How to know if a given widget is focussed?

[BhagyaJyoti22006]

import customtkinter as tk

def check_focus(widget):
    widget.focus_set()
    root.update()
    focused_widget = root.focus_get()
    if focused_widget.winfo_name() == widget.winfo_name():
        print(f"The widget is focused.")
    else:
        print(f"The widget is not focused.")

root = tk.CTk()

entry = tk.CTkEntry(root)
button = tk.CTkButton(root, text="Check Focus", command=lambda: check_focus(entry))

entry.pack(padx=10, pady=10)
button.pack(pady=10)

root.mainloop()`

Even if i have focussed on entry widget, i get false.
I printed them when I have widget selected and got output:
focussud- .!ctkentry.!entry
widget- .!ctkentry

They both are same still printing different values. How, help?

They are related, but not the same widget.

CTkEntry is a CustomTkinter wrapper widget. The actual editable Tk entry inside it is a child widget, which is why focus_get() returns something like:

.!ctkentry.!entry

while the outer CustomTkinter widget is:

.!ctkentry

So this comparison fails:

focused_widget.winfo_name() == widget.winfo_name()

because you are comparing the inner Tk entry with the outer CTk wrapper.

For a CTkEntry, you can check the internal entry widget:

def check_focus(widget):
    widget.focus_set()
    root.update()
    focused_widget = root.focus_get()

    if focused_widget == widget._entry:
        print("The widget is focused.")
    else:
        print("The widget is not focused.")

_entry is a private implementation detail, so for application logic I would usually track focus with events instead:

focus_state = {"entry": False}

def on_focus_in(event):
    focus_state["entry"] = True

def on_focus_out(event):
    focus_state["entry"] = False

entry.bind("<FocusIn>", on_focus_in)
entry.bind("<FocusOut>", on_focus_out)

Then read focus_state["entry"] whenever you need it. Also keep in mind that clicking a button can move focus away from the entry, so event tracking is often more reliable than checking focus only inside the button command.
