Programmatically close a Java file? [message #1065168]

When several java files are open in the Java editor and a user deletes one of these files in the Package Explorer, "Eclipse" removes the deleted java file from the java editor. How can I do this programmatically?

Thank you for your help.

(P.S. I posted a similar question the Newcomers forum. I hope that it is not too redundant to ask again here.)

Do you want an editor you've implemented yourself to behave this way?
It's generally done by using a workspace listener in your editor:

ResourcesPlugin.getWorkspace().addResourceChangeListener(resourceChangeListener,
IResourceChangeEvent.POST_CHANGE);

Hi Ed,

Yes, I've extended org.eclipse.ui.editors.text.TextEditor.

Thank you for your help.

In EMF's generated editors we use a listener. You could look at the
source code:
