flash - Actionscript 3: How do I have a button that allows a group of buttons to rotate 90 degrees at a time? -

-

i'm new actionscript in adobe flash. have cluster of buttons navibar , want rotate 90 degrees @ time after each press of button. i've done research , i've found out rotating button impossible. of course, can try using movie clip instead of button, keep if possible.

you buttonname.rotation = 90 what's impossible that?

or if want rotate cluster (as in "...rotate it..." in question?), instead of individual buttons, put buttons inside of movieclip , rotate movieclip.
