TextFlow onChanged event?

is there sort of event track when text in textflow has changed?

you listen damageevent. gets sent whenever happens causes text require redraw:

 

textflow.addeventlistener(damageevent.damage, damagehandler);

 

if want find out after fact if text or formatting of textflow has changed, can check generation number. not quite same thing, changes controller, such resizing, not reflected in textflow's generation number.
