Text File | 1995-12-20 | 17.5 KB | 489 lines

------- Released BLT 1.9.0 Dec 20, 1995 --------------

* Updated to compile with either Tk4.0 or Tk4.1a2.  Removed all compatibility
with Tk3.6.  Added HP-UX 10 to recognized shared library compilations.

* Fixed some reported bugs (isn't that helpful).

* Added 'cget' method to BLT's 3 widgets to support SpecTcl.  Required
renaming some fonts and adding bogus -relief option to blt_htext.

* removed entire 'applications' subdirectory.  kosherdill was way out of
date, and extloader has been subsumed by tcl7.5a2.

------- Released BLT 1.8 --------------

Sun Jul  2 17:26:58 1995  Jeffrey Hobbs ([e-mail])

    * Tons of stuff changed internally.  Works with Tcl 7.4, Tk 4.0 ONLY


OLD CHANGELOG:

Fri Apr 22 09:08:05 1994  George_A_Howlett  (gah@grenache)

    * src/bltGrAxis.c (GetAxisGeometry): Changed tick label allocation
    scheme to allocate a single character pool, instead of multiple
    allocations for each label.

Wed Apr 20 20:18:33 1994  George_A_Howlett  (gah@grenache)

    * src/bltBitmap.c (DefineBitmap): Fixed bug of elemArr
    being freed twice (in cases where bitmap is already defined).

Fri Mar 11 11:37:19 1994  George_A_Howlett  (gah@grenache)

    * src/bltGrAxis.c (axisNames): Fixed order of axis names.

    free-ed in CleanupProc while other traces could still be
    pending for it.  Thanks to Greg Schmid (sp?)
    ([e-mail]) for the report and fix.

Thu Feb 24 09:27:54 1994  George_A_Howlett  (gah@grenache)

    * src/bltGrPS.c (Blt_PrintLine): Note that variable i should

    * src/bltGrTag.c (PrintLine): Scratch buffer was appended
    twice to interp->result in line tag print routine.  Many
    thanks to Lou Salkind ([e-mail]) for the report

    min or max or stack bar segments with both positive and negative
    values.

Wed Feb  2 15:43:33 1994  George_A_Howlett  (gah@grenache)

    * README: Updated for BLT-1.4


Tue Feb  1 09:34:39 1994  George_A_Howlett  (gah@grenache)

    * src/bltGraph.c (WindowCoords): Was returning an extra list
    around the coordinate values.  Thanks to Wolf D. Ihlenfeldt
    ([e-mail]) for the fix.

Mon Jan 31 12:00:19 1994  George_A_Howlett  (gah@grenache)

    * src/bltGrTag.c (Blt_TagCmd): Bad check for wrong # args in the
    "tag coords" command.  Thanks to Wolf D. Ihlenfeldt
    ([e-mail]) for the fix.

    * src/bltGrTag.c (lineConfigSpecs): Changed -width option to
    -linewidth. Now agrees with the manual. Thanks to Wolf
    D. Ihlenfeldt ([e-mail]) for the fix.

    * src/bltGrTag.c (bitmapConfigSpecs): Changed -pattern option to
    -bitmap. Now agrees with the manual. Thanks to Wolf D. Ihlenfeldt
    ([e-mail]) for the fix.

Thu Jan 27 11:59:51 1994  George_A_Howlett  (gah@grenache)

    * src/bltGrAxis.c (Blt_ComputeLayout): Calculations for tick
    labels are slightly off, causing x and y2 axes to be cut off when
    the axis title is displayed.  Remedy by adding half the title font
    height to balance things.

Wed Jan 26 11:26:30 1994  George_A_Howlett  (gah@grenache)

    * src/bltGrElem.c (ClosestElement): Reversed the order in
    searching elements, from last drawn to first.  When two elements
    have the same closest data point, we want to select the one drawn
    last.  Thanks to Wolf D. Ihlenfeldt ([e-mail])
    for the fix.

Fri Jan 21 09:47:15 1994  George_A_Howlett  (gah@grenache)

    * src/bltWatch.c (Blt_WatchInit): Created new command "blt_watch".
    Calls "pre" and "post" Tcl procs before and after Tcl commands.
    Allows for simple tracing, profiling, debugging routines to be
    created.  Needs a good variable trace demo.

    * src/bltHtext.c (CreateTraces): Changed command argument of
    Tcl_Eval from a static string to prevent "gcc"-compiled versions
    from dumping core.  Thanks to [e-mail] for the
    bug-report.

