Attach my action to F5 / Update

Question

I am writing a plugin for Eclipse and I would like to attach one of my actions to the Eclipse F5 / Refresh event.

Can anyone help me? Thank!

Answer 1

You can connect the IExecutionListener to the ICommandService. You will receive a notification of all completed commands. You can find the required command identifier (in this case org.eclipse.ui.file.refresh) and perform your operation

Answer 2

I assume you are writing this for Eclipse Helios (3.6).

In the Eclipse Help in the Platform Plugin Developer's Guide → Programmers Guide → Advanced Resource Concepts → Update Providers, there is an extension point.

org.eclipse.core.resources.refreshProviders

RefreshProvider, .
