HELP XNEWS Apr 1995 NOTE: See HELP * X in order to find out how to make Poplog/X facilities available. --------------------------------------------------------------- CONTENTS - (Use <ENTER> g to access required sections) 1 Version 14.5+ News 2 Version 14.5 News --------------------- 1 Version 14.5+ News --------------------- 1995 Jun 23 (Robert Duncan) Changes to the Motif XmText and XmTextField widget classes: --- Memory leaks associated with the procedures XmTextFieldGetSelection XmTextFieldGetString XmTextGetSelection XmTextGetString have been fixed --- New procedures added for Motif 1.2: XmTextDisableRedisplay XmTextEnableRedisplay XmTextFieldGetSubstring XmTextFindString XmTextGetSubstring These are documented in the Motif 1.2 Programmer's Reference Manual. Apr 26 (Robert Duncan) Fixes to LIB * PROPSHEET: --- the attribute default = item in a field definition is now treated identically to the assignment item -> propsheet_field_default(field) i.e., the item may be an identifier or procedure as well as a plain value, and will have converters, etc., applied as appropriate for the field --- the behaviour of propsheet_apply has been modified for fields which have an apply procedure set with propsheet_field_applier: the value parameter passed to the apply procedure is now the result of calling propsheet_field_value on the field; this ensures that the value is consistent with what is displayed to the user and has conversions already applied 1994 Apr 14 (John Gibson) --- XptDeferApply is now an (obsolete) synonym for the new procedure * external_defer_apply. The latter is an autoloadable library, implemented differently from the old XptDeferApply: external_defer_apply uses sys_raise_signal to raise its procedure argument p as an asynchronous trap, but specifying that p be blocked inside external calls. Thus when inside external calls, p is queued, and will not be executed until the next interrupt checkpoint encountered on returning from the outermost external call. The queueing of p also causes an implicit XptSetXtWakeup to be performed when inside a Toolkit callback; hence an explicit call of XptSetXtWakeup is no longer needed following external_defer_apply. -------------------- 2 Version 14.5 News -------------------- Oct 08 (Jonathan Meyer) --- Added XptShellDeleteResponse, for specifying an action which is called when the user closes the window. --- Added XptResizeResponse, for specifying an action which is called when a widget is resized. Jul 09 (Adrian Howard) --- * XptXrmValuePtr and * XptXrmValueList shadowclasses moved from LIB * XT_CONVERTER to LIB * XPT_GENERAL. See REF * XPT_GENERALTYPES. Jul 08 (Adrian Howard) --- * XptCheckXrmDatabase and * XptCheckValidValuePtr added to LIB * XPT_TYPECHECK. See REF * XPT_TYPECHECK for details. Jul 07 (Adrian Howard) --- LIB * PROPSHEET now provides the procedure propsheet_field_number to return the index of a propsheet field. See TEACH * PROPSHEET/propsheet_field_number for details. Jul 05 (Adrian Howard) --- * XDefaultColormapOfScreen, * XDefaultDepthOfScreen, * XScreenNumberOfScreen, and * XDefaultVisualOfScreen added to LIB * XPT_SCREENINFO (with associated "fast" procedures in LIB * FAST_XPT_SCREENINFO.) See REF * XPT_SCREENINFO for details. --- * XAllocID now fixed. See REF * XlibMacros for details. --- * XptScreenPtrApply now also accepts "default_cmap" to return a screens default colormap, and "number" to return a screens numerical index. See REF * XPT_CLASSAPPLY for details. --- The following procedures have been added to LIB * XlibMacros: * XConnectionNumber * XDisplayString * XRootWindow * XDefaultDepth * XDefaultRootWindow * XNextRequest * XDefaultGC * XLastKnownRequestProcessed * XAllPlanes * XScreenOfDisplay * XQLength * XDefaultScreenOfDisplay * XDisplayWidth * XVendorRelease * XDisplayHeight * XImageByteOrder * XDisplayWidthMM * XBitmapBitOrder * XDisplayHeightMM * XBitmapPad * XDisplayPlanes * XBitmapUnit * XScreenCount * XDefaultScreen * XServerVendor * XDefaultColormap * XProtocolVersion * XDefaultVisual * XProtocolRevision * XDisplayCells and See REF * XlibMacros for details. Jun 30 (Adrian Howard) --- Fast versions of the procedures in LIB * XPT_SCREENINFO are now supplied in LIB * FAST_XPT_SCREENINFO (for details see REF * XPT_SCREENINFO.) --- LIB * XPT_SCREENINFO has been extended with the following procedures: # * XCellsOfScreen # * XMinCmapsOfScreen # * XMaxCmapsOfScreen # * XDoesSaveUnders # * XDoesBackingStore # * XEventMaskOfScreen LIB * FAST_XPT_SCREENINFO has the corresponding "fast_" procedures. See REF * XPT_SCREENINFO for full information. --- * XptDoesBackingStore supplies a more user friendly interface to * XDoesBackingStore --- * XptScreenPtrApply has been extended to provide information related to the new functions in LIB * XPT_SCREENINFO. --- * XtDatabase and * fast_XtDatabase added to LIB * XT_RESOURCE and LIB * FAST_XT_RESOURCE. These enable the resource database associated with a specified display to be accessed. See REF * XT_RESOURCE for details. --- Support for * XptXrmDatabase structure added. See: # * XptImportXrmDatabase (REF * XPT_COERCE) # * XptXrmDatabase (REF * XPT_XTYPES) # * XDT_XRMDATABASE (REF * XPT_CONSTANTS) --- Added * XVisualIDFromVisual (see REF * XVisuals.) --- Added missing visualid and killid fields to the * XStandardColormap structure (see REF * XColormaps.) --- Added * XSetRGBColormaps, * XGetRGBColormaps, and * ReleaseByFreeingColormap to LIB * XColormaps. See REF * XColormaps for full informations. --- * XptCheckScreenPtr now supplied in LIB * XPT_TYPECHECK for testing XptScreenPtr XptDescriptors. Jun 18 (Adrian Howard) --- Only shell widgets now have destroy actions associated with them. Since the children cannot become garbage before their parents the destroy actions on non-shell widgets were redundant. Apr 30 (John Gibson) --- From Version 14.22 of Poplog, XptWidgetSet is redundant (at least, for all the standard widget sets supported by Poplog). See Widget Set Interfaces in REF * XT_LIBS for details of the new setup. The procedures XptLoadClass and XptLoadClassProc are replaced by the (pseudo-exload) macros * XptLoadWidgetClass and * XptPopLoadProcedures respectively (described in REF * XT_LIBS, Macros For Loading Procedures & Widgetclasses). XptWidgetSet and its associated procedures will (of course) continue to operate as before. The change was necessary because the XptWidgetSet interface was not suitable for use with POPC object-module compilation, which requires that global structures such as widgetclasses and their associated procedures reside in specific identifiers, generated by specific files. Nov 30 (Adrian Howard) --- The destruction of a display now causes all the widgets associated with a display to be destroyed before that display is closed. See XtCloseDisplay and XtDestroyApplicationContext for more information. Nov 11 (Adrian Howard) --- New variable XptDefaultFallbackResources which allows you to specify fallback resources for XptDefaultDisplay. See *XptDefaultFallbackResources for more information. Oct 13 (Adrian Howard) --- Two new procedures fast_XptWidgetOfObject and XptWidgetOfObject added. See REF *XT_WIDGETINFO *XptWidgetOfObject for more information. Sep 22 (Adrian Howard) --- Improvements made to the XVed search and replace dialogs: o Buttons now grey out if there is nothing to search for. o Searches made by the user on the status line cause the fields in the dialog boxes to update. --- XtSetSensitive and fast_XtSetSensitive (see REF *XT_EVENT) now work --- The "New" and "Edit..." options on the PUI file tool now place appropriate VED commands on the status line --- Improvements made to LIB *PROPSHEET o A single identifier can now be linked to more than one PROPSHEET field. o Under Motif the insert cursor does not move when the contents of a text field are accessed. Sep 14 (Adrian Howard) --- XVed windows with scroll bars under Motif can now be resized to a single line without an error. Sep 13 (John Gibson) --- A new syntax construct XptVal allows efficient accessing and updating of multiple widget resources. See REF *XPT_RESOURCE. Sep 11 (Adrian Howard) --- Items in the PUI Help-Tool are now deselected after they have been viewed. Sep 10 (Adrian Howard) --- Added a new name key "tree" to LIB *XPT_WIDGETAPPLY which returns the widget-tree rooted at the specified widget. See REF *XptWidgetApply for more information. --- Fixed problems in the PUI and LIB *PROPSHEET which caused dialogs to pop-down prematurely. Sep 04 (Adrian Howard) --- The Motif PUI Help-Tool now works correctly when pop_pr_quotes is true. --- You can now select multiple documentation types and subsystems under the Motif PUI Help-Tool. Sep 03 (Adrian Howard) --- The '-do' option to the stand alone "xved" command now works. ********** FOR EARLIER NEWS ITEMS SEE HELP * XNEWS_V14.2 *********** --- C.x/help/xnews --- Copyright University of Sussex 1995.
