NEWS change.
XptWidgetSet uses internal mechanisms of -exload- which do the
equivalent of "=" operations. Procedure identifiers imported by
it are affected in the same way as for XptLoadProcedures. Widget
class structures, on the other hand, can still be accessed at
compile-time, but are not completely set up until run-time (and
so cannot be used until then).
May 24 (Jon Meyer)
--- Added *XptCenterWidgetOn and *XptMaxWidgetVisibility.
See REF *XT_LIBS.
Apr 25 (Ian Rogers)
--- Added -XptChildren- and -XptWidgetTree-. See REF *
XT_WIDGETINFO.
Apr 18 (Jon Meyer)
--- Added *XpolScrollingList to set OpenLook ScrollingListWidget
lists using Pop-11 lists or item repeaters.
Apr 17 (Ian Rogers)
--- Fixed XpwSetFont, XpwSetCursor, & XpwSetColor.
Apr 12 (Roger Evans)
--- Removed LIB XT_COMPAT and the entire compat directory. This
facility was intended to provide backward compatibility for
early (pre-release) versions of the X Toolkit interface, but
in fact it never worked properly anyway.
Mar 15 (John Gibson)
--- A new procedure -XptAsyncAppContext- enables full asynchronous
processing of toolkit events for a given application context.
This is intended as a replacement for -XptAsyncDisplay-, which
responds only to server events and not to toolkit
timers/alternate inputs (and which, owing to its reliance on
Unix SIGIO signals on sockets, is not portable to all POPLOG
hosts).
The new facility works uniformly across both wait and non-wait
states (i.e processing of events is either on or off, regardless
of what else POPLOG is doing). It is automatically enabled on
-XptDefaultAppContext- by -XptDefaultSetup-.
See REF * XptAsyncAppContext.
Feb 25 (Aaron Sloman)
--- Updated HELP * X with cross references to new documentation.
--- Fixed out of date cross references in
HELP * RC_GRAPHIC and TEACH * RC_GRAPHIC
Feb 16 (Jon Meyer)
--- Added MOTIF widget set demos, including:
TEACH *XmDemos, LIB *XmDemos, *XmDemoUtils,
LIB *XmDialogsDemo, *XmControlsDemo, *XmTextDemo
--- Changed XptWidgetSet so that widget set C procedures have some
basic argument processing and checking ( does basic string and
boolean coercion, and also checks for illegal datatypes,
where class_field_spec contains full objects, or is false).
Feb 15 (Jon Meyer)
--- Added MOTIF widget set interface, including:
HELP *MOTIF, REF *MOTIF, TEACH *MOTIF
LIB *MotifWidgetSet.p, LIB Xm/Xm*.p
--- Added Atom cache library, see LIB *XPT_ATOMCACHE and
REF *XPT_ATOMCACHE
--------------------
3 Version 14.0 News
--------------------
Jan 30 (Jon Meyer)
--- Added INCLUDE *XPT_XCOLOR *XPT_XFONTSTRUCT *XPT_XGCVALUES and
INCLUDE *XPT_XIMAGE with typespecs and macros for colors,
fonts, graphics contexts and images.
Jan 27 (Jon Meyer)
--- Added LIB *POPXDEMO (counterpart to POPXLIB). Also added
OpenLook demonstration programs (see HELP *XolDemos),
which are loaded using LIB *XolDemos
Jan 26 (Roger Evans)
--- shadowclass declarations in various libraries altered to
take account of non-upwardly compatible change in LIB
* SHADOWCLASS (see HELP * NEWS).
Jan 25 (Jon Meyer)
--- Tidied XLIB libraries (ie files in $usepop/pop/x/pop/lib/xlib,
as accessed via LIB * XLIB):
Removed remaining references to $Xroot from XLIB files.
Added new symbol XHASOLDX to xdefs.ph. This symbol is true if
and only if the library liboldX.a exists. It is used to allow
some of the XLIB libraries to load oldX functions if they are
available.
Moved include files from XLIB directory to main x include
directory and made them use INCLUDE_constant
--- Added new symbol XPOPDEMO to xdefs.ph. This contains the
pathname for the x demo directory - default value:
'$usepop/pop/x/pop/demo'
Jan 17 (Jon Meyer)
--- Moved the following libraries from the non-autoloadable into
the autoloadable x library directory:
LIB * XptArgList LIB * XptConvertUnit
LIB * XptGCValuesPtr LIB * XptNewWindow
LIB * XptWidgetSet LIB * XptXEventPtr
Fixed bugs in LIB * XpwGraphic and LIB * XpwPixmap
Tidied INCLUDE * XpwPixmap.ph (removing some extra XtN
definitions).
--- Installed the following documentation:
HELP * Xpw TEACH * Xpw
REF * XpwCallMethod REF * XpwMethods
HELP * OPENLOOK TEACH * OPENLOOK
--- Fixed LIB * OpenLookWidgetSet so that OlInitialize returns
a widget (previously returned an external_ptr).
1991
Jan 7 (Aaron Sloman)
--- Removed unnecessary check for integer args in rc_draw_rectangle
1990
Dec 11 (Aaron Sloman)
--- An extension to the RC_ library, written by David Young has been
installed, consisting of the following files.
LIB * RC_GRAPHPLOT, * RC_GRAPHPLOT2
TEACH * RC_GRAPHPLOT, HELP * RC_GRAPHPLOT
This provides a far more extensive collection of graph drawing
procedures than LIB * RC_DRAWGRAPH
