Test release 4.50.91
--------------------
* Lots of bugfixes and code cleanup by Tobias Oed, see ChangeLog.

Release 4.50.5
--------------
* Fix for XmNautoFill in XbaeInput when the pattern begins with an
  optional literal, such as [-]d[d][d][d][d] .
* Add the new resources introduced in the last months to the example
  Builder Xcessory integration file in examples/builderXcessory.
* Bugfix for a clip window size problem that showed up when resizing the
  window (e.g. resize examples/traversal/traversal to smaller than the
  original and then bigger). Bug #702560.
* Some source code cleanup.
* Fixes by James Georgas for colour handling.
* Fixes by Van to eliminate slider size warnings (see bugs #823041 and #823037).
* Fixes by David Traill for both resize and scrollbar warnings.
* Add XmNXmColumnLabel resource to handle XmString as column labels.
* Fix a memory problem with row_heights.

4.50.3 was not an official release.
	It was a test version distributed to parties interested in it.

Release 4.50.2
--------------
* A memory (double free) related bugfix.
* Two new resources (XmNhorzFill, XmNvertFill) were added to allow for 
  additional fill behaviour. This allows you to specify how the matrix
  treats highlighting of the last row or column.
* The foreground and background resources are no longer being set on
  cell widgets, as this appears to be strange behaviour.
* Bugfix related to incorrect refresh after deleting rows.
* Remove some C++ style comments.
* Fix some build problems.
* Move some stuff in the share/ directory at installation.
* Implement the XBAE_PRODUCTION symbol to compile Xbae with or without
  debugging code.
* Improve resizing rows and columns.
* Avoid X Errors when setting clip geometry to 0.
* Implement showColumnArrows and showRowArrows resources.
* Fix incorrect behaviour when rapidly clicking with two different
  mouse buttons.
* Fix nested comments and a missing prototype.
* Fix scrollbar warning problem.
* Changed the column width measurement.

Release 4.50
------------
This is a stable release, basically equivalent to 4.9.13.

Changes in 4.9.13
-----------------
* Fix the GROHTML build problem.
* Bugfix : when resizing first of trailing fixed rows, the VSB slider
  was not updated and a blank area was visible between clip and bottomclip.
* Changed useXbaeInput default value to False.

Changes in 4.9.11
-----------------
* Sascha Göbel and Greg Shebert are now part of the Xbae development team.
* Many bugfixes to the scrolling (smooth scrolling now),
  and to resizing row heights.
* Received code from Sasha Göbel.

Changes in 4.9.9
----------------
* Bug fixes related to redrawing.
* Enable dynamic row/column resizes again.
* Include images in release files again - this makes for a large package.
* Build HTML manual pages from their sources (the HTML is in doc/,
  but the sources are in src/*.3.in).

Changes in 4.9.7
----------------
* Sascha Göbel contributed substantial improvement to scrolling.
* Bugfixes.

Changes in 4.9.5
----------------

* Improved internal debugging support (dmalloc, dbmalloc)
* Fix pattern check in XbaeInput
* Remove support for Motif <=1.1
* Bugfix by Phil Eccles to position cell widgets correctly when row/column
  headers are active.


Changes in 4.9.1
----------------

Xbae now stand-alone project on sf.net:
  http://xbae.sf.net

  
Changes in 4.9.0
----------------
* Row height and true-color (aka 24-bit color) support are now considered stable
  and enabled by default.
* Internals : try to give all non-static functions an Xbae prefix.
* Code contributed by Frank Mair for having bold columns in XbaeMatrix.
* Bugfixes.


Changes in 4.8.x
----------------

Xbae is now maintained by the LessTif Development Team
(see http://www.lesstif.org)

A detailed list of changes to the library can be found in
the ChangeLog file.

Comments, questions, bugs & postcards can be directed to the
LessTif mailing list <lesstif@lesstif.org> .

* Resizable rows

* TrueColor support


Changes in 4.7.2
----------------
* CELL_WIDGETS fixes by Linas Vesptas.

* CELL_WIDGETS functionality extended with XbaeMatrixGetCellWidget()
  which you can use to figure out whether a cell already has a
  widget.

* CELL_WIDGETS now enabled by default, and somewhat implemented.


Changes in 4.7.1
----------------
* Maintenance is transferred to the LessTif core team.

* Configuration based on automake, autoconf, libtool is added, this
  is the preferred environment for the current (new) maintainers.


Changes in 4.7
----------------

* Swapped out the XmTextField widget to use the XmText widget to enable
  multi line rows and the like - thanks to Mark Gibson (magibso@uswest.com)
  for his methods in achieving this goal.

