Class 1: Fyne GoLang GUI Course – Introduction and First Program

 

Welcome to the first class of our Fyne and GoLang GUI course! ???? In this tutorial, we will dive into the basics of creating graphical user interfaces with Fyne using GoLang. We’ll start with a simple program that is only 5 lines of code, covering the following steps:

STEP:1 Define the main package

package main

STEP:2 Import the Fyne library

import "fyne.io/fyne/v2/app"

STEP:3 Define the main function

func main() {}

STEP:4 Create a new app instance

a := app.New()

STEP:5 Create a new window with a title

w := a.NewWindow("I am New Win")

STEP:6 Show the window and run the app

w.ShowAndRun()
STEP:7 Run your project in the terminal
go run main.go

SOURCE CODE


package main // Define the main package

import "fyne.io/fyne/v2/app" // Import the Fyne library

func main() { // Define the main function
a := app.New() // Create a new app instance
w := a.NewWindow("I am New Win") // Create a new window with a title
w.ShowAndRun() // Show the window and run the app
}
