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:
var vertDisp = 0;
for(var classIndex = 0; classIndex < classNames.length;
++classIndex) {
var cls = classNames[classIndex];
vertDisp = Math.max(
vertDisp,
this.styleValue(cls, 'top') + this.styleValue(cls, 'height')
);
}
if (vertDisp == 0) vertDisp = 30;
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:
if(typeof(sheet.cssRules) == 'undefined') {
if(typeof(sheet.rules) == 'undefined') {
// can't get rules, assume zero
break;
} else {
allRules = sheet.rules;
}
} else {
allRules = sheet.cssRules;
}
I am wondering if the "break;" should be a "continue;"? Any thoughts? David

If you take a look at the patch for the scale bar, you'll see there are
some changes required to the default stylesheet.
http://trac.openlayers.org/attachment/ticket/24/scalebar.patch
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.

I am trying to get the OpenLayers.Control.ScaleBar working. I've added
it to my map according to the example html. However, when my map draws,
I get the units (in my case 'miles') but it displays at the bottom of

and hidden. Any thoughts on how to get this to work correctly? Thanks, David
Are you adding ScaleBar (which isn't in trunk) or Scale()? OpenLayers
does not currently have a ScaleBar control.
