How to programatically select a node from the outline? [message #1099231]

Hello Again Smile

I have a button in the upper right corner of my XML Editor that compares the opened XML file with another one based on a specific set of criteria.

The action then displays a Dialog with the items that have problems or needs to be revised. These items are displayed in a ListViewer.

Now I want user to double click an item in the list, and the tool highlights or selects the appropriate Node for him. Is there a way to highlight or select a Node from the Outline on the left programatically?

Thnx

In your action, you have access to the context Sapphire Part. From there...

MasterDetailsEditorPagePart page = part.nearest( MasterDetailsEditorPagePart.class );
page.outline().setSelectedNode( ... );

page.outline().setSelectedNode( ... );

This method needs a "MasterDetailsContentNode" object. How to get that from an "IModelElement" object?

UPDATE:

I found it Smile

using:

page.outline().getRoot().findNodeByModelElement(element);

ANOTHER UPDATE:

Method "findNodeByModelElement" doesn't search the entire tree. It searches only among children nodes of the caller node.

It sounds like you found the API that you needed. If you call findNodeByModelElement on the root node, you will search the entire tree.

Well .. in my case it didn't!
It only searched among the first level children!

Are you certain? You may want to step through the invocation in your scenario. The method in question is definitely recursive...

Sorry, my fault Smile

You're correct
