GTK+

Overview

GTK+ is a widely used, robust multi-platform toolkit for creating graphical user interfaces. It powers many Linux desktops and offers cross-platform support for Linux, Windows, and macOS. With PyGObject, Python developers can utilize GTK+ for building dynamic GUIs.

Key Features:

• Rich set of modern and traditional UI elements
• Cross-platform capabilities
• Accessible and internationalized development
• Native look and feel on all platforms
• Highly customizable and scalable

Common Use Cases:

• Desktop applications on Linux, Windows, and macOS
• Tools requiring rich graphic elements
• Enterprise software with GUI components
• Cross-platform development targeting different operating systems
• Embedded systems with GUI interfaces

Installation

# Install GTK+ development libraries and PyGObject bindings
# On Debian-based systems, you might use:
sudo apt-get install python3-gi python3-gi-cairo gir1.2-gtk-3.0

# Ensure that you have installed GTK+ dependencies for your platform

Example

import gi
gi.require_version("Gtk", "3.0")
from gi.repository import Gtk

class MyWindow(Gtk.Window):
    def __init__(self):
        super().__init__(title="Hello GTK+")
        self.set_default_size(200, 100)

        button = Gtk.Button(label="Click Me")
        button.connect("clicked", self.on_button_clicked)
        self.add(button)

    def on_button_clicked(self, widget):
        print("Hello World")

win = MyWindow()
win.connect("destroy", Gtk.main_quit)
win.show_all()
Gtk.main()
