[OpenLayers-Users] overview control

[Tim Schaub]

In hopes that these links show up at the top of the google search 
results for OverviewMap, I'll gather doc links here:

If you have trouble with the overview map control, please read:
http://trac.openlayers.org/wiki/Control/OverviewMap

If you want to set custom map options on the overview map control, find 
the bit on "Custom map options" on that page.
http://trac.openlayers.org/wiki/Control/OverviewMap#Custommapoptions-projectionsextentsetc.

If you like reading class documentation, please read:
http://dev.openlayers.org/apidocs/files/OpenLayers/Control/OverviewMap-js.html

If you want to see the bit where it describes the mapOptions property, 
click on the mapOptions property.
http://dev.openlayers.org/apidocs/files/OpenLayers/Control/OverviewMap-js.html#OpenLayers.Control.OverviewMap.mapOptions

If you want to learn by reading code and don't own a text editor, see
http://trac.openlayers.org/browser/trunk/openlayers/lib/OpenLayers/Control/OverviewMap.js

Specifically, you can read about the mapOptions property:
http://trac.openlayers.org/browser/trunk/openlayers/lib/OpenLayers/Control/OverviewMap.js#L68

Or, if you look a few lines farther down, you can read about the 
constructor, which mentions the mapOptions property:
http://trac.openlayers.org/browser/trunk/openlayers/lib/OpenLayers/Control/OverviewMap.js#L76

There, documented :)
