详细说明
TouchSelectionMenuRequest 作为 WebEngineView::touchSelectionMenuRequest 信号的参数传递。它提供了有关请求上下文的更多信息。selectionBounds 属性提供了请求的来源。
请求的accepted 属性表示该请求是由用户代码处理还是显示默认的触摸选择菜单。
以下代码使用自定义菜单来处理请求：
WebEngineView { id: view // ... onTouchSelectionMenuRequested: function(request) { request.accepted = true; myMenu.x = request.selectionBounds.x; myMenu.y = request.selectionBounds.y; myMenu.trigger.connect(view.triggerWebAction); myMenu.popup(); } // ... }

表示触摸选择菜单请求是否已由信号处理程序处理。
如果在执行WebEngineView::touchSelectionMenuRequested 的任何信号处理程序后，属性为false ，则将显示默认触摸选择菜单。为防止出现这种情况，请将request.accepted 设置为true 。
默认值为false 。
注： 触摸选择菜单的默认内容取决于实际生成请求的网络元素。
