Python tkinter treeview4/30/2024 ![]() ![]() 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. Note: To generate the above picture, you should add/change the aforementioned lines of code in the example Treeview: Basic example.Python Tutorial Python Features Python History Python Applications Python Install Python Example Python Variables Python Data Types Python Keywords Python Literals Python Operators Python Comments Python If else Python Loops Python For Loop Python While Loop Python Break Python Continue Python Pass Python Strings Python Lists Python Tuples Python List Vs Tuple Python Sets Python Dictionary Python Functions Python Built-in Functions Python Lambda Functions Python Files I/O Python Modules Python Exceptions Python Date Python Regex Python Sending Email Read CSV File Write CSV File Read Excel File Write Excel File Python Assert Python List Comprehension Python Collection Module Python Math Module Python OS Module Python Random Module Python Statistics Module Python Sys Module Python IDEs Python Arrays Command Line Arguments Python Magic Method Python Stack & Queue PySpark MLlib Python Decorator Python Generators Web Scraping Using Python Python JSON Python Itertools Python Multiprocessing How to Calculate Distance between Two Points using GEOPY Gmail API in Python How to Plot the Google Map using folium package in Python Grid Search in Python Python High Order Function nsetools in Python Python program to find the nth Fibonacci Number Python OpenCV object detection Python SimpleImputer module Second Largest Number in Python The result is a treeview with modified fonts on both the body and headings, no border and different colors for the rows: Tree.tag_configure('even', background='#DFDFDF') Then, for instance, a background color can be associated to the tags: tree.tag_configure('odd', background='#E8E8E8') If you would like to have a different format depending on the rows, you can make use of tags: tree.insert(folder1, "end", "", text="photo1.png", values=("23-Jun-17 11:28","PNG file","2.6 KB"),tags = ('odd',)) Then, the widget is created giving the above style: tree=ttk.Treeview(master,style="mystyle.Treeview") Style.layout("mystyle.Treeview", ) # Remove the borders ![]() nfigure("", font=('Calibri', 13,'bold')) # Modify the font of the headings nfigure("mystyle.Treeview", highlightthickness=0, bd=0, font=('Calibri', 11)) # Modify the font of the body In this case, we create a style "mystyle.Treeview" with the following code (see the comments to understand what each line does): style = ttk.Style() By taking Treeview: Basic example, it can be shown how to customize a basic treeview. ![]()
