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