If I go to get ctklabel via mouse events, using event.widget.configure(bg_color) shows that there is no such attribute

[maxwangwyf]

def label_hover(event, text):
bbox = event.widget.bbox("insert")
if bbox is None:
return
event.widget.configure(bg_color="#DDDDDD")
def reset(event):
event.widget.configure(bg_color='#FDFDFD')

event.widget.bind("<Leave>", reset)

@maxwangwyf You need to use .winfo_parent() to access the ctklabel class, as clicking on the ctklabel returns its internal subwidgets. But note that the returned value will be in string format, so you have to use root.nametowidget method in order to configure the ctklabel widget.

Example:

import customtkinter

root = customtkinter.CTk()

def get_widget(event):
    widget = root.nametowidget(event.widget.winfo_parent()) #get the clicked widget class
    widget.configure(bg_color="red")
    
root.bind("<1>", get_widget) # bind the mouse click

label = customtkinter.CTkLabel(root, text="This is a Label")
label.pack(padx=10, pady=10)

root.mainloop()
