Hi, I am using Oxygen 15's inbuilt DITA framework and I would like to customize it by showing a Swing based form when Oxygen Author has been opened. This form will be used to set custom variables which can then be used later on. I am planning to do this using the Author API, specifically the AuthorExtensionStateListener interface (I saw a sample at " http://www.oxygenxml.com/doc/ug-author/index.html#topics/dg-author-extension..." in this regard). I presume the next step would be to register an implementation of AuthorListener (or extend the "AuthorListenerAdapter" class) within the activate method of the implementation of AuthorExtensionStateListener interface. My questions are as follows: a) Is this the best way to implement what I have in mind? b) There does not seem to be any Author window event which can be used to popup the form. I see others for doctypeChanged(), documentChanged etc here but nothing to record a opening-of-author event. I feel like I am missing something here and would greatly appreciate some help. If there is a better way to do this, I am all ears. Just a note, I cannot use plugins since this has to work for people who use Oxygen Author standalone and those who use the Author plugin within eclipse. My current code structure something like this... File 1: public class ditaAuthorExtensionStateListener implements AuthorExtensionStateListener{ .... .... public void activated(...){ // Add author document listeners. ditaAuthorDocumentListener = new DitaAuthorListener(); authorAccess.getDocumentController().addAuthorListener(ditaAuthorDocumentListener); } File 2: public class DitaAuthorListener implements AuthorListener{ ..... ..... // I am stuck here since I do not find any method which is triggered on opening Oxygen Author. Thanks a bunch! Nathan
