说明

窗口弹出事件

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
