- ** Revision History in reverse order:
- **
- ** The following changes were incorporated in the 06.04.87 release:
- **
- ** 06.03.87 - Support for BORLAND Turbo C!!
- **
- ** The following changes were incorporated in the 05.12.87 release:
- **
- ** 05.12.87 - wns_text was incorrectly compensating for single line
- ** borderless windows (Attachmate follow up).
- **
- ** 05.04.87 - EXPLODING windows are now supported!! Simply add 800 to
- ** the video page when calling wn_open()!
- **
- ** - Calls of the form wn_insrow(wn,0) and wn_delrow(wn,0)
- ** caused the border to be klobbered. wn_insrow() and
- ** wn_delrow() were taught about borders.
- **
- ** 03.31.87 - wn_printf [wns_wtext()] was incorrectly displaying graphics
- ** characters. Thanks to Mark MacGee for reporting the problem.
- **
- ** 03.23.87 - Attachmate reported that wn_gets was doing funny things
- ** on single line bordered windows on PCs and PC clones but
- ** was fine on ATs and AT clones! It would appear that the
- ** PC/PC_CLONE BIOS can not deal with scrolling single line
- ** windows. wn_delrow() was taught to erase single line
- ** windows and avoid using the BIOS for this special case.
- **
- ** 03.19.87 - Argh!! Datalight elected to use M_I86 as a predefined
- ** equate. References to M_I86 were changed to
- ** MSCV3 | MSCV4. (Datalight 3.XX)
- **
- ** The following changes were incorporated in the 03.15.87 release:
- **
- ** 03.01.87 - wn_activate was incorrectly computing the coordinates of
- ** unbordered windows. Thanks to Peter Fletcher for reporting
- ** the problem and supplying a solution.
- **
- ** 01.22.87 - wn_dborder() was using the wrong attribute (wn-style,
- ** instead of wn->bstyle). Thanks to Peter Partch for
- ** reporting the problem and supplying a solution.
- **
- ** 01.06.87 - wn_activate was not walking through the current linked
- ** list of windows. In rare cases this would cause two
- ** windows to be considered non-overlapping when in fact
- ** they were. Thanks to Robert Klotz for reporting the
- ** problem.
- **
- ** The following changes were incorporated in the 01.01.87 release:
- **
- ** 12.19.86 - Removed a needless call to wn_err(wn,"wn_printf") in
- ** wn_title().
- **
- ** 12.16.86 - Improved centering logic for window titles.
- ** Thanks to Steve Liberty for suggesting the change.
- **
- ** 12.14.86 - Incorporated compiler specific equates in windows.h.
- **
- ** 12.13.86 - wns_mtype() returns 0 for mode 3, 2 for mode 0 or 2,
- ** and 7 for mode 7. (Internal Use - This change allowed
- ** for the prevention of blue on black characters when
- ** the video mode is 2 and a color monitor is in use.
- ** (wns_fixc & wns_mtype).
- **
- ** - BASIC support for Mark Williams "Lets C".
- **
- ** - Tightend free() checks in wn_activate, wn_close, and
- ** wn_restore.
- **
- ** 12.12.86 - wn_puts() was not adding the original physical cursor
- ** location to the logical cursor location.
- ** Thanks to Marek Glowacki for reporting the problem.
- **
- ** 12.10.86 - Allow v_locate() to position the cursor slightly off
- ** the screen. Previous limit was (24,79) current limit
- ** is (25,80) which is just beyond the edge of the screen.
- ** This was done to insure that hidden cursors remain out
- ** of view.
- **
- ** - Improved cursor handling when wn_dmaflg = FALSE.
- **
- ** 12.09.86 - Taught wn_activate to honor cursor position of window
- ** being activated. This will insure the cursor is always
- ** in the right logical and physical position.
- ** More cosmetic enhancement than logic error correction.
- **
- ** The following changes were incorporated in the 12.01.86 release:
- **
- ** 11.28.86 - Reverse video attribute was not being set correctly
- ** on MGAs - corrected.
- **
- ** 11.19.86 - wn_dborder was incorrectly computing the row offset.
- ** Thanks to Steve Thatcher for reporting the problem.
- **
- ** 11.16.86 - Added ".smeth" member to window control block. This
- ** member defines the scrolling method to be used in
- ** the window. It can be set to BIOS or DMAS, the default
- ** is DMAS.
- **
- ** - All routines that reference wn_activate will return
- ** NULL if the window could not be activated. This is
- ** usually due to a lack of free memory.
- **
- ** The following changes were incorporated in the 11.14.86 release:
- **
- ** 11.13.86 - Closing windows in random order when exiting "sometimes"
- ** produced null pointer assignment error messages or
- ** incorrect screen images - corrected.
- **
- ** - wn_natrib() was not storing the newly defined window
- ** attribute in the window control block - corrected.
- **
- ** 11.09.86 - Support for Datalight C added.
