Create Roll Over + XML

Dear Reader,

My subject may sound it littile odd …sorry for it

I have a say 10 textfields on the stage. They are getting created dynamically using createTextField. Now these textfiedl has got a fixed width and height which I can not change or can not make autoSize/wordWrap/multiline.

What I want to do is when the text length is greater than the textfield I want to create RollOver. When the user couldnt read complete text he can have a roll over which displays the complete text. Can some one help me out or give me a hint.

We can assume text length is always going to be greater than the textfield if creating rollovers for the specific textfield would be a problem means rollover for all textfields.
