![]() lumn( 'email', width= 200, anchor=tk. lumn( 'last_name', width= 100, anchor=tk.W) It also set the anchor for the item in each column accordingly: lumn( 'first_name', width= 100, anchor=tk.W) The following example sets the width for the first name and last name column to 100 and the email to 200. column( size, width, anchor) Code language: CSS ( css ) To change the size of a column and anchor of the item, you can use the column() method of the Treeview object: tree. (selected_item) Code language: Python ( python ) Customizing columns To get the selected item, you use the selection() method of the Treeview object: def item_selected (self, event): for selected_item in (): Second, delete the selected item from the tree. Since the CSV files are going to get several hundred records long, the record list is bound to overflow the height of the application window, even. Clicking an item will delete it from the tree: import tkinter as tkĪpp.mainloop() Code language: Python ( python )įirst, bind the item selected event: tree.bind( '>', em_selected) Code language: Python ( python ) The following program shows a Treeview with some items. To delete an item from Treeview, you use the delete() method of the Treeview object. Tree.insert( '', 0, values=( 'Alice', 'Garcia', ' '))Īpp.mainloop() Code language: Python ( python ) Deleting items from a Treeview Create a frame for the top, a frame for the treeview, and a frame for the bottom section. Your UI clearly has three distinct sections, you should organize your GUI that way. Tree.insert( '', tk.END, values=( 'John', 'Doe', ' ')) The mistake you are making is that you're trying to put everything into one massive grid, but the code to populate that grid is scattered throughout your program. Tree = ttk.Treeview(self, columns=columns, show= 'headings') The following program illustrates how to add items to the Treeview: import tkinter as tk To add an item at the beginning of the list, you use zero ( 0) instead of tk.END constant: tree.insert( '', 0, values=contact) Code language: Python ( python ) The following example adds an item at the end of the item list: tree.insert( '', tk.END, values=contact) Code language: Python ( python ) If you wanted to change the font style substitute None with whichever font you wanted. ![]() font(None, 100) is a 'cheaty' way of increasing font size without having to change the font itself. To add an item (or a row) to a Treeview widget, you use the insert() method of the Treeview widget object. 'Treeview.Heading' is the name of the element for the column headings. Showinfo(title= 'Information', message= ','.join(record))Ĭode language: Python ( python ) Adding an item to the Treeview widget Tree.heading( 'last_name', text= 'Last Name')Ĭontacts.append(( f'first ', f'email add data to the treeview for contact in contacts:ĭef item_selected (self, event): for selected_item in (): Tree.heading( 'first_name', text= 'First Name') Tree = ttk.Treeview(root, columns=columns, show= 'headings') The following program shows how to use the Treeview widget to display tabular data: import tkinter as tkĬolumns = ( 'first_name', 'last_name', 'email') The items are organized in the form of a tree. ![]() Using Tkinter Treeview to display tabular data Docs » Treeview Edit on GitHub Treeview ¶ A treeview widget can display a hierarchy of items. The first row of the Treeview consists of headings that identify each column by a name. The remaining columns contain values of each row. Second, create the root window, set its title and size: root tk.Tk () root.title ( 'Treeview demo' ) root. tvttk.Treeview (f,show'tree') Step 3: Create a vertical scroll bar. The first column may contain text and an icon that indicates whether it can be expansible or not. Step 1: Create a Frame roottk.Tk () root.geometry ('320x240') ftk.Frame (root) Step 2: Create a Treeview. To create a Treeview widget, you use the ttk.Treeview class: tree = ttk.Treeview(container, **options) Code language: Python ( python )Ī Treeview widget holds a list of items. import tkinter as tk from tkinter.ttk import Treeview root tk.Tk() f1 tk.Frame(root) f2 tk.Frame(root) f1.grid(column0, row0, sticky's') f2.grid(column1, row0, sticky'n') root.rowconfigure(0, weight1) Treeview(f1).pack. Introduction to the Tkinter Treeview widgetĪ Treeview widget allows you to display data in both tabular and hierarchical structures. How can I make the treeview resize when I resize the window in height I tried to set sticky'sn', I tried to pack the treeview with fill'y', but nothing worked. Summary: in this tutorial, you’ll learn about the Tkinter Treeview widget and how to use it to display both tabular and hierarchical data. ![]()
