Ara-imgui 1.1.0

A simplified wrapper for Dear ImGui and GLFW

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 for multiple ImGui windows via the Window class
• Built-in dark and light themes
• System or custom font loading, including Cyrillic support
• Ready-to-run examples included in the examples folder

Installation

pip install ara_imgui

Or install dependencies manually:

pip install glfw PyOpenGL imgui ara_core

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

Usage

Basic example

from ara_imgui import run, imgui

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

run(gui)

Multiple windows

from ara_imgui import App, Window, imgui

app = App("Multi-window App")

def win_ui():
    imgui.text("This is another window")

win = Window("Extra Window", frame_ui=win_ui)

def main_ui():
    imgui.text("Main Window")  
    if imgui.button("Open Extra Window"):
        app.add_window(win)

app.run(main_ui)

Custom fonts and themes

from ara_imgui import App, imgui

app = App("Font Example")
app.apply_theme("light")
app.load_font(font_size=18)

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

app.run(gui)

API

run(frame_ui, **kwargs)

Minimal interface to launch the application.

Parameters:

• hello_world.py — Basic "Hello, world!" with a button.
• basic_window.py — Simple window with input field.
• custom_font.py — Font and multilingual text rendering.
• multiple_window.py — GUI with multiple ImGui windows.
