D-Flat Version 14
The source files in the DFLAT archive constitute the D-Flat windowing
system. This is public domain code. You may use it in your
applications without restriction. You may freely distribute source
code. It would be nice if you would give credit to Dr. Dobb's Journal
as the original publisher of the source code.
The software build procedure makes a program named memopad.exe. It is
a multiple-document notepad program. Observe the #define VERSION
statement in dflat.h. The version number should correspond with the n
in the DFLATn.ARC and DFnTXT.ARC filenames that you downloaded. Check
the uploads periodically to see if there is a more recent version
available.
My CompuServe ID is 71101,1262. I monitor the DDJFORUM every day and
prefer that you discuss D-Flat there so that every one can benefit
from your comments.
============== Microsoft C 7.0
To build with Microsoft C 7.0, type this command
C>nmake /f makefile.msc
========== Borland C++ 3.0 ============
To build with the Borland C++ 3.0 make utility:
Set the DRIVE macro in the makefile to the drive where your compiler
is installed.
Type this command:
C>make /fmakefile.bcc
========== WATCOM C 8.0 ============
To build with Watcom C 8.0, type this command
C>wmake /f makefile.wat
=======================================================
D-Flat uses Compressed help files. It uses an adaptation of the
Huffman compression programs from the Dr. Dobb's Journal C
Programming Column of early 1991. If the program finds the compressed
MEMOPAD.HLP, it loads it. Otherwise, it looks for MEMOPAD.TXT, the
ASCII version of the file, and loads that file instead. When you
execute the Reload Help command on the Help menu, the program loads
the same way. To test changes to the help file that you make from the
MEMOPAD program, delete the MEMOPAD.HLP file so that the reload
command loads the MEMOPAD.TXT file. You can compress MEMOPAD.TXT into
MEMOPAD.HLP later. The program starts faster without compressed
help.
To compress the help file type this on the command line:
C>huffc memopad.txt memopad.hlp
Note that the makefile automatically rebuilds the help database.
If you are making source code changes and updating the help database
during the same development cycle, disable the automatic building of
the help database so that you may continue to change memopad.txt from
the memopad program and reload it immediately.
===============================================
This is version 14. It fixes these problems:
1. The COMBOBOX would display its Listbox when the dialog box was
opened if the COMBOBOX was the first control on the dialog box.
2. Document windows did not display properly when they were selected
with the mouse while the application window had the focus.
3. The Window/Close All command did not work properly in all cases.
4. Simultaneously scrolling and marking text with the mouse hung the
system under some circumstances.
5. Could not delete the last character of an editbox under some
conditions.
6. Zero-length text files caused problems for memopad.
7. Console.c had an errant geninterrupt(0x28) from one of my own
off-beat uses of D-Flat.
8. WatchIconProc and its prototype did not agree with respect to
static. The QuickC compiler does not like that.
9. Radio buttons sometimes did not reset properly leaving more than
one radio button selected in a group.
10. The applicat.c and helpbox.c/decomp.c code were not reusable. If
a program shut D-Flat down and then tried to use it again, the system
locked up.
11. Removed the far keyword from dfalloc.c so that other than large
memory models would work.
12. The INSERTTEXT message did not work properly.
