| Hook custom tree outline to package explorer [message #252439] |

Hello, I'd like to make a custom tree outline for XML files appear in the
package explorer for each file, just like the Java outline does for Java
files.
So far, I've used the "org.eclipse.ui.navigator.navigatorContent"
extension point, providing an ITreeContentProvider and an ILabelProvider.
The tree appears, but it doesn't reflect any changes in the file, not even
when I refresh the view.
I have the feeling that these providers are not enough, and am searching
for the minimal set of classes that implement the desired functionality in
JDT. However, as the project is rather big, I'm somewhat lost. Can someone
give me a good starting point?
Generally, I'd guess that the concept of reusing a TreeViewer based
ContentOutlinePage in the package explorer (and have these explorer views
interact with each respective file as outlines would) might be a huge
value-add for many projects. Is there a standard way to achieve this, or
maybe a detailed tutorial?
Thanks in advance!

I assume you are talking about the Project Explorer (aka Common
Navigator) and not the Package Explorer which can't be extended like this.

Yes, sorry. It's probably the Project Explorer, I was confusing the two.
Can I extend the Project Explorer / Common Navigator in the described
fashion?

Even in the Project Explorer, Java elements are updated in the tree, as
soon as they are changed in a Java editor, and on saving the file even
from a normal text editor. How is this done, i.e. which extension points
have to be used?
Thanks for your help!

Thanks to your introduction to the name "Common Navigator", I was now able
to find these blog postings to the org.eclipse.ui.examples.navigator
example, which is pretty much the minimal setup I was looking for:

The solution found in the sample code is to add an IResourceChangeListener
to the Workspace in the constructor of the ITreeContentProvider. No
extension point mechanisms are used for this.
Many thanks!
