Hello, all!

I am developing an editor for some type of files (for example .xxx) and my editor allows user to edit all files of some package in one editor tab.

When user opens the second .xxx file in the same package Eclipse creates a new editor for it. But I need not to open new tab, but set focus on existing one.

How may I do it?

I tried to do it in init() method but it does not works.

Also I tried to do like this:

Activator.getDefault().getWorkbench().getActiveWorkbenchWindow().getActivePage().closeEditor(this, false)


in methods init() or createPartControl(): tab closes, but I Eclipse catches an exception and sets focus on the rightest tab in the list.

java.lang.RuntimeException: WARNING: Blocked recursive attempt to close part com.doksoft.propeditor.PropEditorForEclipse while still in the middle of activating it
	at org.eclipse.ui.internal.WorkbenchPage.closeEditors(WorkbenchPage.java:1282)
	at org.eclipse.ui.internal.WorkbenchPage.closeEditor(WorkbenchPage.java:1411)
...


Can you write full openEditor() call and tell me in what method am I to insert it, please?

You will have to extend AbstractTextSearchViewPage and override
showMatch(Match match, int offset, int length, boolean activate) method.

use extension point "org.eclipse.search.searchResultViewPages" in plugin.xml.

My guess is that you'll have to specify a matchingStrategy to your
editor extension.
