GUI: Text justification?

I wasn't able to find anything in the docs, on Answers or the forum, but that doesn't necessarily mean that it doesn't exist, right? ;)

So: Is there a way - ANY way (BUT using a single pre-formatted texture for the whole text) - to justify a text within a TextArea?

Sure, I could use a single texture with all my text neatly aligned where I want it to be, but I need the text to be editable. But having the text aligned only to the left or right just looks not as good as a justified one.

(Just to be clear beyond any language barrier: With justify I mean to align the text on the left AND right side, making it essentially a block.)

No, Unity has no justification features like that. (Although justified text may look neater, it's actually harder to read, so there's that to keep in mind....)

A few asset extend Unity features, and do support text justification, as part of their text system.
Here is a video example of TextMesh Pro, thats actually made to integrate with all flavor of unity gui options and ngui (and possibly others).

edit: just noticed the 2010 dateā€¦ but might still be useful for other doing a search
