Help on the Common Navigator Framework [message #496331]

Hello everybody,

I am trying to add a navigator to my RCP application. Should I do this with the Common Navigator Framework or is CNF only meant for developing plugin of Eclipse IDE ?

I have tried to follow this tutorial : http://scribbledideas.blogspot.com/2006/05/building-common-n avigator-based-viewer.html but it does not help me much. For example, where should I write my code piece for opening double-clicked resources in the view ?

Many thanks in advance,
Damien

The Common Navigator Framework is what you want.

Look at the documentation for it (it's in your Eclipse SDK help or at the link in my signature). It should have enough to get you started. It's designed to work both in the IDE and an RCP environment.

Thank you Francis,

I have gone a bit further with CNF since the last time, but I still have one blocking problem.

I have created a Navigator view with navigator contents and viewer content bindings as explained in http://scribbledideas.blogspot.com/2006/05/building-common-n avigator-based-viewer.html but when I create a new project from the context menu of the Navigator view of my RCP app, I get the following displayed: "no label provider for P/MyProject". I also have the same problem when the navigator is created from this extension wizard: http://blog.eclipse-tips.com/2008/06/easiest-way-to-create-c ommon-navigator.html.

Do you know what I am doing wrong ?

Thank you again,
Damien

What this means is that the no label provider associated with any navigatorContent extensions has returned a text value. You can turn on debug tracing in the CNF (in the tracing tab of your launch configuration), this will give you helpful messages. And you should set a breakpoint at your label provider's getText() and getStyledText() methods to see if they are being invoked. Make sure they return a non-null value.

It looks like this is happening with an IProject resource. Are you including the org.eclipse.ui.navigator.resources plugin? Do you intend to handle the processing of resources?

Yes I added the org.eclipse.ui.navigator.resources plugin in my dependencies, and included it in the target platform and launch configuration. I did not really intend to use this plugin at first, but I thought it was almost mandatory to have it in order to handle resources properly.

I am just surprised that there is no label provider associated by default with the IProject resource that I create from the navigator "New>Project" wizard.

I will try what you advise and let you know. Tank you for that.

The org.eclipse.ui.navigator.resources contains this part in it's NCE:

<navigatorContent
name="%resource.extension.name"
priority="low"
icon="$nl$/icons/full/eview16/resource_persp.gif"
activeByDefault="true"
contentProvider=" org.eclipse.ui.internal.navigator.resources.workbench.Resour ceExtensionContentProvider "
labelProvider=" org.eclipse.ui.internal.navigator.resources.workbench.Resour ceExtensionLabelProvider "
id="org.eclipse.ui.navigator.resourceContent">
<enablement>
<or>
<adapt type="org.eclipse.core.resources.IProject" />
<instanceof
value="org.eclipse.core.resources.IResource" />
</or>
</enablement>

So it does handle projects. You might want to set a breakpoint also on the ResourceExtensionLabelProvider above.