    * src/bltHtext.c (GotoLine): Off-by-one error when bounding
    gotoline values.  Thanks to Doug ([e-mail]) for the fix.

    * src/bltGrElem.c (UpdateVector): Added call to
    GetDataLimits(vecPtr) so that element autoscales correctly.
    Thanks again to Joe VanAndel ([e-mail]), who has
    found and fixed (sadly far too) many bugs in the blt_graph C
    interface.

Wed Jan 19 11:50:07 1994  George_A_Howlett  (gah@grenache)

    * src/bltGrAxis.c (UpdateLimits): Fixed axis limits when only one
    of the limits (either min or max) is autoscaled.  Was possible to
    have manual limit conflict with auto.

Tue Jan 18 15:52:24 1994  George_A_Howlett  (gah@grenache)

    * src/bltGrAxis.c (UpdateLimits): Set arbitrary axis limits before
    testing the range.  Thanks to Gordon Lack ([e-mail]) for
    the bug report.

    * src/bltDragDrop.c:
    Changes static char * values to #defines. Make use strdup().
    Check if malloc-ed pointers are NULL before deallocating.
    Thanks to [e-mail] for the patch.

    Added tokenOutline an configuration option.

    * src/bltGrAxis.c: Added prevMin, prevMax fields to Axis
    structure.

Mon Jan 17 18:26:54 1994  George_A_Howlett  (gah@grenache)

    (xAxisConfigSpecs, etc.):  Removed "Axis" from option
    names. Only option classes has "Axis" now.  Created
    configSpecs for alternate axes (x2 and y2).

Mon Jan 10 17:26:53 1994 George_A_Howlett (gah@grenache)

    * feature (bltGrAxis.c, bltGrTag.c, bltGrElem.c)
      - added alternate x-axis (x2).
      - added -mapx, -mapy options (removed -axis) to tags
        and elements
      - can map element or tag to both axes, but elements still get
        mapped to first axis.
      - removed axis title options from general widget configuration.

Thu Jan  6 18:38:33 1994  George_A_Howlett  (gah@grenache)

    * Changed kosherdill-1.0 directory to kosherdill.

    *  bugfix (kosherdill) main.tcl
      - removed suppression of drag&drop error messages
      - added check to make sure that "send" command is operational

        * bugfix (Makefile.in) Added missing \ to install-dirs target.
      Thanks to Dan Mack ([e-mail])

    * new features (blt_barchart/blt_graph):

      Added alternate y-axis.  New ipad and pad options to legend.
      Data vectors are allocated in doubled-size chunks.  Element line
      segments are pre-calculated and saved in SegInfo structure.

    * bugfix (bltBgexec.c)

          Introduced bug in last release. FixNewline and UnfixNewline
      called with wrong number of arguments.  Many thanks to Dan Mack
      ([e-mail]), Mark Sterin ([e-mail]), Elchonon
      ([e-mail]), and Cary Renzema
      ([e-mail]) for their bug reports and fixes.

    * bugfix (bltGrAxis.c)

          Introduced bug in last release. Reported errors when empty
      strings passed as arguments to axis -min, -max options.  Thanks
      to Tim Medley ([e-mail]) and Gordon Lack ([e-mail])
      for their bug reports and fixes.

    * feature (bltGrAxis.c, bltGrTag.c bltGrElem.c) extra y-axis.
      Added secondary y-axis "y2".
      New axis configuration option: -mapped

      New element configuration option -axis: select which y-axis to
      map element y-coordinates onto.

      Added -axis option to all tags.  Indicates which y-axis to
      map tag y-coordinates onto.

    * feature (AppendVector, UpdateVector)
      use more efficient size-doubling algorithm for adding space
      to the vector.

    * feature (bltGrLegd.c)
      New configuration options: ipadx, ipady, padx, pady


    * bugfix (bltTable.c) Called LayoutTable with too few arguments.

Thu Dec 16 15:42:50 1993  George_A_Howlett  (gah@grenache)

    * bugfix (all) Command initialization routines all now
    return TCL_OK or TCL_ERROR (instead of void).

    * bugfix (bltInit.c) All calls to BLT command initialization
    routines are checked for TCL_OK.  The first error knocks
    you out of the BLT init routine.

    * bugfix (all) All source files now include blt.h.  Includes
    prototype for Blt_FindCmd (remove prototypes from files).
    Also, move include directives for <stdlib.h> and <string.h>
    into blt.h.  Now checks HAVE_STRLIB_H, HAVE_STRING_H before
    attempting to include.

