Window Logic System - Documentation


Method of Operation______________________________________________
Method of Operation
Method of Operation
Method of Operation

ProWindows *LITE* is more than just a windowing module, in a way,
it is more like a special operating system. Both of these
packages are based upon the PRO-WLS (Professional Window Logic
PRO-WLS
PRO-WLS
PRO-WLS
System) unit. The PRO-WLS unit manages every subroutine used to
PRO-WLS
PRO-WLS
PRO-WLS
create, print to, clear, and finally, remove a window.

When you call the PopWindow subroutine, many important procedures
PopWindow
PopWindow
PopWindow
take place. First, PRO-WLS saves the portion of the current
PRO-WLS
PRO-WLS
PRO-WLS
screen you are about to place the window over. Then, using a
proprietary compression algorithm, the old screen is squeezed to
sometimes less that 80% it's original size. This is intended to
save you plenty of memory space. Also, your compressed screen is
stored in 'far' memory so you will save that valuable 'string
space'.

After compression, every parameter you gave PopWindow is placed
PopWindow
PopWindow
PopWindow
onto the window stack. The window stack is used to tell the other
ProWindows subroutines where and how they can place text within
the intended screen. In addition, it also holds vital information
as to how your old screen is to be decompressed and re-displayed
when you call the RemoveWindow subroutine. This version comes
RemoveWindow
RemoveWindow
RemoveWindow
with a default stack that can hold up to 30. You may modify this
by adjusting a few variables in the include file.

All this happens in about 1/10th of a second.

When you call the RemoveWindow subroutine, the exact opposite
RemoveWindow
RemoveWindow
RemoveWindow
happens. The PRO-WLS unit locates your old screen, decompresses
PRO-WLS
PRO-WLS
PRO-WLS
it, and places it back on your current screen, and at the correct
location too.

Nothing could be easier.

ERROR HANDLING___________________________________________________
ERROR HANDLING
ERROR HANDLING
ERROR HANDLING

ProWindows *LITE*, by design, is a very delicate system. It's
error handling procedures were designed so that in the event of a
major error, the program terminates, rather than possibly lock up
your entire system. As you may realize, this forces you to write
programs with special attention to accuracy.

When a fatal occurs, the following error messages are displayed:

"No window to remove." occurs if you try to delete an nonexistent
window.

"Too many windows." will be displayed if you attempt to create
more windows than you have subscripted.

"Not a supported video mode.". ProWindows *PLUS* - Version 1.00
supports only the following modes:

BW80 80 x 25 b/w text
CO80 80 x 25 16 color text
MONO 80 x 25 mono text

All other video modes will cause an error. Future versions may
support additional video modes.

"Invalid copyright.". The entire "ProWindows" line of products is
copyrighted material. The only time you will ever get this error
is if you have altered the internal copyright notices. This, by
the way, is a very serious crime. Please do not ever degrade
yourself, and risk criminal prosecution, by modifying the
copyright. Violators will be turned over to the FBI without
warning.

You must include the files PROWINDB.INC with programs that

placing the following command on the very first line of the main

Failure to implement this may cause your system to instantly lock.

an appropriate DECLARE SUB or DECLARE FUNCTION statement is
DECLARE SUB DECLARE FUNCTION

DECLARE SUB DECLARE FUNCTION
automatically generated and placed at the head of the program
source code. This statement serves two distinct purposes, one as
a matter of safety and another of pure convenience .

FOR YOUR SAFETY, every time you call a declared function,

QuickBASIC checks that every passed parameter is of the correct
type. Attempting to pass a STRING variable to a routine that
requests an INTEGER could be disastrous if unchecked. If each
routine is DECLARE'd, your errors will be caught before the damage
is done.

FOR YOUR CONVENIENCE, all DECLARE'd routines can be called without

the need of using the CALL statement. In addition, you can get

rid of all those parentheses too. As a few examples:

The ProWindows Subroutine:

CALL PopWindow( 5, 5, 15, 70, attr(7, 0), 1, 1, 0)
CALL TitleWindow( 5, "This is a Title")
CALL RemoveWindow

become:

PopWindow 5, 5, 15, 70, attr(7, 0), 1, 1, 0
TitleWindow 5, "This is a Title"
RemoveWindow


Simple nostalgic reasoning force me to keep the parentheses and
CALL's on all routines that require arguments. For those without
arguments, I don't prefix it with a CALL.

As for you, do what is comfortable for you. Just do it
consistently.
