golang walk installation

Golang is a very popular programming language that has been widely used in many fields. Walk is a free Windows GUI library for writing Windows applications in Golang. This article will introduce how to install and use the walk library in Golang.

Step 1: Install Golang

First, you need to install Golang on your computer. You can download the installation package from the Golang official website https://golang.org/dl/. Select the version appropriate for your operating system, download and install. After the installation is complete, you can enter "go version" on the command line to verify whether Golang is installed correctly.

Step 2: Install GCC

GCC is an open source GNU compiler. The walk library requires CGO, so GCC needs to be installed. On Windows, you can download the MinGW-w64 installer, which contains GCC and the GNU toolset. It can be downloaded at http://mingw-w64.org/doku.php.

Step 3: Install DLL

walk library requires MSVCRT.DLL and USER32.DLL. These DLLs can be obtained from the Windows SDK or copied from the Windows system directory into Golang's bin directory.

Step 4: Install the walk library

You can use the "go get" command to install the walk library.

go get github.com/lxn/walk

Step 5: Test the walk library

After the installation is complete, you can try to write a simple Windows application to test whether the walk library is installed correctly. The following is a simple sample program:

package main

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

func main() {
    mw, _ := walk.NewMainWindow()
    mw.SetTitle("Hello World!")
    mw.SetSize(walk.Size{250, 150})
    mw.Show()
    walk.Run()
}

In the command line, enter the directory where the program is located, and use the "go run" command to run the program:

go run main.go

If everything goes well, you will see A window that displays the text "Hello World!"
