Building Cross Platform Desktop apps with Golang

Introduction:

Golang, known for its simplicity and efficiency, is an excellent choice for developing cross-platform desktop applications. In this article, we will explore Fyne, a modern and easy-to-use GUI toolkit for Golang, to create sleek and responsive desktop applications.

Setting Up Your Development Environment:

To get started, make sure you have Golang and GCC installed on your machine. Once installed, set up your development environment by creating a new directory for your project and initializing it with go mod :

$ mkdir my-fyne-app
$ cd my-fyne-app
$ go mod init my-fyne-app
$ go get fyne.io/fyne/v2@latest

To get more details about how to set up your environment you can refer to the Fyne official documentation => https://developer.fyne.io/started/

For Debian/ubuntu, you will need to install Go, gcc and the graphics library header files using your package manager :

$ sudo apt-get install golang gcc libgl1-mesa-dev xorg-dev

Creating Your First Desktop App:

Let’s create a simple “Hello Fyne” application. Create a file named main.go and add the following code:

package main

import (
    "fyne.io/fyne/v2/app"
    "fyne.io/fyne/v2/container"
    "fyne.io/fyne/v2/container/layout"
    "fyne.io/fyne/v2/container/widget"
)

func main() {…
