弹出子窗口

go

)

//go:embed resources
var resources embed.FS

func main() {
	//全局初始化 每个应用都必须调用的
	cef.GlobalInit(nil, nil)
	//创建应用
	cefApp := cef.NewApplication()
	//指定一个URL地址,或本地html文件目录
	cef.BrowserWindow.Config.Url = "http://localhost:22022/index.html"
	cef.BrowserWindow.Config.IconFS = "resources/icon.ico"
	cef.BrowserWindow.SetBrowserInit(func(event *cef.BrowserEvent, window cef.IBrowserWindow) {

				popupWindow.HideTitle()
			} else if strings.Index(beforePopupInfo.TargetUrl, "popup_2") > 0 {
				popupWindow.SetSize(300, 300)
			}
			return false
		})
	})
	cef.SetBrowserProcessStartAfterCallback(func(b bool) {
		fmt.Println("主进程启动 创建一个内置http服务")
		//通过内置http服务加载资源
		server := assetserve.NewAssetsHttpServer()
		server.PORT = 22022
		server.AssetsFSName = "resources" //必须设置目录名
		server.Assets = &resources
		go server.StartHttpServer()
	})
	//运行应用
	cef.Run(cefApp)

说明

窗口弹出事件

go
cef.BrowserWindow.SetBrowserInit(func(event *cef.BrowserEvent, window cef.IBrowserWindow) {
    //chromium 弹出窗口事件
    event.SetOnBeforePopup(func(sender lcl.IObject, browser *cef.ICefBrowser, frame *cef.ICefFrame, beforePopupInfo *cef.BeforePopupInfo, popupWindow cef.IBrowserWindow, noJavascriptAccess *bool) bool {
        return false // 返回false执行框架默认逻辑
    })
})

在弱出窗口事件里,我们可以自定义弹出逻辑
