如何以编程方式导航 WPF UI 元素制表位?

问题描述

谁能告诉我如何以编程方式浏览 WPF 应用程序中的所有 UI 元素制表位?我想从第一个制表位开始嗅探对应的元素，访问下一个制表位，嗅探对应的元素，依此类推，直到到达最后一个制表位.

Can anyone tell me how to programmatically navigate through all UI element tab stops in a WPF application? I want to start with the first tab stop sniff the corresponding element, visit the next tab stop, sniff the corresponding element, and so on until I reach the last tab stop.

谢谢，- 迈克

推荐答案

您可以使用 MoveFocus 执行此操作，如此 MSDN 文章中所示，该文章解释了有关焦点的所有内容:焦点概览.

You do that using MoveFocus as shown in this MSDN article which explains everything about focus: Focus Overview.

这里是一些示例代码，用于获取下一个焦点元素(从那篇文章中获得，稍作修改).

Here is some sample code to get to the next focused element (got it from that article, slightly modified).

// MoveFocus takes a TraversalRequest as its argument.
TraversalRequest request = new TraversalRequest(FocusNavigationDirection.Next);

// Gets the element with keyboard focus.
UIElement elementWithFocus = Keyboard.FocusedElement as UIElement;

// Change keyboard focus.
if (elementWithFocus != null)
{
    elementWithFocus.MoveFocus(request);
}
