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
