Subject: A Revised (slightly) Proposal
Precedence: bulk
In addition to keyboard short-cuts we need standardized panels (dialogs),
standard menu positions, and other such guidelines, like how a block
should be selected, how to select discontinous blocks, application data
linkage (no GEM app currently supports this I believe), and what happens
when you type and a block already exists. The only way to satify everyone
is to make a standard that allows user configuration. The NeXT guide specifies
that short-cuts can be changed. I submit the following based on 3 standards,
in order - Atari Compendium, NeXT Guidelines (an extension of apple), and
finally this list. You do NOT have to implement everything in here, and
the guideline also specfifies how to NOT use the guideline! Also, the
APP_DEFS.SYS file mentioned here and options such as the block=big-cursor
and other weirdness, or country-specific options and such should be
supplied in here. The user should be able to configure everything globally
and should be be able to configure each app separately if he/she so desires.
We also need to discuss mouse pointers and cursor types, and it is possible
that these would be in the APP_DEFS.SYS too!
Function Keys are app-dependant, normally used for macros or execution of
external programs. Possible are normal, shift, control, alt, shift/control,
shift/alt, but NOT any combination of with alt and control at once.
===========================================================================
The following is based on the NeXTStep User Interface Guidelines 3.2
Chapter 3: User Actions: The Keyboard and Mouse. It assumes that user
preferences are stored in the APP_DEFS.SYS file which is searched for
in the following directories, in order, "U:\etc", "C:\multitos", "C:\mint",
"C:\system", "C:\", and finally the current working directory. "A:"
should be substituted for "C:" if the user booted from floppy. Also, the
current working directory will be searched even if the file is already
found in another directory and these settings will over-ride settings
previously found.
Choosing Keyboard Alternatives
Initially, until the user specifies a different preference, applications
should follow the guidelines for keyboard alternatives described in this
section. Users can use the Preferences application to alter the keyboard
alternatives for every application at once. You're also encouraged to let
the user choose and change keyboard alternatives using your application's
Preferences panel.
Some sort of "Preferences" application should be generated by the gem-list.
To change the global preferences, run the app, and to change the preferences
of a specific application, pass that application's name on the command line.
This can be run from another GEM application, concurrently if your AES allows
it to provide a consistent interface for editing the APP-DEFS.SYS file.
A global usage "Install" application could also set paths and options in
this file as well as copy the files to the proper destination, make
directories, install icons in the desktop RSC file, and also de-install
all these options and icons and delete the proper files when needed.
By allowing the user to change keys globally he can conform best to the
application/standards that he uses most, so if he want to have ^U close
a window the user can change it himself (although he will have to find
a new key for underline!)
Code will also be provided (possibly a whole library) for parsing the file
and for utilizing the information contained within.
The guidelines place keyboard alternatives into three groups--reserved,
required, and recommended. These groups are listed in the tables that fol-
low along with the commands they perform and the menus where the commands
are located.
Note that "Command" is normally CONTROL, since ATARI has reserved some ALT
combinations and others are used to generate special keys. Terminal programs
should over-ride global settings in an application specific line so that
ALT is used as the Command key for that app. Shift is the up-arrow (ascii 1)
In menus, the caret "^" denotes CONTROL and the window closer should be used
for ALT, and an equivalence character (ascii 240) in a boxchar object should
be used for drop-down lists. The use of the word "panel" refers to a
a standardized dialog which the gem-list should provide code and RSCs for.
The right arrow shows a cascading menu, the delete character (the delta) is
for the iconify/miniturize gadget and buttons that show >> expand the dialog
while << shortens a dialog (for advanced and novice user options).
Any function below is assumed to work on upon the currently selected object,
and if no object is selected, it is global. So HIDE, is hide the currently
selected object, or hide the application. Show Info gives information about
the object, or about the application.
Reserved Keyboard Alternatives
Reserved keyboard alternatives must be used for the commands that follow,
and cannot be used for any others. If your application implements the
functionality that a command represents, it must provide both the command
and the keyboard alternative.
For example, if your application opens files, it must have an Open command
with Command-o as the keyboard alternative. If your application doesn't
allow the user to open files, it won't have an Open command and must not
use Command-o as a keyboard alternative.
