Hi,
I’m working on making an NSView accessible using the text area role. I’ve implemented accessibilityNumberOfCharacters, accessibilityValue, accessibilityStringForRange, accessibilitySelectedText, etc.. However, VoiceOver sometimes announces ‘end of text’ as I arrow down through text, despite the fact that the end of the content has not been reached. This can also happen sometimes at the end of lines. Additionally, logging the ranges being used when VO calls accessibilityStringForRange sometimes shows ranges that supposedly start after the last character of the content, or extend beyond the end of the content.
In order to help debug this, can I ask how VO determines what is the ‘end of text’. I assume that it relies solely on accessibilityNumberOfCharacters, but is this the whole story?
Best wishes.
Tim Burgess
