Scrollextent
 

Ok, another question. A lot of elements have the ScrollExtent tag, but they don't involve a scoll bar. So what does it do? The .doc file just says "amount you can scroll" But without a scrollbar, I don't see any scrolling getting done, so why is one being entered?

Thanks.

Scrollbars can be attached to most controlls, they are independent objects that you assign a target to.

For example, a page with size="100,100" might have a child object at location 200,200 (outside the visible region). If the scrollextent of the page is something like 300,300, you could attach a scrollbar to it that brings the child object into view while moving the other objects out of view.

Scrollocation can also be controlled via script without a scrollbar regardless of the scrollextent setting. Scrollextent is really only needed to help render an attached scrollbar properly. Technically I think the entire property can be omited if there's no scrollbar attached.

thank you.

Even without a scrollbar scrolling work with the mouse wheel.
