禁用表列的辅助功能 [英] Disabling accessibility for a table column

问题描述

我有一个正常的NSTableView显示轨道列表。我已经将一个表列专用于显示一个图标，指示当前正在播放哪个曲目。

I have a normal NSTableView that displays a list of tracks. I have dedicated a table column to displaying an icon that indicates which track is currently playing.

我正在添加更全面的VoiceOver支持，我不喜欢如何表中的每一行都被选中的第一个东西是image。我想禁用该特定表列的辅助功能。

I'm working on adding fuller VoiceOver support and I don't like how when each row in the table is selected the first thing said is "image". I would like to disable accessibility for that specific table column.

我知道我可以通过子类化NSTableView和/或NSTableColumn来返回YES从accessibilityIsIgnored。有没有办法做这个没有子类化？

I know I can do this by subclassing either NSTableView and/or NSTableColumn to return YES from accessibilityIsIgnored. Is there a way to do this without subclassing?

推荐答案

否。没有setAccessibilityIsIgnored这样的东西，所以你需要使用一个子类，当被询问-accessibilityIsIgnored时回答YES。

No. There is no such thing as "setAccessibilityIsIgnored" so you need to use a subclass that answers YES when asked -accessibilityIsIgnored.
