Creating tabbed widgets

In this recipe, we will create tabbed widgets to further organize our expanding GUI written in tkinter.

Getting ready

In order to improve our Python GUI using tabs, we will start at the beginning, using the minimum amount of code necessary. In this recipe, we will create a simple GUI and then add widgets from the previous recipes and place them into this new tabbed layout.

How to do it…

Create a new Python module and place the following code into this module:

GUI_tabbed.py

This creates the following GUI:

While not amazingly impressive as of yet, this widget adds another very powerful tool to our GUI design toolkit. It comes with its own limitations in the minimalist example above (for example, we can neither reposition the GUI nor does it show the entire GUI title).

While we used the grid layout manager for simpler GUIs in the previous recipes, we can use a simpler layout manager, and pack is one of them.

In the preceding code, we pack the tabControl and ttk.Notebook widgets...