* Added a patch from Philip Aston (philipa@parallax.co.uk) that
  reportedly speeds up things by 300% when using pixmaps.  Acheivable
  by specifying the width, height and depth of a pixmap to an
  XbaeMatrixDrawCellCallbackStruct.

* Another patch from Philip provided correct behaviour when setting
  the XmNsensitive resource on ancestors of the matrix widget.

* "Ceklosky" (b1dqza9@is200005.bell-atl.com) reported a memory leak
  when the widget was destroyed.  This came about from highlighted-
  cells not being freed.

* Donato Petrino (dp@rtsffm.com) provided an efficient way of detecting
  if partially displayed rows were visible

* He also supplied a patch that corrected the placement of the text
  widget if the user first clicked on an editable fixed row.

* Scott Harrington (scotth@ibl.bm) figured out that xbaeComputeSize()
  should not add space for scrollbars if the displayPolicy is set to
  XmDISPLAY_NONE.  He also provided a patch.

* Made a small change to a conditional in Matrix.c that prevents
  an erroneous warning message being displayed.  Thanks to Curt
  Malouin (cmalouin@ford.com) for that one.

* Merged two patches from Jay Schmidgall (Jay.Schmidgall@Sungardss.com)
  one fixed a slight error in the drawing of scrollbar heights/widths
  while the other fixed some casting problems under Solaris [they
  must be getting stricter on this ANSI C thing!]

* Brian McAllister (brian@hotrats.mit.edu) provided a fix for compilation
  of Xbae on Dec Alphas

* Jay Schmidgall continued work on the widget, providing:

o Corrected some bugs with row/column shadow drawing and clearing
o Corrected some bugs related to not having row/column labels
o Changed the way shadows are drawn to be the correct way,
  i.e., mine. That is, XmSHADOW_OUT results in an outset shadow.
  Note: this may have implications for Motif 1.1 compatibility,
  since type isn't passed along to _XmDrawShadow()
(ED: Since 1.1 is no longer supported, this isn't an issue!)
o Changed the grid type enumeration to be more explicit
o Made the unneeded grid types deprecated, which will result
  in runtime warning messages
o Added grid types XmGRID_ROW_LINE and XmGRID_COLUMN_LINE
  (this was suprisingly simple :)
o Modified the matrix resource declaration to come into line
  with grid/shadow changes
o Modified the choice example program to reflect these changes
o Modified the man page to reflect these changes

*** NOTE ************************************************************
  The new types for gridType are:
  enum
  {
      XmGRID_NONE             = 0x00,
      XmGRID_CELL_LINE        = 0x02,
      XmGRID_CELL_SHADOW      = 0x03,
      XmGRID_ROW_LINE         = 0x04,
      XmGRID_ROW_SHADOW       = 0x05,
      XmGRID_COLUMN_LINE      = 0x08,
      XmGRID_COLUMN_SHADOW    = 0x09,

      /* Deprecated types. Use will cause
       * a run-time warning to be issued. */
      XmGRID_LINE             = 0x20,
      XmGRID_SHADOW_IN        = 0x40,
      XmGRID_SHADOW_OUT       = 0x80
  };

  If any of the bottom three values, a runtime warning will be output.
  You simply need to tweak the resources in your app to avoid it.

*********************************************************************

* Added a patch supplied by Martin Helmling (mh@octogon.de) that
  correctly manages the insensitive pixmap when creating for multiple
  screens.  Patches were also sent in by Dimitri Castiglioni and
  Donato Petrino.

* Added the doc/XbaeMatrix.man.html file as part of the official release

* Jay Schmidgall sent in another patch!  This time he:

o got irritated by how the matrix did column shadows/lines.
  In particular, there could be a little gap between the last
  non-fixed row and the first trailing fixed row, and that gap
  looked bad because the column shadow just ended there. So,
  I modified the shadow & highlight code so that gap got filled
  in. Looks much better now.
o Fixed the column resize shadow so it draws all the way to the
  bottom of the matrix, plus handles the gap like the above.
o Added a new resource, XmNtrailingAttachedBottom. (If you can
  come up with a better name, feel free :). This resource makes
  the matrix keep the trailing fixed rows on the bottom. It only
  has effect when XmNfill is true and there are trailing fixed
  rows. It's probably easier to understand visually.
o I put the equivalent AttachedRight in the matrix's resources,
  but I didn't feel up to doing the code for it :).
o Added a bunch of macros.
o Added the resource to the man page (yay!)
o Mucked around some more with the choice program to add the
  attachedBottom resource, and let you change the selection mode.
  I did this mostly because choice is the test bed for changes I
  make, and I needed to test the highlighting. Also let you do
  Arm mode, which looks neat in the grid shadow modes.

* Philip Aston sent in yet another patch that remedied an array
  bounds read as reported by Purify.

