是否有任何事件要处理，然后元素对用户是可见的? [英] Is there any event to handle then element is visual to user?

问题描述

Is there any event to handle then element is visual to user?

示例:列表框中有一些UI元素，但是所有项目都不可见，当用户滚动列表框时，元素是可见的.我想确定可处理读取操作的视觉对象.

Example: There are some UI elements in the listbox but all the items are not visual, when user scrolls the listbox then element is visual. I want to identify that visual to handle read operation.

推荐答案

以下线程可能有用:

不过，通常情况下，用户通常会滚动列表框，然后触摸需要编辑的元素，将焦点"移到该元素上，进而调用键盘.

Normally though, the user would typically scroll the listbox and then touch on the element that needs to be edited, shifting Focus to that element, which in turn invokes the keyboard.
