Property Getting and Setting

Property Getting

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

Property Setting

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)

Examples

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()
