Subject [jira] [Commented] (UIMA-2252) Migrate TextMarker visualization to CAS Editor
Date Thu, 13 Oct 2011 11:41:16 GMT

    [ https://issues.apache.org/jira/browse/UIMA-2252?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13126496#comment-13126496

Joern Kottmann commented on UIMA-2252:
--------------------------------------

The Cas Editor is using ISelectionProvider and ISelectionListener to synchronize selections
between different views. You also need to use this.

To register a selection listener in a view you would do a call like this:
getSite().getPage().addSelectionListener(...);

And to register the selection provider:
getSite().setSelectionProvider(...);

In the Cas Editor views usually a JFace Viewer is registered as the selection provider,
e.g. a list, table, tree, etc.

The viewer contains usually your element objects, if this is not a FeatureStructure,
you should return the FeatureStructure via getAdapter.
