fyne static resources

static resources

The static resource of fyne is actually to compile the resource file into a binary file, and then directly pass it in as a variable in the code. The advantage of this is that there is no need for additional image resources when packaging fyne applications .
The following commands are required

//这个命令是把 image1.png 编译为名叫 bundled.go 的二进制文件
fyne bundle image1.png >> bundled.go
//这个命令是把 image1.png 添加到为名叫 bundled.go 的二进制文件
fyne bundle -append image2.png >> bundled.go

The second command specifies -appendthe option to add to the existing file, and the generated file is as follows:

// auto-generated  
// Code generated by '$ fyne bundle'. DO NOT EDIT.  
  
package main  
  
import "fyne.io/fyne/v2"  
// resourceIconIco 就是你要调用的资源变量名
var resourceIconIco = &fyne.StaticResource{  
   StaticName: "icon.ico",  
   //下面括号中内容过多，就不放源码了
   StaticContent: []byte(...),  
}

Then you can call this variable directly in the code. Here is an example of setting the application icon

package main  
  
import (  
   "fyne.io/fyne/v2/app")  
  
func main() {  
   a := app.New()  
   a.SetIcon(resourceIconIco)  
   a.Run()  
}
