How do I tell if a text object is showing ALL its text?

I want to determine if a text object is large enough to show all the text it is supposed so if not, I can show an ellipses (...) if not.

Are there any conditions to test for this?

perhaps you can use the expression text.textheight and text.textwidth then resize the text object (works also with spritefont object)

Note: the Text object must be drawn before these have the correct values( C2 needs a delay between 0.1 and 0.2 sec)
