Let us assume that we want to check if a particular widget has a focused set or not. The only way to check the widget focus is to use the utility method focus_get(). It returns the object containing the widget’s information which is currently focused on, during the program’s execution. We will use the focus_get() method to find the active widget during our program’s execution.
In this example, we have created an Entry widget that will get its focus when we press the <Enter> key. The focus_get() method will return the current widget’s information which is active.
#Import the Tkinter library from tkinter import * #Create an instance of Tkinter frame win= Tk() #Define the geometry win.geometry("750x250") #Define Event handlers for different Operations def event_show(event): label.config(text="Hello World") e.focus_set() print("focus is:" ,e.focus_get) #Create a Label label= Label(win, text="Press Enter",font=('Helvetica 15 underline')) label.pack() #Create an entry widget e= Entry(win, width= 25) e.pack(pady=20) #Bind the function win.bind('<Return>',lambda event:event_show(event)) win.mainloop()
Running the above code will display a window that contains a button. When we press the <Enter> key, it will print the output containing the widget’s information which is currently focused on the window pane.
Now, when we press <Enter>, it will show the output in the shell as,
focus is : <bound method Misc.focus_get of <tkinter.Entry object .!entry >>
