Is there any quick way of hiding file's extension displayed by Common Navigator Framework, without implementing both content provider and label provider.
What I would like to do is to cut off the extension of the file when displayed by CommonViewer - fro example I would like to CV display "file" instead of file.exe.

You will need to implement a label provider to actually hide the labels and then you can delegate the rest of the work to the existing label provider. You can use the existing content provider.

You will need a new Navigator Content Extension that overrides the existing one.

Thanks for the reply,
When you say I should provide new 'Navigator Content Extension' you mean define new extension 'org.eclipse.ui.navigator.navigatorContent' and its child 'navigatorContent' and then define new content provider and label provider plus all the other stuff (name, priority...)?.
Well, CNF is using as its content provider the 'org.eclipse.ui.internal.navigator.resources.workbench.Resou rceExtensionContentProvider' class and as label provider it is using a 'org.eclipse.ui.internal.navigator.resources.workbench.Resou rceExtensionLabelProvider'.
My dilemma now is that if I define new 'org.eclipse.ui.navigator.navigatorContent' with 'navigatorContent' I will have to specify as a content provider the internal Eclipse class 'org.eclipse.ui.internal.navigator.resources.workbench.Resou rceExtensionContentProvider' to use it as a default implementation for content provider which to me sounds a bit like a hack.
Providing new label provider is not a problem all I need to do is to derive my label provider from 'WorkbenchLabelProvider' and specify it in 'labelProvider' in 'navigatorContent'.
Is there any cleaner way of providing default content provider without specifying the 'org.eclipse.ui.internal.navigator.resources.workbench.Resou rceExtensionContentProvider'?
Sorry if I did not understand your answer,
Cheers,
Janusz

You understood the answer perfectly correctly and you are right it's a bit of a hack since you are referencing an internal class.

That's the way you have to do it for now, but it brings up an interesting point for which I invite you to file an enhancement request.

I think it would be interesting to be able to override an NCE but to use that' NCE's content provider rather than provider your own.

Can you file an enhancement request against Platform, UI, Common Navigator?
