How to refresh my CNF for custom object model? [message #667144]

Hi,

I am using Eclipse 3.6. I have custom object model. I followed some tutorial to use CNF with content/label providers. So far, it works as the model is displayed on the tree viewer in CNF, with initial data model.

My model is extending the modelObject (PropertyChangeSupport) and i have bind the class attributes and UI properties in the wizard page. So changes in the wizard page UI is reflected on the model.

However, my wizard allows user to add new object into the model. How do I refresh the treeviewer once he/she has added it?

do i add listener in my MyCommonNavigator (extends CommonNavigator) ? which listeners?

Thanks.
Andy

Have a look at the ResourceExtensionContentProvider class in org.eclipse.ui.navigator.resources

This makes the necessary viewer calls to update things when the model has changed.

Essentially you just update the viewer (CommonViewer) just like any other JFace Viewer. You can get the viewer using CommonNagivator.getCommonViewer()
