Thanks the article.
Btw, I am working with List on Flex Mobile. You can set clipAndEnableScrolling in HorizontalLayout of List and work with this instead of List

@Steve
Yes, I just preformed a similar task to a list, for a list you must use list.layout to use the “getHorizontalScrollPosition” function and animation to work… This means the layout must be bindable.. which was a bit tricky to do… I just made the layout itself a bindable veriable, and made the lists layout = the bindable layout at creationcomplete.

hope this helps

Hi,
how to use a scrollbar to change the index?
Lets say you have 99 pages and want to quickly jump to page 88.. :)
With this above you have to press 88 Times the Arrow.

How would I directly jump to a specific index ? How do I get the delta ?

Can you do something similar with an entity that can have data bound to it, like a List?

I did this, and it works:

protected function scrollToThere(dir:uint):void {
var value:Number = hGr.getHorizontalScrollPositionDelta(dir);
if (value != 0) {
pth.valueBy = value;
anim.play();
}
else
{
if(dir == NavigationUnit.PAGE_RIGHT)
{
value = hGr.getHorizontalScrollPositionDelta(NavigationUnit.HOME);
pth.valueBy = value;
anim.play();
}
if(dir == NavigationUnit.PAGE_LEFT)
{
value = hGr.getHorizontalScrollPositionDelta(NavigationUnit.END);
pth.valueBy = value;
anim.play();
}
}
}

but I was looking for a more continuous effect where it keeps going in the same direction.

Very nice, this is something I was looking for. Is there a way to loop to the beginning once you reach the end?
