It has gained significant attention in the Linux community for its robust features and user-friendly interface.

Step-by-Step Installation & Setup Guide

Prerequisites

Before you begin, ensure you have Python 3.9 or higher installed on your system. Some Python dependencies, such as dbus-python, require system libraries to be present at build time.

Installation

1. Clone the repository

   git clone https://github.com/rafatosta/zapzap.git
   cd zapzap
   

2. Install dependencies

   pip install -r requirements.txt
   

3. Build & Run Locally

   python run.py [dev|preview|build] [--build-translations | --appimage | --flatpak-onefile]
   

   The executable will be generated in the dist/ folder as zapzap.flatpak.

Install as Python module

pip install .

Uninstall

pip uninstall zapzap

Using uv tool

Provides a global zapzap command in an isolated environment.

uv tool install . --with-requirements requirements.txt

Packaging

• Fedora Copr: Fedora Copr
• Flatpak: Flathub

System Dependencies for Fedora 43+

On Fedora 43 and newer, you may encounter issues with dbus-python due to missing development files. Install the required system dependencies first:

sudo dnf install -y dbus-devel pkg-config gcc python3-devel

After that, install the Python dependencies normally:

pip install -r requirements.txt

REAL Code Examples from the Repository

Example 1: Main Application Entry Point

The main entry point of the ZapZap application is defined in run.py. This file initializes the application and handles the main loop.

# run.py
import sys
from PyQt6.QtWidgets import QApplication
from zapzap.controllers.main_window import MainWindow

if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec())

In this code snippet, we import the necessary modules and create an instance of QApplication. The MainWindow class is instantiated and displayed, and the application loop is started.

Example 2: Custom Window Decorations

ZapZap allows for custom window decorations, enhancing the user experience.

# controllers/main_window.py
from PyQt6.QtWidgets import QMainWindow
from PyQt6.QtCore import Qt

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle('ZapZap')
        self.setWindowFlags(Qt.Window | Qt.CustomizeWindowHint)
        self.setWindowDecorations()

    def setWindowDecorations(self):
        # Custom window decorations code here
        pass

This code sets up the main window and customizes its decorations. The setWindowDecorations method can be expanded to include custom styles and behaviors.

Example 3: System Tray Integration

ZapZap integrates with the system tray to provide notifications and quick access.

# controllers/main_window.py
from PyQt6.QtWidgets import QSystemTrayIcon, QMenu
from PyQt6.QtGui import QIcon

self.tray_icon = QSystemTrayIcon(QIcon('icon.png'), self)
self.tray_icon.setContextMenu(self.createSystemTrayMenu())
self.tray_icon.show()

def createSystemTrayMenu(self):
    menu = QMenu(self)
    menu.addAction('Exit', self.quit)
    return menu

Here, we create a system tray icon and a context menu with an 'Exit' option. The QSystemTrayIcon is displayed, and the context menu is set to provide quick actions.

Example 4: Keyboard Shortcuts

Keyboard shortcuts are implemented to enhance usability.

# controllers/main_window.py
from PyQt6.QtWidgets import QShortcut
from PyQt6.QtGui import QKeySequence

self.shortcut_exit = QShortcut(QKeySequence('Ctrl+Q'), self)
self.shortcut_exit.activated.connect(self.quit)

This code sets up a keyboard shortcut for exiting the application. The QShortcut class is used to bind the Ctrl+Q key combination to the quit method.
