Python GUI Programming Cookbook

Combo box widgets

In this recipe, we will improve our GUI by adding drop-down combo boxes that can have initial default values. While we can restrict the user to only certain choices, at the same time, we can allow the user to type in whatever they wish.

Getting ready

This recipe extends the previous recipes.

How to do it...

We are inserting another column between the Entry widget and the Button using the grid layout manager. Here is the Python code.

ttk.Label(win, text="Choose a number:").grid(column=1, row=0)  # 1
number = tk.StringVar()                         # 2
numberChosen = ttk.Combobox(win, width=12, textvariable=number) #3
numberChosen['values'] = (1, 2, 4, 42, 100)     # 4
numberChosen.grid(column=1, row=1)              # 5
numberChosen.current(0)                         # 6
