   3 D-Flat Version 20
   4
   5 The source files in the DFLAT archive constitute the D-Flat windowing
   6 system. This is public domain code. You may use it in your
   7 applications without restriction. You may freely distribute source
   8 code. It would be nice if you would give credit to Dr. Dobb's Journal
   9 as the original publisher of the source code.
  10
  11 The software build procedure makes a program named memopad.exe. It is
  12 a multiple-document notepad program. Observe the #define VERSION
  13 statement in dflat.h. The version number should correspond with the
  14 nn in the DFLTnn.ZIP filename that you downloaded. Check the uploads
  15 periodically to see if there is a more recent version available.
  16
  17 For other examples download the Quincy and IMail applications. The
  18 IMail application uses the DFWRAP C++ class wrapper.

  20 My CompuServe ID is 71101,1262. I monitor the DDJFORUM every day and
  21 prefer that you discuss D-Flat there so that every one can benefit
  22 from your comments.

  24 ========== Borland C++ 3.1 or 4.0 ============
  25
  26 To build with the Borland C++ 3.1 or 4.x make utility:
  27
  28 Set the DRIVE macro in the makefile to the drive and directory
  29 where your compiler is installed.
  30
  31 Type this command:
  32
  33     C>make /fmakefile.bcc
  34
  35 =======================================================
  36
  37 D-Flat uses Compressed help files. It uses an adaptation of the
  38 Huffman compression programs from the Dr. Dobb's Journal C
  39 Programming Column of early 1991.
  40
  41 The makefile compresses the help file with these commands:
  42
  43    C>huffc memopad.txt memopad.hlp
  44    C>fixhelp memopad.hlp
  45
  46 Both of the programs must be run in order for the help system to work
  47 properly. Note that .hlp files from previous versions are not
  48 compatible with versions 18 and higher. The .txt files are, however,
  49 so you can use the huffc and fixhelp programs to rebuild the .hlp
  50 file.
  51
  52 ===============================================
  53
  54 This is version 20. It incorporates these changes:
  55
  56 1. Dialog boxes displayed twice upon open.
  57
  58 2. The intended #define of FA_DIREC in direct.c was inadvertently
  59    released with #include as the preprocessing directive.
  60
  61 3. Changed status bar to display time after screen takeover.
  62
  63 4. Statbar incorrectly captured clock with every MOVE message. Caused
  64    hangups when compiled with BCC 3.1 and user moved application window.
  65
  66 5. Modeless dialog boxes did not redisplay properly when there was
  67 more than one window open.
  68
  69 6. Added ButtonEnabled and CheckBoxEnabled functions.
  70
  71 7. Changed LB_SETSELECTION message to accept -1 to turn off
  72 selections in the listbox.
  73
  74 8. Moved processing of ID_SEARCH, ID_SEARCHNEXT, ID_REPLACE, ID_CUT,
  75 ID_COPY, ID_PASTE, ID_DELETETEXT, ID_UNDO, and ID_CLEAR to editbox.c,
  76 relieving applications of these common processes.
  77
  78 9. Now allow marking blocks, cut, copy, paste, etc. on single line
  79 editboxes.
  80
  81 10. Added SetProtect function.
  82
  83 11. The Window menu listed doc windows that were not visible.
  84
  85 12. Changed class identifiers to Class.
  86
  87 13. ClearWindow did not work properly for a window with a status bar
  88 and menu bar and no title bar.
  89
  90 14. Added the void *wrapper field to the window structure to support
  91 a C++ class wrapper around the D-Flat C function library.
  92
  93 15. Sizeable windows with borders now display a small token in the
  94 lower right corner to indicate that they are sizeable.

  98 Buy the DDJ CD-ROM from Miller-Freeman to get the complete D-Flat
  99 narrative from May '91 to October '92. These columns describe the
 100 development of D-Flat and serve as a tutorial on its use. The D-Flat
 101 reference manual is DFLAT.DOC.
