TKinter Form Tabs

Tabs are called Notebooks in the Tkinter ttk library. The idea is that you set up a parent Notebook and then add tabs to that Notebook.

In yiour code from the previous lesson, add the following line just after your geometry line and before mainloop:

tab_parent = ttk.Notebook(form)

In between the round brackets of Notebook, you need the name of a widget that the notebook is going on. For us, that's the main form. Our Notebook object is being held in a variable we've called tab_parent.

To set up a tab for your notebook, you create Form objects with the name of a Notebook between round brackets. Add these two lines:

tab1 = ttk.Frame(tab_parent)
tab2 = ttk.Frame(tab_parent)

This sets up two tab objects called tab1 and tab2. We now need to add them to the tab parent:

tab_parent.add(tab1, text="All Records")
tab_parent.add(tab2, text="Add New Record")

We're now using the add method of tab_parent. In between the round rackets of add, you need the name of the tab object you want to add. After a comma, we've added some text for the tab.

Finally, you need to pack the tab parent and its tabs:

tab_parent.pack(expand=1, fill='both')

The expand and fill option between pack ensure that the tabs fill the entire form. Your code should look like this:

Run your program again. You should now find that your form looks like this:

You can click your Add New Record tab to activate it. You won't see much difference as we haven't added any widgets to them. Let's do that now.
