DBus Notification

This library provides a simple interface for creating and displaying desktop notifications with custom buttons using DBus.

Features:

• Send notifications with custom titles, messages, and images
• Interactive Buttons: Include clickable buttons that trigger callbacks
• Urgency & Sounds: Control urgency levels (0, 1, or 2) and trigger system sounds or file-based alerts
• Management: Replace, close, or clear all notifications sent by the application
• Unique Tracking: Use uniqueid to update specific notifications without managing raw notification IDs Note: Some features might have limited support depending on your desktop environment.

Requirements

DBus Notification has minimal system dependencies:

• Python 3.7 or later
• jeepney library

Installation

Install the library using pip:

pip install dbus-notification

Usage

Command-Line Interaction

You can send quick notifications directly from your terminal using the following flags:

Example:

dbus-notification -t "Hello" -m "This is a test" -u 1

Programmatic Control

The DBusNotification class allows for advanced interaction and button callbacks.

import time
from dbus_notification import DBusNotification

def callback(notification_type, notification):
    if notification_type == "closed":
        print(f"Notification {notification['id']} has closed.")
    elif notification_type == "button":
        print(f"Notification {notification['id']} has clicked on the button {notification['button']}.")

dbus_app = DBusNotification(appname="dbus_notification", callback=callback)

notification_id = dbus_app.send(
    title="Initial Message",
    message="This message will be replaced in 3 seconds.",
    logo="logo.png",
    image="myimage.png",
    sound="message-new-instant",
    actions=["Test Button"],
    urgency=1,
    timeout=5000, # 5 seconds
    uniqueid="test_notification",
)
time.sleep(3)

notification_id = dbus_app.send(
    title="Updated Message",
    message="This is the new message body.",
    uniqueid="test_notification",
)
time.sleep(3)
dbus_app.close(notification_id)

dbus_app.send(title="N2", message="A second notification.")
dbus_app.send(title="N3", message="A third notification.")
time.sleep(3)

dbus_app.close()
