Go language GUI framework encyclopedia: choose the tool that suits you best

With the rapid development of computer technology, Graphical User Interface (GUI) has become an indispensable part of human-computer interaction. As a powerful tool for developers to develop graphical interface programs, the GUI framework plays a vital role in improving the ease of use and aesthetics of the program. Among them, Go language is an efficient, concise, easy to learn and use programming language, and it also has many excellent GUI frameworks to choose from.

This article will introduce some commonly used Go language GUI frameworks, combined with specific code examples, to help developers choose the tools that best suit their project needs.

1. GoWalk

GoWalk is a cross-platform GUI library based on the Go language. It provides a wealth of controls and functions, making it extremely easy to develop beautiful GUI interfaces. The following is a sample code for creating a simple window using GoWalk:

package main

import (
    "github.com/lxn/walk"
)

func main() {
    walk.MainWindow{
        Title: "Hello, GoWalk",
        MinSize: walk.Size{Width: 300, Height: 200},
    }.Run()
}

2. Golang-UI

Golang-UI is a lightweight cross-platform GUI library written in Go language. Has a simple and easy-to-use API and fast layout functions. The following is a sample code for creating a button using Golang-UI:

package main

import (
    "github.com/andlabs/ui"
)

func main() {
    err := ui.Main(func() {
        button := ui.NewButton("Click Me")
        window := ui.NewWindow("Hello", 200, 100, false)
        window.SetChild(button)
        window.OnClosing(func(*ui.Window) bool {
            ui.Quit()
            return true
        })
        window.Show()
    })
    if err != nil {
        panic(err)
    }
}

3. Fyne

Fyne is a modern GUI library designed for the Go language, with an intuitive API and rich Control, supports cross-platform development. The following is a sample code to create a simple application using Fyne:

package main

import (
    "fyne.io/fyne/app"
    "fyne.io/fyne/widget"
)

func main() {
    myApp := app.New()
    myWindow := myApp.NewWindow("Hello")
    myWindow.SetContent(widget.NewLabel("Hello, Fyne!"))
    myWindow.ShowAndRun()
}

4. Gotk3

Gotk3 is a GTK 3 binding library in Go language, providing all the functions and features of GTK 3 , is a very powerful GUI development tool. The following is a sample code that uses Gotk3 to create a simple window:

package main

import (
    "github.com/gotk3/gotk3/gtk"
)

func main() {
    gtk.Init(nil)

    win, _ := gtk.WindowNew(gtk.WINDOW_TOPLEVEL)
    win.SetTitle("Hello")
    win.Connect("destroy", func() {
        gtk.MainQuit()
    })
    win.ShowAll()

    gtk.Main()
}

5. Lorca

Lorca is a GUI library based on the Chrome browser that allows developers to use the Go language to call front-end technology builds GUI application. The following is a sample code for using Lorca to create a simple window:

package main

import "github.com/zserge/lorca"

func main() {
    ui, _ := lorca.New("", "", 480, 320)
    defer ui.Close()

    ui.Load("data:text/html,<h1>Hello, Lorca!</h1>")
    <-ui.Done()
}

The above is a brief introduction and examples of several commonly used Go language GUI frameworks. Developers can choose the most suitable GUI tool based on their project needs and technical background, improve development efficiency and build beautiful and easy-to-use graphical interface applications. I hope this article can help the majority of Go language developers to better utilize the GUI framework for project development.
