It looks like I have the right code. I think the problem is with the
styleValue routine. I have had to modify the following code in the draw
function:<br>
<br>
<tt> var vertDisp = 0;<br>
for(var classIndex = 0; classIndex < classNames.length;
++classIndex) {<br>
var cls = classNames[classIndex];<br>
vertDisp = Math.max(<br>
vertDisp,<br>
this.styleValue(cls, 'top') + this.styleValue(cls,
'height')<br>
);<br>
}<br>
if (vertDisp == 0) vertDisp = 30;<br>
</tt><br>
The vertDisp value was coming out to be zero. By adding the last line
and setting it to 30 it helped, but the bar still looks a bit off. I
load a number of style sheets and I think that there is an issue with
one that is causing the problem. I suspect the following code in
styleValue:<br>
<br>
<tt> if(typeof(sheet.cssRules) == 'undefined') {<br>
if(typeof(sheet.rules) == 'undefined') {<br>
// can't get rules, assume zero<br>
break;<br>
} else {<br>
allRules = sheet.rules;<br>
}<br>
} else {<br>
allRules = sheet.cssRules;<br>
}<br>
</tt><br>
I am wondering if the "break;" should be a "continue;"? Any thoughts?

If you take a look at the patch for the scale bar, you'll see there are
some changes required to the default stylesheet.
<a class="moz-txt-link-freetext" href="http://trac.openlayers.org/attachment/ticket/24/scalebar.patch">http://trac.openlayers.org/attachment/ticket/24/scalebar.patch</a>
In addition, you'll want to add your stylesheet with a link tag instead
of relying on the default dynamically added stylesheet.
<link rel="stylesheet" href="../theme/default/style.css" type="text/css" />
Thanks for trying it out. Write back if you still have any trouble with it.

<pre wrap="">Are you adding ScaleBar (which isn't in trunk) or Scale()? OpenLayers
does not currently have a ScaleBar control.
