Tkinter Listbox widget is generally used to create a list of items. It can store a list of numbers, characters and support many features like selecting and editing the list items.
To edit the Listbox items, we have to first select the item in a loop using listbox.curselection() function and insert a new item after deleting the previous item in the listbox. To insert a new item in the listbox, you can use listbox.insert(**items) function.
In this example, we will create a list of items in the listbox widget and a button will be used for editing the selected item in the list.
# Import the required libraries from tkinter import * from tkinter import ttk # Create an instance of tkinter frame or window win = Tk() # Set the size of the window win.geometry("700x350") # Create a Listbox widget lb = Listbox(win, width=100, height=10, background="purple2", foreground="white", font=('Times 13'), selectbackground="black") lb.pack() # Select the list item and delete the item first # Once the list item is deleted, # we can insert a new item in the listbox def edit(): for item in lb.curselection(): lb.delete(item) lb.insert("end", "foo") # Add items in the Listbox lb.insert("end", "item1", "item2", "item3", "item4", "item5") # Add a Button To Edit and Delete the Listbox Item ttk.Button(win, text="Edit", command=edit).pack() win.mainloop()
Running the above code will allow you to select and edit the list items.
You can configure the list of items by clicking the "Edit" button.
