How can I guarantee a specific label is shown on the screen?

Question

I am trying to write a mobile Air application and have a large number of labels, which scroll off the screen.

I would like to guarantee a specific label (I would know the label's ID) would be visible on the screen (ie scrolled to, say, the centre of the screen.

I have tried verticalScrollPosition but cannot seem to get the correct value for the position.

Any ideas on how to do this would be appreciated.

The solution I have used is as follows:

rhs.verticalScrollPosition = (currentLine*myCurrentSize*1.2); //1.2 is the leadingHeight = 1.2%

Where rhs = the contained id (in this case a VBOX)

currentLine = The line nmber I want to display on the screen (eg 55)

myCurrentSize = fontSize of the fonts on each line

1.2 (a constant = leadingHeight of the font, as this is 120% by default, you can change this is you set the leadingHeight of the fonts)

You can move the displayed line to the middle of the screen by subtracting half the container height.
