Wails窗口透明的真正配置

package main

import (
	"embed"

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

//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:  "wails2-20250930",
		Width:  800,
		Height: 600,
		AssetServer: &assetserver.Options{
			Assets: assets,
		},
		BackgroundColour: nil,
		WindowStartState: options.Normal,
		Frameless:        true, // 无边框窗口
		Windows: &windows.Options{
			WebviewIsTransparent:              true, // WebView 透明
			WindowIsTranslucent:               true, // 窗口半透明
			DisableFramelessWindowDecorations: true, // 禁用窗口装饰
		},
		OnStartup: app.startup,
		Bind: []interface{}{
			app,
		},
	})

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