Create an Import File Button with Tkinter

Graphical User Interfaces (GUIs) play a crucial role in enhancing the user experience of applications. Tkinter, a built-in Python library, provides a simple way to create GUI applications. In this article, we will focus on creating an “Import File” button using Tkinter.

Create An Import File Button With Tkinter

In this section, we will create an import file button with Tkinter in Python. Let’s create a basic Tkinter window with a button that allows users to import a file. Below is the step-by-step procedure by which we can create an import file button with Tkinter:

Step 1: Create a Virtual Environment

First, create the virtual environment using the below commands

python -m venv env
.\env\Scripts\activate.ps1

Step 1: Import Necessary Modules

In this step, we import the Tkinter library as `tk` and the `filedialog` module for file-related dialogs.

Python3

import tkinter as tk
from tkinter import filedialog

Step 2: Write Import File Logic

In this step, we define a function `import_file()` that uses `filedialog.askopenfilename` to prompt the user to select a file. If a file is selected, its path is printed to the console, providing a placeholder for custom file processing logic.

Python3

def import_file():
    file_path = filedialog.askopenfilename(title="Select a file", filetypes=[("Text files", "*.txt"), ("All files", "*.*")])
    if file_path:
        # Process the selected file (you can replace this with your own logic)
        print("Selected file:", file_path)

Step 3: Create Main Tkinter Window

In this step, we create the main Tkinter window using `tk.Tk()` and set its title to “Import File Example” with `root.title()`.

Python3

root = tk.Tk()
root.title("Import File Example")

Step 4: Create an “Import File” button

In this step, we create a Tkinter Button labeled “Import File” using `tk.Button()`. The button is associated with the `import_file` function using the `command` parameter. Finally, the `pack()` method is used to place the button in the window with vertical padding of 100 units.

Python3

# Create an "Import File" button
import_button = tk.Button(root, text="Import File", command=import_file)
import_button.pack(pady=100)

Step 5: Run the Code

In this final step, we start the Tkinter event loop with `root.mainloop()`, allowing the GUI to respond to user interactions and ensuring the window remains open until the user closes it.

Python3

# Run the Tkinter event loop
root.mainloop()

Complete Code

In this code, Tkinter is utilized to create a window with an “Import File” button that triggers a file selection dialog. The selected file path is printed to the console, offering a foundation for custom file processing logic.

Python3

import tkinter as tk
from tkinter import filedialog

def import_file():
    file_path = filedialog.askopenfilename(title="Select a file", filetypes=[("Text files", "*.txt"), ("All files", "*.*")])
    if file_path:
        # Process the selected file (you can replace this with your own logic)
        print("Selected file:", file_path)

# Create the main Tkinter window
root = tk.Tk()
root.title("Import File Example")

# Create an "Import File" button
import_button = tk.Button(root, text="Import File", command=import_file)
import_button.pack(pady=100)

# Run the Tkinter event loop
root.mainloop()

Output:

Output print the file path also in terminal
