Add option to disable window re-focus when go app reloads

[birdmanmandbir]

This PR adds option to disable window re-focus when go app reloads. #1495

Application options

I created a new property in the App options, It defaults to false

How to test

• with NoDesktopOnDev: true, run wails dev not open the desktop app and http://localhost:34115 have normal behavior
• with NoDesktopOnDev: true, run wails build, the executable have normal behavior
• with NoDesktopOnDev: false, run wails dev open the desktop app

Current functionality is working. I also wrote the documentation for En and Zh-Hans.

Below is an example main.go file that can be used as a test in a clean wails project

package main

import (
	"embed"

	"github.com/wailsapp/wails/v2"
	"github.com/wailsapp/wails/v2/pkg/options"
	"github.com/wailsapp/wails/v2/pkg/options/assetserver"
)

//go:embed all:frontend/dist
var assets embed.FS

func main() {
	// Create an instance of the app structure
	app := NewApp()

	// Create application with options
	err := wails.Run(&options.App{
		Title:  "wails-vue",
		Width:  1024,
		Height: 768,
		AssetServer: &assetserver.Options{
			Assets: assets,
		},
		BackgroundColour: &options.RGBA{R: 27, G: 38, B: 54, A: 1},
		OnStartup:        app.startup,
		Bind: []interface{}{
			app,
		},
		Debug: options.Debug{
			StartHiddenOnDev: true,
		},
	})

	if err != nil {
		println("Error1:", err.Error())
	}
}

You may be able to get the same functionality if you set StartHidden: true in your application options?

I have try it, but with StartHidden: true, The window will also hidden in production mode after wails build, but I only want to hidden in dev mode, and It's easy to forget to remove the option when wails build

Maybe you could add a flag that overrides the 'StartHidden' to the debug options in the appoptions?

You are right, I have moved it to Debug.StartHiddenOnDev

I see this as more a cli flag because as you said, it's easy to forget it when you build. I'm going to add this to v3. Feel free to use a fork of v2 with this patch until it's released.
