SCENE BUILDER
Copyright (C) 1993 by Jerry Rivers, All Rights Reserved
BASIC OPERATION:
Most functions are selected from the menu using the LEFT mouse button.
These include drawing tools (e.g., lines), styles (e.g., dashed lines),
text, disk I/O (e.g., open), display (e.g., zoom), snap grid, etc.
Many functions also have a keyboard "shortcut key".
Drawing colors and object "fill" patterns are selected with the LEFT
mouse button. Fill colors are selected with the RIGHT mouse button.
Current draw and fill colors are shown in the menu grid to the left of
the color squares. The outside color is "draw"; the inside is "fill".
Fills are turned off and on by pressing the LEFT mouse button inside the
"fill" square. If fill mode is "on", the drawing tools in the left
column of the menu will be filled with white; if fill is "off", they
will be filled with light gray.
MOUSE CURSORS:
The appearance of the graphics mouse cursor changes according to the
function being performed (e.g., the line draw cursor is a "+" cross with
a "/" line underneath, flood fill is a small paint roller). A full
description is included later in the help file.
MENU LAYOUT:
Menu items are selected with the mouse or keyboard from a on-screen
grid. The menu can be moved anywhere on the screen if the LEFT mouse
button is held down while the 4-arrow mouse cursor is in the menu top.
Drawing tools, line styles, display controls, colors, fills, and snap
grid controls are illustrated on the next two help screens. Each
function shows the corresponding keyboard shortcut key, if applicable.

SCENE BUILDER GENERAL INFORMATION
Each drawing tool works similarly. After selecting a tool, the menu will
disappear and a tool-specific mouse cursor will appear.
Move the cursor to the spot you want to begin drawing the object. To
begin drawing, press the LEFT mouse button. Dragging the mouse draws
using "rubber band" lines.
If "snap" is on, the cursor will automatically move to the nearest grid
boundary, whether the snap grid is displayed or not.
Release mouse button to stop drawing. Continue to draw until you press
the RIGHT mouse button, which signals you want to quit using that tool.
During the drawing process, you may want to move an object from the
origin picked with the LEFT mouse button. Press the "Alt" key (while
still holding the LEFT mouse button down) to move the entire object to a
new location. A "hand" mouse cursor will appear to show "move" mode.
Immediately after releasing the LEFT mouse button, you can construct any
number of duplicate objects by holding the "Ctrl" key down and moving
the mouse. Like Alt, a "hand" cursor will show "move or duplicate" mode.
Fully enclosed objects such as rectangles, polygons, and circles can be
"filled" with a solid color or with a colored pattern. SceneBuilder
supports seven standard Pascal fill patterns. Enclosed objects can be
filled at the time of creation (if "fill" mode is "on", shown by the
drawing tools filled with white) or can later using the flood-fill tool.
The SHIFT key can be used to force lines to be horizontal, vertical or
45 degrees. Rectangles can be forced into squares using the SHIFT key.
You can turn on a "snap" grid of any specified size to help line-up your
drawing objects. The snap grid may be displayed as a series of dots.
When a scene is zoomed in, the snap grid is automatically set to the
zoom scale factor.
DETAILED MENU ITEM DESCRIPTIONS
UNDO LAST OPERATION: Shortcut Key = "U"
If you make a mistake or don't like how the last object(s) look, select
Undo from the menu grid. Your scene will be returned to the same
appearance as before.
You can NOT "undo" an "undo".
STRAIGHT LINES: Shortcut Key = "L"
Mouse cursor: Large "+" with a "/" line
Pick the starting point of the line with the LEFT mouse button. Drag the
end-point until the line is where you want it. SHIFT constrains lines
to horizontal, vertical, or 45-degrees. The Alt key may be used to move
a partially completed line.
The Ctrl key may be used to duplicate identical lines.
Press the RIGHT mouse button again when you are finished.
GROUPED LINES (END-TO-END): Shortcut Key = "G"
Mouse cursor: Large "+" with a "/" line
Pick the starting point of a line group with the LEFT mouse button. Drag
the end-point until the line is where you want it. SHIFT constrains
lines to horizontal, vertical, or 45-degrees. The Alt key may be used
to move a partially completed line segment.
Continue to drag line segments unti
