... we create them using the xpcom interface nsiatomservice and add them to the array using the appendelement() function.
... getservice(components.interfaces.nsiatomservice); props.appendelement(aserv.getatom("makeitblue")); } else { return "makeitblue"; } } } this function would be defined as part of a view object.

to add properties for a particular row, you must use the nsiatomservice to create an nsiatom string, which can then be appended to the array to alter the style (see also styling a tree) getrowproperties: function(index, properties) { var atomservice = components.classes["@mozilla.org/atom-service;1"].getservice(components.interfaces.nsiatomservice); var atom = atomservice.getatom("dummy"); properties.appendelement(atom); } hasnextsibling() used to determine...