- **
- ** 11.02.86 - v_border() added. Allows color of border area to be
- ** set on CGAs with color monitors.
- **
- ** 11.01.86 - wn_fixcsr was not adding the original physical cursor
- ** location to the logical cursor location.
- ** Thanks to Bill Harts for reporting the problem.
- **
- ** - wn_puts was computing the virtual cursor location
- ** incorrectly. Thanks to Eric Lundstrom!
- **
- ** - Logic to dectect null strings was incorporated into
- ** _vidblt. This will prevent 64k worth of trash from
- ** being blitted to the video ram.
- **
- ** 10.30.86 - All references to MSC in "windows.h" were changed
- ** to M_I86. This forces "windows.fns" to be included
- ** under Microsoft C. This change was also applied to
- ** "windows.c".
- **
- ** 10.26.86 - Full float, long, etc. support for wn_printf in
- ** all Lattice versions. Microsoft 3.XX is the only
- ** one in the dark ages.
- **
- ** 10.23.86 - Tip of the hat to Russ Thackson for the improved
- ** overlaping window detection technique incorporated
- ** in wn_activate().
- **
- ** The following changes were incorporated in the 10.22.86 release:
- **
- ** 10.22.86 - wn_activate() was causing unnecessary window
- ** thrashing on non-overlapping windows. Corrected.
- **
- ** The following changes were incorporated in the 10.10.86 release:
- **
- ** 09.27.86 - Tiled windows are now supported! wn_activate() added.
- **
- ** - wn_gets() was not calling wns_err - corrected. This
- ** was not a bug, just continued support for wild pointer
- ** checks.
- **
- ** 09.25.86 - New logic for vidblt(). Fast mode now works on color
- ** without causing snow or flicker!! Video updates now
- ** occur at the fastest possible speed! The effect of
- ** wn_sbit now conforms exactly to the description in the
- ** manual.
- **
- ** - wn_printf (CI86) now has full float support. Thanks
- ** to Rob Sullivan for reporting the CI86 problem. Lattice
- ** and MSC Version 3.0 are the only hold outs for full
- ** wn_print support. MSC Version 3.0 support will never
- ** be incorporated. If you are using MSC Version 3.00
- ** you will have to upgrade to Version 4.XX. The price
- ** of the update is well worth it. Version 4.00 is a
- ** work of art! Lattice support will be delayed until
- ** Lattice gets around to supporting vsprintf() as
- ** defined by the evolving ANSI standard.
- **
- ** 09.17.86 - seperate modules to decrease memory overhead.
- **
- ** - link list support (wn_open,wn_close,WINDOWPTR struct)
- ** This is the ground work for tiled window support.
- **
- ** 09.02.86 - use registers in wns_savres() for speed (MSC).
- **
- ** The following changes were incorporated in the 08.30.86 release:
- **
- ** 08.28.86 - wn_gets was delclared as (char *) but returning
- ** (void). Corrected to return (char *).
- **
- ** 08.27.86 - wns_wtext() was not correctly handling borderless
- ** windows. Corrected.
- **
- ** - wn_printf() was not correctly handing cases such as:
- ** wn_printf(wn,"%s %d %f %d\n", "text", 2, 2.2, 5);
- ** The window boss now supports a complete implementation
- ** of printf formatting under Microsoft C Version 4.00.
- ** All other compilers and versions support an INTEGER only
- ** wn_printf. This will be corrected in a future release.
- **
- ** 08.16.86 - Added wn_gets(). Get string in window with validation.
- **
- ** The following chages were incorporated in the 06.02.86 release.
- **
- ** 06.02.86 - v_smode was using bh instead of ah. Corrected.
- ** Thanks to Rob Rainwater!!
- **
- ** 05.26.86 - Added wn_natrib. Set new window attribute NOW!
- **
- ** 05.25.86 - Corrected a potential problem with a couple of the routies
- ** in MSVLIB.ASM. Registers SI & DI were being used but not
- ** being saved. This "may" cause spurious probles with "C"
- ** programs that use register variables. Microsoft C 3.0 only.
- **
- ** - wn_titla was not calling wns_fixc. Corrected.
- **
- ** 05.24.86 - Added wn_titla. write window title with attributes.
- **
- ** 05.10.86 - wn_putsa was not calling wns_fixc. This caused problems
- ** when CGA was in mode bw80 but putsa was called with a
- ** valid color atrib.
- **
- ** The following changes were incororated in the 05.08.86 release.
- **
- ** 05.07.86 - Additions for Microsoft "C" version 3.0
- **
- ** 05.05.86 - wn_printf fix for lattice version 3.0.
- **
- ** 04.25.86 - Added support for handling backspace, delete, & BELL
- ** characters correctly (wns_wtext).
- **
- ** Incorporated v_wtty in vlib.asm.
- **
- ** Initial Release..
- **
- ** 01.24.86 - Initial release with a bit of a false start thanks to
- ** Microsoft's Lib.
