Why start from a template?

A blank window is the slowest part of building a GUI. Each template here is a complete, working design, with widgets already placed and named, and handler code that actually does something, so you can run it before you change a line. That makes them useful in two ways: as a starting point you edit into your own app, and as a worked example of how a particular tkinter pattern fits together.

They cover the patterns that come up most: reading text from an Entry, wiring a Button to a method, adding and removing rows in a Listbox, grouping Radiobuttons and reading the choice, and updating a Label to show a result. Between them, the five templates use most of the widgets you'd reach for in a first real project.

How to use one

  1. Open it. "Open in designer" drops the template straight onto the canvas. If you already have work in progress, you'll be asked before anything is replaced.
  2. Make it yours. Move and resize widgets, change their text and colours, add your own, and edit the handler code. The generated Python updates as you go.
  3. Download and run. Export main.py and run it with python main.py. Nothing to install, and no framework in the output.

Every template exports standard tkinter by default, so the code runs on any machine with Python and nothing else. Switch the toolkit and the same design exports CustomTkinter instead, with modern rounded widgets and a dark mode.

Building something else?

Start from an empty window in the online tkinter designer, or read the step-by-step guide to see how a build goes from first widget to python main.py. If you're weighing up tools first, see what matters when choosing a tkinter GUI builder.
