Re: [jdt-ui-dev] How to call Javadoc view?

[Brian de Alwis <briandealwis@xxxxxxxxx>]

Hi Jan.  

I use the same mechanism in one of my tools (Ferret) and the Javadoc view correctly reacts to selections.

One thing you haven't shown is how you pump out your view's selections (i.e., calling your setSelection()).  If your viewers (say a JFace TreeViewer) is manipulating IJavaElements, you can actually just do:

	getSite().setSelectionProvider(myTreeViewer);
