[OpenLayers-Users] Right-click menu

[Graham Davis]

Well, I seem to have found the answer to my own question, so I thought 
I'd email it to the list just in case anyone else needs to know how.

Basically there is an oncontextmenu event for DOM objects.  You can 
assign this to a function and put any code you like in there, and then 
return false at the end to ensure the event stops and doesn't display 
the browser's context menu.  So I added this to my map object to disable 
all browser context menus from appearing on the map like so:

map.div.oncontextmenu = function noContextMenu(e) {return false;};

Seems to work well in both IE and FF (haven't test Opera or on a Mac).
