How to Create a Python IMGUI Application?

Estimated read time 2 min read

In Python, you can create an Immediate Mode Graphical User Interface (IMGUI) application using the PyImGui library, which is a Python wrapper for the popular Dear ImGui library.

Here’s an example of how to create a basic PyImGui application that displays a window with a text input field and a button:

import imgui
from imgui.integrations.pygame import PygameRenderer
import pygame

# Initialize Pygame
pygame.display.set_caption("My IMGUI Application")

# Create a Pygame window
window_size = (800, 600)
screen = pygame.display.set_mode(window_size)

# Create a Pygame renderer for PyImGui
renderer = PygameRenderer()

# Main application loop
while True:
    # Handle Pygame events
    for event in pygame.event.get():
        if event.type == pygame.QUIT:

    # Start a new PyImGui frame

    # Create a text input field
    text_input_buffer = imgui.input_text("Enter some text", max_length=50)

    # Create a button that prints the text input value
    if imgui.button("Submit"):
        print(f"You entered: {text_input_buffer}")

    # End the PyImGui frame and render it to the Pygame window

This code uses Pygame to create a window and handle events. It then initializes PyImGui and creates a Pygame renderer for PyImGui.

In the main application loop, it starts a new PyImGui frame and creates a text input field using the imgui.input_text() function. It also creates a button using the imgui.button() function that prints the text input value when clicked.

Finally, it ends the PyImGui frame and renders it to the Pygame window using the renderer. It then updates the Pygame window using pygame.display.flip().

You can customize this code to create more complex IMGUI applications with additional widgets and functionality, such as sliders, menus, and graphs.
