I use a TextArea dto display a large amount of text. On the iPhone I have the option for scrollable views to show an indicator when the user sees the respective view.
Is there a similar thing for Titanium?
After reading your question again, I think I understand what you mean, and your rationale behind it.
No, even though Ti.UI.ScrollView and Ti.UI.TextArea are both technically scroll views, and despite Ti.UI.ScrollView having the showHorizontalScrollIndicator and showVerticalScrollIndicator options, they unfortunately are not available in the Ti.UI.TextArea object. :(
