Then, we use the delete method to delete all items in the TreeView by passing the get_children method to the delete method as an argument. In this example, we first create a TreeView and add some items to it. Tree_view.insert('parent1', 'end', text='Child 2')

Tree_view.insert('parent1', 'end', text='Child 1') Tree_view.insert('', 'end', text='Parent 1')

Here's an example code snippet that demonstrates how to delete all items in a TreeView: # Create a TreeView

The delete method takes an iterable of items to delete as an argument. To delete all items in a TreeView in Python, you can use the delete method. * The mainloop() method starts the main loop, which keeps the window open and running until the user closes it. The command argument specifies the function that is called when the button is clicked. * The button variable is a reference to the button widget. The text argument specifies the text for the item. The insert() method is used to add items to the treeview. * The tree variable is a reference to the treeview widget. Then, it loops through the items and deletes them using the delete() method. * The delete_all_items() function gets all the items in the treeview using the get_children() method. Here is a more detailed explanation of the code: When the 'Delete All Items' button is clicked, all the items in the treeview are deleted. The output of this code is a window with a treeview that contains three items. # Create a button to delete all the itemsīutton = Button(window, text='Delete All Items', command=delete_all_items) Sure, here is an in-depth solution for deleting all items in a treeview in Python, with proper code examples and outputs: python The output of this code will be an empty TreeView widget. Then, we use a for loop to iterate over all the items in the TreeView and delete them using the delete method. In this code, we first create a TreeView widget and add some items to it. Treeview.insert('', 'end', text='Item 3') Treeview.insert('', 'end', text='Item 2') Treeview.insert('', 'end', text='Item 1') Here is an example code that deletes all items in a TreeView: import tkinter as tk This method takes two arguments: the first argument is the ID of the item to delete, and the second argument is the index of the item to delete. To delete all items in a TreeView in Python, you can use the delete method of the TreeView widget. Programming Language: Python, Popularity : 5/10 #Clear the treeview list itemsĪfter invoking the function, it will clear the whole treeview list items from the window.Īfter clearing the treeview, it will display an empty treeview list.Answered on: Sunday 04 June, 2023 / Duration: 18 min read Now, adding the following code before the mainloop will remove and clear the whole treeview list. Running the above code will display a window that contains a treeview hierarchy of Programming languages categorized for FrontEnd and Backend. Treeview.insert('i3', 'end', 'RUST', text ='Python') Treeview.insert('i2', 'end', 'Python', text ='JavaScript') Treeview.insert('i2', 'end', 'HTML', text ='RUBY') Ttk.Label(win, text ='Treeview(hierarchical)').pack() Win.title('Application to represent the Programming Languages ')

In this example, we will create a treeview for the Programming Language and will clear the list of items using delete() operation.

The function can be invoked while iterating over the treeview items. Let us suppose we have created a list of items using treeview widget and we want to clear the entire treeview, then we can use the delete() function.

It generally looks like the file explorer in Windows or Mac OS. Tkinter Treeview widgets are used to display the hierarchy of the items in the form of a list.
