#Tkinter treeview example python 3 how to

Tree.insert('', t.END, text = 'Electrical engineering', iid=2, open=False) Tree.insert('', t.END, text = 'Mechanical engineering', iid=1, open=False) Tree.insert('', t.END, text = 'Engineering', iid=0, open=False) Tree.heading('#0', text = 'Courses', anchor=t.W) Root_window.title('Hierarchical representation') Here is a program with an example of the Hierarchical representation we discussed above with courses in engineering: By configuring it, we set the table in the window.

Now, as we create a tabular representation, we specify the names of the columns in a tuple.įinally, we assigned headings to the columns, inserted data into them, and created a function to handle the event ( When clicked on a row in the table, it displays a message). Using ttk.Treeview(), we created a Table Tree view widget with the root_window and columns, and by specifying ' headings' to show, we are telling the function to show the header row in the table. We created a root window called root_window, gave it a name, and gave dimensions to it. id(row = 0, column = 0, sticky = 'nsew') #Treeview widget on the root windowįirst, we imported the Tkinter module, the ttk sub-module, and the needed features(show info). Showinfo(title = 'Data', message = ' '.join(str(record))) Tree.heading('Phone number', text = 'Phone number')ĭata.append((f'', f'Phone number')) #list of tuples Tree.heading('Name', text = 'Name of the person') Tree.heading('SNo', text = 'Serial Number') #Headings Tree = ttk.Treeview(root_window, columns = descriptions, show = 'headings') To use themed widgets, we need to use the ttk class of the tkinter module.ĭescriptions = ('SNo', 'Name', 'Phone number')

Tkinter has two types of widgets-classic and themed.

A Tree view scrollbar is a regular scrollbar using Tree view widgets.įirst, let us cover the foundation of Tree view widgets:įor creating a Tree view widget, we need to import the tkinter.ttk module.

Here is an example of Tree view hierarchical representation of data: A top node can have second-level and third-level nodes also. There can be any number of top-level nodes, and only if we click on the extension will the sub-nodes appear. Hierarchical widget: It is the representation of the data level-wise.Tree table widget: Displaying the structures data in tabular format in rows and columns where rows represent items/ entities and columns represent attributes of the items.There can be two types of Tree view widgets in Tkinter: A Tree view widget is the interaction of the user to browse with the represented hierarchical representation.A Tree view, also known as an 'Outline view,' is the graphical visualization of a hierarchical representation of data with every item having more sub-items.Let us now break the words down we'll learn about each of them one after the other: This tutorial explains the following contents: Using Tkinter, we can display information in hierarchical representation using Treeview.
