Property Getting and Setting
object.property_name
To get any property from an Easy Draw object, simply use the variable name of storing the object dot the name of the property.
Example: Getting the
radius
property from a Regular Polygon object named pentagon
pentagon.radius
Example: Getting the
color
property from a Text object named title
title.color
object.set_property(property_name = new_value)
To set a property to a new value, you must call the
.set_property()
method on the object you want to change, identifying the property you want to change and its new value.Example: Changing the
text
property of a Text object named title
title.set_property(text = "Player 1 has selected a character...")
Example: Changing the
width
property of a Rectangle object named box
box.set_property(width = 200)
In this example we will create a square with a random color and an octagon with default color,
"black"
. Whenever the octagon is clicked, its color will change to the square's color.To do this, we need to get the
color
property of the square and set the color
property of the octagon.Get the square's color property --
square.color
Set the octagon's property --
octagon.set_property()
import easy_draw
import random
easy_draw.load_canvas()
square = easy_draw.Rectangle(
xy = (100, 100),
width = 200,
height = 200,
color = random.choice(["blue", "red", "yellow", "green", "orange", "purple"])
)
octagon = easy_draw.RegPolygon(
center_xy=(400,400),
radius=100,
nsides=8
)
def click_octagon(event):
global square
global octagon
octagon.set_property(color = square.color)
square.event_setup("<Button-1>", click_octagon)
easy_draw.end()
In this example, we create a growing circle by increasing the circle's radius by 10 each time it is clicked.
Notice how the Circle object's
radius
property is set to the current cir.radius
plus 10. import easy_draw
easy_draw.load_canvas()
cir = easy_draw.Circle(
center_xy = (300, 300),
radius = 20
)
def click_circle(event):
global cir
cir.set_property(radius = cir.radius + 10)
cir.event_setup("<Button-1>", click_circle)
easy_draw.end()
