Hi Jim,
Several questions first :
- Are you using a vector layer with a strategy, a protocol and a KML format
?
- Are you extracting styles from the KML file (extractStyles property set
to true in the KML format) ?
- Did you attempt to replace the styles using a StyleMap at the layer level
?
- Did you refresh by calling redraw on the layer ?
One thing to know is that extracting styles from a KML file will set a
"style" property at the feature level. Applying a "stylemap" at the layer
level will no take precedence.
For example, if you try the following in the kml-layer.html example, only
one feature will change ; the one that has no predefined style :
------------------
var layer = map.layers[1];
layer.styleMap = new OpenLayers.StyleMap({'default': {fillColor: '#FF0000',
strokeColor: '#0000FF', strokeWidth: 4}});
layer.redraw();
------------------
So if you want to change the style of features in case you extracted styles
from the KML file, you will have to change the styles for each one :
------------------
layer.features[2].style.strokeColor = '#00ff00';
layer.redraw();
------------------
Regards,
Pierre
