I'm not sure if this is the correct forum for this question. I thought about the JFace forum, but these question seems mostly an integration question.
I am an eclipse newbie. I have a long term goal which is to add my own annotations to the java editor: a bit like FindBugs. I want my own static code analysers, and to be able to add markers/annotations to resources.
So I have read a lot of excellent documentation, and undertaken a load of tutorials. The most helpful was probably www.ibm.com/developerworks/opensource/tutorials/os-ecl-commplgin2/section9.html. A lot of the Lars Vogel documents have been useful too. I can now make TextEditors with syntax highlighters. I am however struggling with the best approach for adding annotations.
I understand roughly how to do this: the text editor has a DocumentProvider. The DocumentProvider has an AnnotationModel. It is possible to add annotations to the annotation model.
My question is "where do I put this code" specifically the code that scans the text in the editor and updates the annotation model. It seems clear that this should be in response to a listener...but which one?
I have tried a ResourceChangeListener. This seems to only fire on a save option, rather than when text is typed. In addition I don't know how to get the editor from the resource. ("The" editor is probably a misnomer as presumably the resource can be open in multiple editors). I can find the current editor via IWorkbenchWindow activeWorkbenchWindow = workbench.getActiveWorkbenchWindow().getActivePage().getActiveEditor(), but this seems the wrong approach, as I want to update all relevant annotation models.
I have tried adding an ElementStateListener to the text editor. None of the events seem to be the one I want.
I've looked at DamageRepairers...these seem to nearly be what I want, except that long term I want to tie into the JavaEditor, so I don't want to change the default DamageRepair.
Thanks for all the help
