InvalidateSize without screen flash?

Question

Here's the scenario: I wait for a creationComplete event to occur for an mx:Text object at which point I can access the setTextFormat method of its protected member textField. (textField is not valid until creationComplete.) At that point the text formatting done through textField.setTextFormat increases the height of the text. But the mx:Text itself does not pick up this height change until I call invalidateSize. However, in my case invalidateSize causes the entire text to be redrawn, causing it to flash on the screen. However, if I just manually change the browser window size, the Text height change is made without the text flashing like that. So how could I through a function call accomplish what is taking place when I manually change the browser window size. (I just want mx:Text to pick up the height change accomplished through textfield.setTextFormat.)

Answer 1

did you tried to put your textfield inside a sprite or movieclip and scale it with your callback?

Answer 2

I was in fact able to avoid the screen flash by calling

  txt1.invalidateSize();    
  txt1.validateNow();

immediately after the calls to txt1.ui_txtfld().setTextFormat(....)

(ui_txtfld() is how I'm making the protected property textField visible.)

However, elsewhere in my code, it was also necessary to not reference txt1.height directly, but instead,

(txt1.ui_txtfld().textHeight+4)*txt1.scaleY,

as the txt1.textField.textHeight property is valid immediately after changing the height of a textField, whereas txt1.height is not.
