How to Check If A Widget Has Focus In Tkinter?

4 minutes read

You can check if a widget has focus in tkinter by using the focus_get() method. This method returns the widget that currently has focus. You can then compare this widget with the widget you are checking to see if it has focus or not. If the two widgets are the same, then the widget has focus. Otherwise, it does not have focus.


How to check for focus on a combobox widget in tkinter?

To check if a combobox widget in tkinter has focus, you can use the focus_get() method to determine the currently focused widget and compare it with the combobox widget. Here's an example code snippet:

 1
 2

import tkinter as tk
from tkinter import ttk

def check_focus():
    if combobox == root.focus_get():
        print("Combobox has focus")
    else:
        print("Combobox does not have focus")

root = tk.Tk()

combobox = ttk.Combobox(root, values=["Option 1", "Option 2", "Option 3"])
combobox.pack()

button = tk.Button(root, text="Check Focus", command=check_focus)
button.pack()

root.mainloop()


In this code, the check_focus() function checks if the combobox widget has focus by comparing it with the currently focused widget using root.focus_get(). When you run this code and click on the combobox widget, then click the "Check Focus" button, it will print "Combobox has focus" if the combobox widget has focus, and "Combobox does not have focus" otherwise.


How to determine if a tkinter widget is in focus?

You can determine if a tkinter widget is in focus by using the widget's focus_get() method. This method returns the widget that currently has the focus. If the widget you are interested in is the one that has the focus, it will be returned by calling focus_get().


Here is an example code snippet to determine if a tkinter widget is in focus:

import tkinter as tk

root = tk.Tk()

def check_focus(widget):
    if widget == root.focus_get():
        print("The widget is in focus")
    else:
        print("The widget is not in focus")

entry = tk.Entry(root)
entry.pack()

button = tk.Button(root, text="Click me", command=lambda: check_focus(entry))
button.pack()

root.mainloop()


In this example, we create a tkinter Entry widget and a Button widget. The Button widget's command is set to a lambda function that calls check_focus(entry). The check_focus function compares the widget passed to it as an argument with the widget returned by root.focus_get() to determine if the widget is in focus or not.


How to check for focus on a spinbox widget in tkinter?

To check for focus on a Spinbox widget in tkinter, you can use the focus_get() method to determine if the widget currently has focus. Here is an example code snippet:

import tkinter as tk

root = tk.Tk()

def check_focus():
    if spinbox.focus_get() == spinbox:
        print("Spinbox has focus")
    else:
        print("Spinbox does not have focus")

spinbox = tk.Spinbox(root, from_=0, to=10)
spinbox.pack()

button = tk.Button(root, text="Check Focus", command=check_focus)
button.pack()

root.mainloop()


In this example, we create a Spinbox widget and a Button widget in a tkinter window. The check_focus function is called when the button is clicked, and it checks if the Spinbox widget has focus using the focus_get() method. If the Spinbox has focus, it will print "Spinbox has focus"; otherwise, it will print "Spinbox does not have focus".


How to determine if a radiobutton widget has focus in tkinter?

You can determine if a radiobutton widget has focus in tkinter by checking the focus_get() method of the Tkinter module. This method returns the widget that currently has the focus in the application.


You can call the focus_get() method on the radiobutton widget in question and compare it to the radiobutton widget itself. If the focus_get() method returns the radiobutton widget, then it has focus.


Here is an example code snippet that demonstrates how to determine if a radiobutton widget has focus:

 1
 2
 3
 4
 5
 6

import tkinter as tk

def check_focus():
    if radiobutton.focus_get() == radiobutton:
        print("Radiobutton has focus")
    else:
        print("Radiobutton does not have focus")

root = tk.Tk()

radiobutton = tk.Radiobutton(root, text="Option 1")
radiobutton.pack()

button = tk.Button(root, text="Check Focus", command=check_focus)
button.pack()

root.mainloop()


In this example, when you run the application and click on the radiobutton widget, then click on the "Check Focus" button, it will check if the radiobutton widget has focus and print the appropriate message.


How to determine if a scale widget has focus in tkinter?

You can determine if a scale widget has focus by using the focus_get() method in tkinter. This method returns the widget that currently has focus in the application.

import tkinter as tk

def check_focus():
    if scale.focus_get() == scale:
        print("Scale widget has focus")
    else:
        print("Scale widget does not have focus")
        
root = tk.Tk()

scale = tk.Scale(root, from_=0, to=100)
scale.pack()

button = tk.Button(root, text="Check Focus", command=check_focus)
button.pack()

root.mainloop()


In this example, the check_focus function checks if the scale widget has focus when the "Check Focus" button is clicked. If the scale widget has focus, it will print "Scale widget has focus", otherwise it will print "Scale widget does not have focus".
