It’s a simple object oriented graphics library.
The library is designed to make it very easy for novice programmers to experiment
with computer graphics in an object oriented fashion. It is written by John Zelle for
use with the book "Python Programming: An Introduction to Computer Science"
(Franklin, Beedle & Associates).
The GraphWin class implements a window where drawing can be done, and
various graphics objects are provided that can be drawn into a GraphWin.
The library provides the following graphical objects:
Point
Line
Circle
Oval
Rectangle
Polygon
Text
Entry (for text-based input)
Image

# update drawing to graphics window
getHeight()
getWidth()
getMouse() # wait for mouse click and return Point obj representing click
location
setBackground(color)
# color could be something like "red"
setCoords(xll, yll, xur, yur) # Sets the coordinate system of the window so
that the lower left corner is at (xll, yll) and the upper right corner is at (xur, yur)
Point(x, y)
clone()
# create a new Point object that is an exact copy of this one
getX()
# the int value of the Point's x-coordinate
getY()
# the int value of the Point's y-coordinate
draw(graphwin):
# Draw the object in graphwin, which should be a
GraphWin object. A GraphicsObject may only be drawn into one window.
move(dx, dy):
# move object dx units in x and dy units in y direction
setFill(color):
# Set interior color to color
setOutline(color):
# Set outline color to color

undraw():
# Undraw the object (i.e. hide it).
Line(p1, p2)
# p1 and p2 are the end Points of the line
Rectangle( p1, p2) # p1 and p2 are points for upper left lower rt
Circle(p1, radius)
# p1 is a Point at the center of the circle, radius is an int
Oval(p1, p2)
# p1 and p2 are Points of opposite corners of
bounding rectangle
Polygon()
# ex. triangle: Polygon ([Point(10,20), Point(30,40),
Point(10,60)])
getPoints()
# return a list of Points in the polygon
text(p, text)
# p is center point and text is string
