creating a global hotkey for a python application in the gnome desktop environment can be a powerful way to trigger actions within your application from anywhere in your linux system. in this tutorial, we'll walk you through the steps to create a global hotkey for a python application using the python-xlib library. we'll also provide you with a code example to demonstrate the process.
before we get started, make sure you have the following prerequisites:
python: ensure that python is installed on your system. you can check the installed version using python --version.
python-xlib: this library allows you to work with the x window system, which is used in the gnome desktop environment. you can install it using pip:
gnome shell: this tutorial is specifically for the gnome desktop environment. make sure you are using gnome shell as your desktop environment.
a global hotkey is a keyboard shortcut that can be triggered from anywhere in the system, even if your python application is not in focus. to achieve this, we'll be using the python-xlib library to listen for specific key combinations.
let's create a python script for our application with the global hotkey functionality. in this example, we'll create a script that opens a message box when the hotkey (ctrl+alt+h) is pressed.
create a new python file, e.g., global_hotkey_example.py, and add the following code:
in this code, we define the hotkey as ctrl+alt+h ([x.controlmask, x.mod1mask, x.h]) and specify a callback function (handle_event) that will be executed when the hotkey is pressed.
save the script and open a terminal. navigate to the directory where the script is located and run it:
the script will start listening for the ctrl+alt+h hotkey. when you press this hotkey combination, it will print a message. you can replace the print statement with your desired action, such as opening a window or performing any other task.
now, test the global hotkey. press ctrl+alt+h from anywhere in your gnome desktop environment, ...
