Thx. In fact, it scrolls when I call SetScrollTop on the
nsIDOMNSHTMLElement interface of that DIV. But HOW FF finds the
"right" HTML element to set the scroll top to? I mean, when I move the
scrollbar, FF scrolls, right?
"The scrollbar" is just attached to the scrollable element in this case.
Here, try this testcase to see what's going on:
<!DOCTYPE html>
<body>
<div style="overflow:auto; height: 200px">
<div style="height: 1000px"></div>
</div>
<div style="overflow:auto; height: 200px">
<div style="height: 1000px"></div>
</div>
</body>
Note how each scrollbar just corresponds to the thing that scrolls.
Also note how there is more than one scrollbar.
