Autocomplete Python Tkinter

Python Tkinter provides a module ttkwidgets using which we can add autocomplete feature in our application in Python Tkinter.

  • ttkwidgets have method autocomplete which allows the developer to easily implement autocomplete feature in their respective application.
  • The first step in the process is to install Autocomplete on the system. Windows and Mac users can simply use pip to install autocomplete whereas Linux users have to install the complete package to use it.
  • ttkwidgets is dependent on the pillow, so we need to install that as well on the system to make this ttkwidgets library work.

Windows and Mac users:

pip install ttkwidgets
pip install pillow

or

pip3 install ttkwidgets
pip3 install pillow

For Linux, we will be using Ubuntu which has an apt as package manager. You can change apt to your respective package manager. Arch Linux users click here.

sudo add-apt-repository ppa:j-4321-i/ttkwidgets

sudo apt-get update

sudo apt-get install python3-ttkwidgets

sudo apt-get install python-imaging-tk

Once you have executed all these commands successfully you can follow the steps in the below sections to implement the autocomplete feature in Python Tkinter.

Autocomplete Entry Tkinter Python

In this section, we will learn how to autocomplete the Entry widget in Python Tkinter. Also, we will see an example of it.

  • the first step in the process is to import the AutocompleteEntry method from ttkwidgets.autocomplete
  • Now instead of creating an Entry widget directly from Tkinter, we will create using AutocompleteEntry, and inside it, we will pass a parameter for completevalues.
  • The values passed in completevalues parameter will become options that will be completed when the user will pass similar keywords.
  • for example, completevalues=['hello', 'PythonGuides'], now every time user will type ‘h; he/she will see autocomplete suggestion as ‘hello’, similarly in the case of ‘p’ he/she will see ‘pythonguides’ as an option.

        ]

ws = Tk()
ws.title('PythonGuides')
ws.geometry('400x300')
ws.config(bg='#f25252')

frame = Frame(ws, bg='#f25252')
frame.pack(expand=True)

Label(
    frame, 
    bg='#f25252',
    font = ('Times',21),
    text='Countries in North America '
    ).pack()

entry = AutocompleteEntry(
    frame, 
    width=30, 
    font=('Times', 18),
    completevalues=countries
    )
entry.pack()

ws.mainloop()
