Creating a new customized Outline-View [message #550691]

Hi,

I want to create a new view that is very similar to the current Outline-View. The new Outline-View has to list some special contents of a CompilationUnit. I want the view to be updated if the current CompilationUnit in the JavaEditor is changed or exchanged by changing the current editor tab.
How can I do that? I searched through the JavaEditor code and recognized that a JavaOutlinePage is created by the JavaEditor. So I will have to subclass JavaEditor and rewrite some Methods that the Editor is able to create the new Outline-Page. How can I tell the Plugin to use the new JavaEditor?

I hope that I could explain what I want to do.
Thanks in advance.

Jochen

You don't need to subclass JavaEditor. You can update your view (input)
via part listener and listen for changes to the CU using an
org.eclipse.jdt.core.IElementChangedListener.

Thanks for your reply. I think this will solve the problem with updating the input for my view.
But I'd like to have another nice feature that the Outline-View offers. You can doubleclick on an element from the Outline-View and the JavaEditor automatically highlights the appropriate source code. It would also be nice to have this feature the other way around. Is something like that possible? Or will I have to create my own editor to do things like that?

Thanks again.

Jochen

@see ITextEditor#setHighlightRange(int, int, boolean)
@see ITextEditor#showHighlightRangeOnly(boolean)

Thanks again for your help.

For everyone who is interested:
I solved the problem of refreshing my views input after a change in the java editor. A very good link is: http://pookzilla.net/wp/2006/10/link-to-editor/
