What Is GNOME

Create GNOME Applications in Python

"tkinter" - Python Interface for Tk GUI

Matplotlib - Plotting Library for Python

XQuartz - X11 Server for MacOS

Matplotlib Backends and Architecture

Matplotlib Backend TkAgg for X11 Servers

"ssh -AXY" to Avoid "Could not open X display" Error

Matplotlib Interactive vs. Non-Interactive Mode

Java GUI Applications on Linux

Takeaways:

GNOME (GNU Network Object Model Environment) is a free and open-source desktop environment for Unix/Linux operating systems.
You can use "gi.repository.Gtk" Python module to create GNOME applications.
You can install "tk" and "python3-tkinter" package to create "tkinter" applications in Python.
XQuartz is an X11 server for macOS computers.
You can run "tkinter" applications on both local GNOME desktop and remote X11 servers.
You can run "Matplotlib" Python scripts on local GNOME desktop with "GTK3Agg" backend.
You can run "Matplotlib" Python scripts on remote X11 server with "TkAgg" backend.
"ssh -AXY ..." command creates more stable display connections from remote X11 servers.
Call matplotlib.pyplot.draw() to force an update on the output in Matplotlib interactive mode.
Call matplotlib.pyplot.show() to sends the rendered image to the output device in Matplotlib non-interactive mode.
Java GUI apps can be displayed on both local GNOME desktop and remote X11 servers.
