D-Flat Version 20
|
||
|
|
|
||
|
|
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
|
||
|
|
nn in the DFLTnn.ZIP filename that you downloaded. Check the uploads
|
||
|
|
periodically to see if there is a more recent version available.
|
||
|
|
|
||
|
|
For other examples download the Quincy and IMail applications. The
|
||
|
|
IMail application uses the DFWRAP C++ class wrapper.

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.

========== Borland C++ 3.1 or 4.0 ============
|
||
|
|
|
||
|
|
To build with the Borland C++ 3.1 or 4.x make utility:
|
||
|
|
|
||
|
|
Set the DRIVE macro in the makefile to the drive and directory
|
||
|
|
where your compiler is installed.
|
||
|
|
|
||
|
|
Type this command:
|
||
|
|
|
||
|
|
C>make /fmakefile.bcc
|
||
|
|
|
||
|
|
=======================================================
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
The makefile compresses the help file with these commands:
|
||
|
|
|
||
|
|
C>huffc memopad.txt memopad.hlp
|
||
|
|
C>fixhelp memopad.hlp
|
||
|
|
|
||
|
|
Both of the programs must be run in order for the help system to work
|
||
|
|
properly. Note that .hlp files from previous versions are not
|
||
|
|
compatible with versions 18 and higher. The .txt files are, however,
|
||
|
|
so you can use the huffc and fixhelp programs to rebuild the .hlp
|
||
|
|
file.
|
||
|
|
|
||
|
|
===============================================
|
||
|
|
|
||
|
|
This is version 20. It incorporates these changes:
|
||
|
|
|
||
|
|
1. Dialog boxes displayed twice upon open.
|
||
|
|
|
||
|
|
2. The intended #define of FA_DIREC in direct.c was inadvertently
|
||
|
|
released with #include as the preprocessing directive.
|
||
|
|
|
||
|
|
3. Changed status bar to display time after screen takeover.
|
||
|
|
|
||
|
|
4. Statbar incorrectly captured clock with every MOVE message. Caused
|
||
|
|
hangups when compiled with BCC 3.1 and user moved application window.
|
||
|
|
|
||
|
|
5. Modeless dialog boxes did not redisplay properly when there was
|
||
|
|
more than one window open.
|
||
|
|
|
||
|
|
6. Added ButtonEnabled and CheckBoxEnabled functions.
|
||
|
|
|
||
|
|
7. Changed LB_SETSELECTION message to accept -1 to turn off
|
||
|
|
selections in the listbox.
|
||
|
|
|
||
|
|
8. Moved processing of ID_SEARCH, ID_SEARCHNEXT, ID_REPLACE, ID_CUT,
|
||
|
|
ID_COPY, ID_PASTE, ID_DELETETEXT, ID_UNDO, and ID_CLEAR to editbox.c,
|
||
|
|
relieving applications of these common processes.
|
||
|
|
|
||
|
|
9. Now allow marking blocks, cut, copy, paste, etc. on single line
|
||
|
|
editboxes.
|
||
|
|
|
||
|
|
10. Added SetProtect function.
|
||
|
|
|
||
|
|
11. The Window menu listed doc windows that were not visible.
|
||
|
|
|
||
|
|
12. Changed class identifiers to Class.
|
||
|
|
|
||
|
|
13. ClearWindow did not work properly for a window with a status bar
|
||
|
|
and menu bar and no title bar.
|
||
|
|
|
||
|
|
14. Added the void *wrapper field to the window structure to support
|
||
|
|
a C++ class wrapper around the D-Flat C function library.
|
||
|
|
|
||
|
|
15. Sizeable windows with borders now display a small token in the
|
||
|
|
lower right corner to indicate that they are sizeable.
|
||
