How to set the tab order in a Tkinter application?
The Tab order in any application decides which element of the application have to set focus. In a Tkinter application, it constantly looks for the next widget that needs to be focused on. To set the tab order in the application, we can define a function and pick all the widgets and use lift() method. It will allow the function to set the focus on a particular widget programmatically.
Example
#Import the required libraries from tkinter import * #Create an instance of Tkinter Frame win = Tk() #Set the geometry of Tkinter Frame win.geometry("700x350") #Add entry widgets e1 = Entry(win, width= 35, bg= '#ac12ac', fg= 'white') e1.pack(pady=10) e2 = Entry(win, width= 35) e2.pack(pady=10) e3 = Entry(win, width= 35, bg= '#aa23dd',fg= 'white') e3.pack(pady=10) #Change the tab order def change_tab(): widgets = [e3,e2,e1] for widget in widgets: widget.lift() #Create a button to change the tab order Button(win, text="Change Order", font=('Helvetica 11'), command= change_tab).pack() win.mainloop()
Output
Running the above code will display a window with a set of Entry widgets and a button to change the Tab order of each widget.