* A segmentation fault occurred if the user pressed <ESC> when no
  cells had been defined.  Diligently spotted and patch provided
  by Noel Yap (nyap@garban.com)

* Removed an unnecessary reference to XmNeditVerifyCallback in
  Matrix.h that Noel found as well.

* Added fix from Jon Sibala (jon_sibala@hotmail.com) where zero 
  rows was causing a crash in xbaeDrawCell.

* David North reported a bug in the charWidth macro on OpenVMS.
  A cast to unsigned char of the passed character was required.

* Marty Leisner (leisner@sdsp.mc.xerox.com) advised that the runtest
  script required '.' to be in your path.  Added an explicit ./ to
  all commands run from the script

* Cleaned up a few potential problems with compilation

* Removed the xqCellWidget from the release. The subclassed widget
  started causing problems when using Motif 2.1 probably due to
  incompatibilities between the XmText and XmTextField widgets
  The change may also fix problems reported by the guys back at
  Bellcore, running under Motif 2.1

* There are some new public functions:- XbaeMatrixSetRowLabel and,
  funnily enough, XbaeMatrixSetColumnLabel and their Get equivalents
  are now documented in the man page.

* Just as some sort of benchmark, Callum and myself loaded up a
  historical database comprising of somewhere around 780,000 rows and
  3 columns.  Using the drawCellCallback, XbaeMatrix handled display
  of the data as if there were 100 rows.  If anyone has tried creating
  a bigger table, please let me know the results!  (That applies to
  tables created with commercial widgets too)

* The building of shared libraries is now the default behaviour in
  the Imakefile.  If anybody has trouble running the demos due
  to the shared library not being picked up, please let me know
  so we can work out a fix.

* The HTML man page is probably a bit behind as I prefer methods
  from yesteryear.  Updates are always appreciated!

* Removed a strdup call and added __EMX__ to the preprocessor directives
  for not having bcopy.  Patch sent in by Evgeny Stambulchik
  (fnevgeny@plasma-gate.weizmann.ac.il)

* Two fixes from Mark Crowther (markc@parallax.co.uk) that better
  controlled scrolling with the pointer outside the clip and prevented
  the scrollbar warnings when columns were deleted.

* Noel Yap (nyap@garban.com) pointed out a small error in the draw
  example where the columns for pixmaps was incorrect

* Added the XEvent structure to all callbacks

* New widget!  XbaeInput allows a 'pattern' to be specified to restrict
  input to certain characters.  Read the new man page to find out
  more.

* Added some extra parameters to the XbaeMatrixEnterCellCallbackStruct -
  namely, position, pattern, auto_fill, convert_case, and
  overwrite_mode for use with the XbaeInput widget.
  Also, the params and num_params are passed through to the
  enterCellCB too.

* New resource - XmNcalcCursorPosition that allows the pointer to
  specify the insert position when clicked on a cell to be edited
  rather than at the end (default is False so behaviour is unchanged)

* Nick Banyard (nbanyard@micromuse.com) provided the ability to
  allow multibyte characters to be displayed with the addition of an
  XFontSet.  There is a new example program also, named multibyte
  that *should* display multibyte characters but some work may be
  needed there.

* Mark Hatch (mhatch@ics.com) provided me a free copy of Integrated
  Computer Solutions (http://www.ics.com) Builder Xcessory for both
  Solaris and Linux so the integration and compatibility between the
  two can be maintained.  If you're looking for an excellent GUI builder,
  I'd recommend checking this one out!

* Added a matrix creation convenience routine - XbaeCreateMatrix for
  smoother integration into Builder Xcessory

* Added a caption creation convenience routine - XbaeCreateCaption for
  smoother integration into Builder Xcessory

* Added an input creation convenience routine - XbaeCreateInput for
  smoother integration into Builder Xcessory

* Evgeny Stambulchik (fnevgeny@plasma-gate.weizmann.ac.il) supplied the
  GNU autoconf tools needed to compile the widget via ./configure as so
  many people feel the urge to do nowadays.  However, I have no intention
  of supporting it so you'd better have a friend who can & will.

* Callum Gibson (callum.gibson@aus.deuba.com) wrote a couple of new
  public functions to refresh entire rows or columns efficiently.
  They are called XbaeMatrixRefreshRow() and XbaeMatrixRefreshColumn().

* The XbaeMatrixAnyCallbackStruct was created to allow the reason, 
  event, row and column members to be aligned and facilitate the use
  of one callback struct in multiple callbacks.

* Fixed a bug with wrong fg/bg colours when editing a cell with
  reverse select enabled and using a draw cell callback which set
  foreground or background. (Everyone does that don't they?)

* Added a new action that allows the matrix to be scrolled up and
  down using the PgUp/PgDn keys when the text field is mapped.  It
  is installed by default.
