selectionchanged on CommonNavigator [message #326802]

I need to call my own action every time a project is selected in the navigator view - in-fact my own view extended from CommonNavigator. Can someone please suggest the best approach?

You can register a selection changed listener on the CommonViewer that's
associated with the CommonNavigator.

Just call getCommonViewer() on the CN.

I suppose then I would need to sub-class CommonNavigator (myNavigator->CommonNavigator) and reference that from my viewer extension instead...

<extension
point="org.eclipse.ui.views">
<view
class="myNavigator"
etc../>
</extension>

then I can register the selection changed listener in the constructor? The Eclipse documentation says CommonNavigator is not intended to be sub-classed!

no you don't need to subclass the CN, just get the viewer by calling
getCommonViewer() on the CN once it has been created.

(no worries with your XML, I get the idea)

You can obtain it by looking into the workbench the workbench window and
obtain the view by the name you gave it or its default name. The CN is
actually a view part. Once you obtain the view, cast it to get the the
getCommonViewer method.

PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().findView( "yourCNFViewName")

This works from nearly anywhere in the application. If the CN is always
around, stick it into a singleton that you know where to find easily but
I always dynamically get it.
