Ara_imgui

Ara_imgui is a lightweight and easy-to-use wrapper around Dear ImGui using Python and GLFW. It simplifies GUI application development with ImGui by providing a convenient interface for managing windows, fonts, and application lifecycle.

Features

• Simple ImGui app launch with a single run function
• Support various themes
• System or custom font loading, including Cyrillic support
• Ready-to-run examples included in the examples folder

Installation

pip install ara_imgui

⚠️ Make sure you have Python 3.7+ and OpenGL support (e.g., via GPU drivers on Windows).

Usage

Basic example

from ara_imgui import App, imgui

app = App("Hello world example")

def gui():
    imgui.text("Hello, world!")
    if imgui.button("Click me"):
        print("Clicked!")

app.run(gui)

Custom fonts and themes

from ara_imgui import App, imgui

font_path = R"C:\Windows\Fonts\Arial.ttf"

app = App("Font Example")
app.apply_theme("cherry")
app.load_font(font_path, font_size=20)

def gui():
    imgui.text("Sample text with custom font")

app.run(gui)
