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.
