<div class=Section1>
<p class=MsoNormal>When you put a control on a map, OpenLayers builds a rather
cryptic classid for it based on the class name. You can supply your own replacement
for part of it, but OpenLayers appends ItemActive or ItemInactive to the class,
depending upon the state of the control.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This class is used to select a css rule that defines the
image to be displayed on the control.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>If the image doesn't exist, or the rule isn't specified, or
the css file wasn't included, or the constructed class name doesn't match
exactly, the control is invisible.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This just isn't right. I just helped another programmer
in our shop fix this, after he'd spent quite a few hours tracking down what
turned out to be a css file inclusion problem. He'd assumed that since he
couldn't see his controls, he had a problem in his OpenLayers configuration
objects.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>How hard would it be to set some defaults for the control
appearance that will work, even if the image file or the css file isn't
present? I'm not thinking something fancy, just a solid color would
do. Just something to indicate that the control actually has been loaded,
when the control has been loaded.<o:p></o:p></p>
