Thanks very much for your replies, everybody. This has all been very useful information. :)
Ali, you were correct that the issue I was having with evas_object_textblock_size_native_get() was due to the object not being visible when I ran the function. I've gotten used to other functions applying when a textblock was still hidden (modifiers for geometry, content etc) that it didn't occur to me that visibility could have had an impact. I'll keep that in mind in future. Cheers, Dave.
