[OpenLayers-Users] overviewmap style properties

[Alessio Di Lorenzo]

Hi list,

I'm working on the overview map outside the map viewport and everything 
is going fine but I don't uderstand if it is possible to restyle the 
overview map (by deleting, for example, the blue border) without working 
directly on the style.css file.

I read the online docs concerning the minRectDisplayClass
http://dev.openlayers.org/releases/OpenLayers-2.6/doc/apidocs/files/OpenLayers/Control/OverviewMap-js.html#OpenLayers.Control.OverviewMap.OpenLayers.Control.OverviewMap

but I don't understand exactly how to use it and if this class is 
suitable to reach my purpouse... that is to manage the overview map style.

Could you give me some hints?

thx in advance, alessio
