| Common Navigator showing expanded folders [message #334395] |

I am contributing to a common navigator from my plugin.xml
I would like to show different icons for an open "folder" and closed
"folder". By "folder" I mean things that have children as specified in the
content provider.
In the navigatorContent, I specify a labelProvider.
I thought that in my label provider's getImage() I could to check the
expanded state of the tree.
However, the label provider does not know about the tree that it is
connected to.
If I programmatically instanciate the label provider, I can pass the tree
to the constructor, however, when I am configuring it from the plugin.xml,
I assume the default constructor (i.e. no parameters) is used and so I
cannot pass in the tree.
Question: How do I show a different icon for open and closed folders, when
contributing to a common navigator using the plugin.xml file?
Thank you for your help

You can get the CommonViewer from the CommonNavigator.getCommonViewer().
This is a normal JFace TreeViewer, from there you can get to the tree.
You can get your CommonNavigator instance by view Id if necessary.

Try this:
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().findViewReference().getView(false)
This gets the part only if it has been actually created, so you should
not get those errors of it being in the middle of creation.
