ezqt-app 5.5.2

Lightweight framework based on PySide6 to quickly build modern desktop applications, with integrated resource, theme, and reusable component management.

EzQt-App

EzQt-App is a lightweight Python framework based on PySide6 to quickly build modern desktop applications, with integrated resource, theme, translation, and reusable component management. Built on a hexagonal architecture for clean separation of concerns.

📦 Installation

pip install ezqt-app

Or from source:

git clone https://github.com/neuraaak/ezqt-app.git
cd ezqt-app && pip install .

🚀 Quick Start

import sys
from ezqt_app.app import EzQt_App
from ezqt_app.services.application.app_service import AppService

# Initialize and run the framework
app_service = AppService()
app_service.initialize()

# Create main window
window = EzQt_App(themeFileName="main_theme.qss")

# Add navigation menus
home_page = window.addMenu("Home", "🏠")
settings_page = window.addMenu("Settings", "⚙️")

# Show application
window.show()
app_service.exec()

🏗️ Architecture

EzQt-App follows a hexagonal architecture with three main layers:

src/ezqt_app/
├── domain/          # Contracts, ports, models, errors (no dependencies)
│   ├── ports/       # Abstract interfaces (AppPort, ConfigPort, etc.)
│   ├── models/      # Domain models
│   └── errors/      # Domain exceptions
├── services/        # Adapters implementing domain ports
│   ├── application/ # App lifecycle (AppService, InitService)
│   ├── config/      # Configuration (ConfigService, SettingsService)
│   ├── translation/ # i18n (TranslationService, AutoTranslator)
│   └── ui/          # UI coordination (ThemeService, MenuService)
├── widgets/         # PySide6 presentation layer
│   ├── core/        # Header, Menu, PageContainer
│   └── extended/    # SettingWidgets and advanced components
├── shared/          # Cross-cutting utilities
├── cli/             # Command-line interface
└── app.py           # Main EzQt_App entry point

🧪 Testing

Comprehensive test suite with 426+ test cases covering services, widgets, and integration scenarios.

# Install dev dependencies
pip install -e ".[dev]"

# Run all tests
pytest tests/

# Run by marker
pytest tests/ -m unit
pytest tests/ -m integration

# With coverage
pytest tests/ --cov=src/ezqt_app --cov-report=html

# Using CLI
ezqt test --unit
ezqt test --coverage

See the Testing Guide for complete details.

🖥️ CLI Commands

Project Management

# Initialize new project (assets, QRC, resources)
ezqt init [--force] [--verbose] [--no-main]

# Create project from template
ezqt create --template basic --name my_app
ezqt create --template advanced --name my_app

# Show project information
ezqt info

Development Tools

# Convert .ts translation files to .qm
ezqt convert [--verbose]
ezqt mkqm [--verbose]

# Run tests
ezqt test [--unit] [--integration] [--coverage]

# Serve documentation
ezqt docs [--serve] [--port <port>]

🌍 Translation System

# Use Qt's standard translation call — EzTranslator intercepts automatically
from PySide6.QtCore import QCoreApplication
text = QCoreApplication.translate("EzQt_App", "Hello World")

# Change active language (triggers LanguageChange on all widgets)
from ezqt_app.services.translation import get_translation_manager
get_translation_manager().load_language("Français")

# Enable auto-translation: unknown strings are translated via external providers
# and progressively saved to .ts files, then compiled to .qm
window.enable_auto_translation(True)

Supported languages: English, Français, Español, Deutsch Translation providers: Google Translate, MyMemory, LibreTranslate (tried in order, daemon threads — UI never blocked) Auto-populate: .ts files are updated at runtime; .qm files are recompiled via pyside6-lrelease on each language load. Identity entries are written for the source language so en.ts is always populated.