    * bugfix (all) Added prototype for strdup(). Check for sun,
    since the SunOS 4.x and 5.x prototypes conflict.

    * bugfix (all)  Removed prototype of toupper(). Was causing
    errors on other systems.

    * bugfix (bltGrMisc.c) Added replacement routines for
    strcasecmp() and strncasecmp() if the C library doesn't
    contain either of them.

    * bugfix (bltGraph.h, bltGrAxis.c bltGrElem.c bltGraph.c)
    Removed all references to math routines exp10, rint, sincos,
    fabs, and abs.  Supply replacement macro definitions instead.
    This is to facilitate dynamic loading of a shared BLT library.
    Can't add math routines not already used in libtcl.a.

    * bugfix (bltGraph.h bltGraph.c) Look for MAX_DBL and
    MIN_DBL in ANSI float.h instead of using HUGE_VAL.  Will
    still use HUGE_VAL for non-ANSI compilers, except for Sun.
    On SunOS 4.x, don't want to drag in __infinity from math
    library.  Will provide hard numbers instead.  If HUGE_VAL
    can't be found, use HUGE.  Again, this facilitates dynamic
    loading of BLT as a shared library.

    * bugfix (bltGrMisc.c) Removed sincos, exp10 replacements.

    * bugfix (bltGrElem.c) Check for odd number of coordinates in
    in "element append" command.

    * bugfix (bltGrElem.c) In Blt_GraphElement(), don't append data.
    Reset the element data instead.   Also, mark the element for re-
    layout.  Thanks to Joe VanAndel ([e-mail]) for
    the patch.

    * bugfix (bltDragDrop.c) "source" option with no arguments was
    trying to return configuration information for NULL window

    * feature (bltGraph.c) Added -halo configuration option.  Sets
    a threshold distance when searching elements for closest points.

    * feature (bltGrElem.c) Added "element closest" command.  Searches
    elements for closest point, returning list of information.

    * feature (bltGrElem.c) Added element -activeforeground and
    -activebackground options with "element activate" command.
    Highlights data points using the element's active colors.

    * feature (bltGraph.c) Added "transform" command.  Transforms
    graph coordinates into window coordinates.  Also changed "locate"
    command to "invtransform".

    * bugfix (bltGrElem.c) Data print routines now use Tcl dynamic
    strings instead of malloc-ing own space.

    * feature (bltGrElem.c) Barchart element -foreground option now
    can take a list of colors.  Extra colors are used with elements
    containing multiple y data points.

    * feature (bltGrTag.c) Changed "tag identifiers" command to
    "tag ids".

    * bugfix (bltGrTag.c) Check number of arguments for tag command.

    * bugfix (bltGrTag.c) Test for "-Inf" and "Inf" before trying
    Tcl_ExprDouble.  On sun's this is automatically converted to
    -HUGE_VAL and HUGE_VAL.

    * feature (bltGraph.h, bltGraph.c, bltGrHairs) Added -color
    option to crosshairs.

Wed Nov 24 14:15:59 1993  George_A_Howlett  (gah@grenache)

    * bugfix (bltInit.c, etal) Changed format of Blt_*Init
    routines to extension proposal.

Wed Nov 24 12:06:38 EST 1993  Michael_J_McLennan  (mmc@gewurtz)

    * bugfix (bltUtil.c)  Removed error message from Blt_FindCmd.

    * bugfix (kosherdill/Makefile.in) Added space to sed command.
    Thanks to Mark Brucks ([e-mail]) for the fix.

    * bugfix (kosherdill/Makefile.in) Failed to create new library
    directory properly.

    * bugfix (configure.in)  Made BLT_LIBRARY a separate configurable
    variable.  Don't assume install directory to be @prefix@/library.
    Thanks to Scott Schwartz ([e-mail]) for
    the report.

Fri Nov 19 17:21:32 1993  George_A_Howlett  (gah@grenache)

    * ------- Released BLT-1.0 -------

=======
    * bugfix (bltDragDrop.c) Fixed memory leak for drag&drop
    source handlers.

------- Released BLT-1.0 -------

>>>>>>> 1.2
Sat Nov 13 18:01:15 1993  George_A_Howlett  (gah@grenache)

    * feature (kosherdill) BLT's first application!  Probes
    your file system for large and moldy files. Many thanks
    to Michael McLennan ([e-mail]) for adding it
    to the BLT distribution.  It's also a great demonstation of
    the new "blt_drag&drop" command.

