Hey. I am making a tkinter application and I an dispalying multiple rectangles and I want to colour them based on the name I give to the function
Code:
So I initially create the rectangles by executing function picking_gui(), then want to change to color of certain rectangles based on the input I give. For example I give string "device1" as an arugment for update_rectangle_color() function and It would update device1 rectangle. However, it does not work because I am passing a string as an argument and it does not think that its a variable. What are my options to solve this?
I want to call function like that:
update_rectangle_color("device1"):
Instead, it expects me to call function like that:
update_rectangle_color(device1)
Code:
Code:
def picking_gui():
global device1,device2,device3,device4,device5,device6,device7,device8,device9,device10,device11,device12,device13,device14,device15,device16,device17,device18,device19,device20
#global canvas_tk
device1 = canvas_tk.create_rectangle(30,400,80,450,fill='red')
device2 = canvas_tk.create_rectangle(120,400,170,450,fill='red')
device3 = canvas_tk.create_rectangle(220,400,270,450,fill='red')
device4 = canvas_tk.create_rectangle(320,400,370,450,fill='red')
device5 = canvas_tk.create_rectangle(420,400,470,450,fill='red')
device6 = canvas_tk.create_rectangle(520,400,570,450,fill='red')
device7 = canvas_tk.create_rectangle(620,400,670,450,fill='red')

print("updating rectangle colour=",device_name)
canvas_tk.itemconfig(str(device_name),fill="green")
