RE: [Flashcoders] Prevent Multiline Selectable TextFieldfromscrolling?
Tried that... creates this nasty jumping effect as it snaps back into
place.

onScroll event method, and revert the scroll value back to some saved
value...

Oddly enough, I am - but it still scrolls. It's almost as though there's
an
extra newline or something in there.

Only thing I can think of right now is always showing all of the
text, and masking the portion you want to hide...

be a TextField.scrollable:Boolean.
Ideas?

Re: [Flashcoders] Prevent Multiline Selectable TextFieldfromscrolling?
There's no simple property for this but I was able to put together an
example that works (check below for the caveats):
var o;
var i:Number;
var tf = t.getTextFormat();
var linesOfText:Number = 2;
var originalText:String = t.text;
for (i=0; ioriginalText.length; i++)
{
o = tf.getTextExtent(originalText.substr(0, i));
if (o.width 2 * t.textWidth o.width linesOfText * t.textWidth -
20)
{
t.text = originalText.substr(0, i);
break;
}
}
It's a little funky, but extending Flash textfield seems to always be like
that.
What it does is store the original text and populate the textfield with
text only up until it would scroll.
Here are the caveats:
1. The number in the if condition (20) is a guess. If I had the time to
spend on this I would calculate the size before the next word. As it is
now 20 seemed to work for the text that I had.
2. The text will be from the 0 character onwards. If you have a scrollbar,
or other means of scrolling, the scrollPosition will not be taken into
account.
Again, if I had the time this could probably be made to compensate for the
caveats.
Hope it helps.

RE: [Flashcoders] Prevent Multiline Selectable TextFieldfromscrolling?
Interesting approach, Derek. I've actually done something similar in the
past for paginating purposes, but it didn't occur to me to do it for this.
Of course, it gets really hairy if you're dealing with HTML, but still
doable.
Thanks!
