Eclipse Plugin Development : Small nuggets

Small snuggets for eclipse plugin development are small snippets of code useful in eclipse plugin development.

In eclipse windows that you see contains pages . Each of this page hosts a view or an editor .
Generally these editors are not hosted directly but indirectly via references ( aka proxies to the actual editor / views )

So to get reference to the actual editors / views from the pages use code like this :

IWorkbenchPage page = getPage();
IEditorReference[] editors = page.getEditorReferences();

Once you have the references you can get the actual hosted editor / view.

Editors in eclipse implement IEditorPart , so to get an editor some thing like this would work:

IEditorPart editor = editor.getEditor(true);

To reveal IJavaElement in the editor ( basically any java method , entity ) using JDT ( eclipse for java development is based on it )

JavaUI.revealInEditor(part , javaElement);

To add an action (aka tool bar item ) in the toolbar for your view something like this would work :

IActionBars actionBars = view.getViewSite().getActionBars();
IToolBarManager manager = actionBars.getToolBarManager();
manager.add(new MyToolBarItem());