    * bugfix (bltHtext.c) Added TK_CONFIG_NULL_OK flag to
    -filename option. This allows clearing of the widget by
    simply configuring the filename to the empty string.

    * bugfix (bltHtext.c) Reverse search was completely wrong.
    Thanks to Allan Brighton ([e-mail]) for the
    fix.

    * bugfix (bltHtext.c) Scanning was improperly scaled by
    x or y scrollunits.

    * bugfix (bltHtext.c) Errors in configuring the htext
    widget were not properly propagated back. Removed all that
    "goto redisplay" silliness. Thanks to Micheal McLennan
    ([e-mail]) for the report.

    * feature (bltDebug.c)  A simple command trace facility.
    It's interface and functionality will probably change in the
    next release.

    * feature (bltInit.c, src/Makefile)  Added a new variable
    $blt_library indicating where the graph prolog and drag&drop
    protocols are.  Can be set by BLT_LIBRARY variable and is
    defined in the library.

    * feature (bltDragdrop.c) Micheal McLennan has
    ([e-mail]) gratiously added his wonderful
    drag&drop facility (he still maintains it).  See the "palette"
    demo.

    * feature (bltBgexec.c) Added -outputvar switch to
    "blt_bgexec" command.  I keep putting switches after the
    output variable name, when it should be before. So maybe
    this is more intuitive.  The old syntax still works.

    * change:  Eliminated use of Imakefiles altogether. This
    was prompted by the new shared library target.  I still
    like imake, but don't want to mediate the differences
    between R4 and R5 imake.

    * feature (Makefile) Added install targets for demo, library,
    shared library, and manuals.   Thanks to Scott Schwartz
    ([e-mail]) for the suggestion. Shared
    library target only knows about SunOS, Solaris, and HP-UX
    right now.

Fri Oct 15 17:17:12 1993  George_A_Howlett  (gah@grenache)

    * bugfix (bltGrTag.c) Added missing options -xoffset
    and -yoffset to the text tag.  Thanks to Mike Halazar
    ([e-mail]) for the fix.

    * feature (bltBgexec.c) Added switches to "blt_bgexec"
    command (-keepnewline, -updatevar, -errorvar). Can now
    collect stderr in a variable.  Also can get updates
    of data as it is read from the pipe.  See demo "bgexec".

Wed Sep 29 20:58:01 1993  George_A_Howlett  (gah@grenache)

    * bugfix (bltHtext.c) Event handler and hash table entry
    for child subwindows were not being removed when freeing
    lines or when a child window was destroyed.  Thanks to
    Micheal McLennan ([e-mail]) for the fix.

    * feature (bltHtext.c) Added "children" option to display
    all the child windows the htext widget thinks it has. It
    was for debugging, but I'll leave it in anyway.

Mon Sep 20 13:08:33 1993  George_A_Howlett  (gah@grenache)

    * bugfix (bltTable.c) Changed number of arguments passed to
    ConfigureCubicle.  Now conforms with usage in TableCmd.
    Thanks to Angel Li ([e-mail]) for the
    fix.

------- Released BLT-1.0b2 -------

Fri Sep 10 10:50:39 1993  George_A_Howlett  (gah@grenache)

    * bugfix (configure.in) Added tests to check for bogus
    math library functions sincos and rint.

Thu Sep  9 13:00:50 1993  George_A_Howlett  (gah@grenache)

    * bugfix (bltGraph.h, bltGrMisc.c) for HP architectures
    sincos() and rint() return bogus results.  Thanks to John
    Robert LoVerso ([e-mail]) for tracking it down and
    supplying the fix.

    * bugfix (grconf.tcl, busy) clean up demos

    * bugfix (configure.in) search for TK_LIBDIR failed to look
    in ../tk3.3b3.  Added non-beta directory names to search.

    * bugfix (bltGrElem.c) Data vectors for lines and bar were
    not released.

    * bugfix (bltGrLegd.c) Memory for legend structure was not freed.

    * bugfix (bltGrPS.c) Memory for postscript structure was not freed.

    * (bltGrMisc.c) removed unused Blt_CreateGC routine.

Wed Sep  8 11:22:32 1993  George_A_Howlett  (gah@grenache)

    * bugfix (tkAppInit.c) Replaced with tk3.3b3 version.  Thanks to
    Philippe Defert ([e-mail]).

    * bugfix (configure.in) TCL_INCDIR and TK_INCDIR mistakenly have
    tcl.h and tk.h suffixes for certain configurations. Thanks to
    Gerald Fowler ([e-mail]).

------- Released BLT-1.0b1 -------
