I have a customtkinter (CTk) button widget that, when pressed, sends an encoded message to a client depending on the button's "text" value; in this case, if the button's text is "Off", it sends the message "On" and vice versa to the client.
import tkinter as tk
import traceback
import customtkinter as cust
import socket
from threading import Thread
from tkinter import messagebox
class GUI2(cust.CTk): #second window; not the root
def __init__(self):
super().__init__()
self.PORT = 5000
self.SERVER = socket.gethostbyname(socket.gethostname())
self.ADDRESS = (self.SERVER, self.PORT)
self.FORMAT = "utf-8"
self.clients = [] #list to store all client connections
self.server = socket.socket(socket.AF_INET,
socket.SOCK_STREAM)
self.server.bind(self.ADDRESS)
self.master2 = cust.CTkToplevel()
self.ecdpower = cust.CTkButton(self.master2, text = "Off", fg_color = "Black", text_color = "White", hover_color = "Silver", command = lambda: Thread(target = self.startstream).start())
self.ecdpower.grid(row = 0, column = 0) #button to send message to client connections
self.thread = Thread(target = self.startChat)
self.thread.start() #starts function to accept client connections
def startChat(self): #function to accept client connections
self.server.listen(30)
try:
while True:
self.conn, self.addr = self.server.accept()
self.clients.append(self.conn) #stores all client connections
except:
pass
def startstream(self):
try:
if not self.clients: #checks if list is empty
messagebox.showerror("No Connections!", "No clients connected to host!")
else:
for x in self.clients:
if self.ecdpower["text"] == "Off": #ecdpower button widget acts like a "power button"
self.ecdpower.configure(text = "On", fg_color = "Green")
x.send(("On").encode(self.FORMAT))
else:
self.ecdpower.configure(text = "Off", fg_color = "Red")
x.send(("Off").encode(self.FORMAT))
except:
print (traceback.format_exc())
Error is as follows:
Traceback (most recent call last):
File "f:\project\mainmenu.py", line 390, in startstream
File "F:\Program Files (x86)\Python\lib\tkinter\__init__.py", line 1681, in cget
return self.tk.call(self._w, 'cget', '-' + key)
_tkinter.TclError: unknown option "-text"
I have also tried if self.ecdpower.cget("text") == "Off: and tried other values like fg_color; both result in the same error. When I removed the if condition, the message sending works correctly so the only problem is how to verify the button "text" value.
Any help to fix this or possible other alternatives is greatly appreciated.
Per @jasonharper's comment above, CTkButton is
not actually a Tkinter Button at all (it's made from a Frame containing a Canvas and a Label), so the normal Tkinter attribute-getting functions don't apply.
Instead of using self.ecdpower["text"] or self.ecdpower.cget("text"): I should use
self.ecdpower.text
to get the CTKbutton's text value.
The same can be applied with fg_color; use self.ecdpower.fg_color to get the value.
