41 * Propagate events involving PDB structures associated with sequences to a
42 * javascript function. Generally, the javascript handler is called with a
43 * series of arguments like (eventname, ... ). As of Jalview 2.7, the following
44 * different types of events are supported:
46 * <li>mouseover: javascript function called with arguments
49 * ['mouseover',String(pdb file URI), String(pdb file chain ID), String(residue
50 * number moused over), String(atom index corresponding to residue)]
54 * <li>colourstruct: javascript function called with arguments
57 * ['colourstruct',String(alignment view id),String(number of javascript message
58 * chunks to collect),String(length of first chunk in set of messages - or zero
63 * The message contains a series of Jmol script commands that will colour
64 * structures according to their associated sequences in the current view. Use
66 * .javascript.JalviewLiteJsApi.getJsMessage('colourstruct',String(alignment
67 * view id)) to retrieve successive chunks of the message.</li>
