THE USER INTERFACE
FILE SELECTOR
-------------
The File Selector will appear when SAVE DATA, LOAD DATA, LOAD
OBJECT or LOAD BORDER is selected from the FILE menu at the top of
the VIEW window. The first files in the current directory will be
displayed. The arrows on the right of the file selector will scroll
up or down through the files in the current directory if there are
more files than can be shown in the space available.
In general, the File Selector can be considered a menu tool that
allow you to move around your disk drives and hard drive, so you
may load and save data in the areas of the disks you choose.
Some simple things to remember:
* You can point to any drive at the top of the File Selector box
(A:, B:, C:, etc.) to retrieve or save data to your drive.
* Clicking on the "previous directory" box - the rectangular box
the left of the file window - will take you back to the
previous directory (the directory above the current
directory).
* The PATH name at the bottom of the File Selector window shows
the current directory that you are in.
* It is recommended that you save files in the proper locations.
For example, it is best to save DATA and OBJECT files in the
DATA directory, border information in the BORDER directory,
etc.
Select the required file by clicking on the filename with the mouse
button and the selected filename will appear to the right of the
FILE heading. Alternately you can click to the right of the FILE
heading (bottom area of menu) and type in the file name using the
keyboard, pressing ENTER when satisfied.
To load or save the selected file click on OK. Just above the FILE
name is the PATH which shows which drive is currently being used,
along with the current position within directories. To change the
path, click on the rectangular box in the upper left of the menu.
Floppy users can save to a formatted floppy disc if the current
disc is full.
ALERT BOXES
-----------
During environment creation there will be instances where something
you have attempted to do will be either not possible or
irrevocable. In these instances an ALERT BOX will appear with
information about the function requested. If the function is not
possible the alert box will simply inform you of this and then wait
for confirmation before canceling the function. If the function is
irrevocable, i.e. CLEAR ALL, the alert box will give you the chance
to reconsider the action and continue with or stop the function.
ALERT BOXES are also used to inform you that an otherwise invisible
function has executed correctly. In this case the alert box will
simply require input from you to confirm the message has been
received.
DIALOG BOXES
------------
There are various parts of the environment creation which will
require input from you to set parameters relating to the current
function. These parameters will usually be set within a DIALOG BOX
DIALOG BOXES are simply windows which will open at a set place
(usually the center of the screen). These are similar to ALERT
BOXES but with the added ability of user interaction. Interaction
takes place in one of two ways, buttons or text/numerical input.
Buttons can be one of three types. TOGGLE buttons which toggle
between selected and unselected when activated. RADIO buttons which
are part of a group of at least two buttons, when one radio button
in a group is selected all other members of the group are
unselected. FUNCTION buttons which do a specific task directly if.
OK or CANCEL.
Text boxes may be edited by first clicking over the text to be
edited and if the text may be edited it will become inversed and a
cursor will be displayed at the first character. You may then type
your text in using the normal functions. DEL deletes a character
under the cursor, BACKSPACE deletes the character before the cursor
and other keys enter the desired character over the current content
of the cursor position.
Some text lines will restrict you to either NUMERICAL or ALPHA
character only, to end editing of a particular text item, simply
press the RETURN key whereupon the text will return to normal print
and any restrictions on numerical values will be applied, ie. if
you were to type in the number 9000 for an object position, as the
maximum area coordinate is 8192, it will automatically be
restricted to 8192 on pressing RETURN.
Note that while editing a text or numerical item it is impossible
to edit the DIALOG BOX or edit any other fields until you have
finished editing the current text item by pressing RETURN.
TEXT EDITING
------------
Text editing is used to change commands and usually takes place in
the lower half of the screen directly below the VIEW window after
selecting any of the icons which bring up the text editing window.
The text editing window will come up if you are editing either
conditions or animations. An inverse square will indicate your
current cursor position. This position may be changed by either the
keyboard or the control icons
