Question

I am currently developing a plugin for eclipse that analyzes dependencies and references between projects within the Eclipse Workspace and displays them in its own View in a UML-like diagram.

To increase the usefulness of my plugin, I wish to add interactivity to the diagram by allowing users to open a project in the package explorer and if applicable open it in an editor by clicking on the graph displayed.

However, my problem is that while I know how to obtain a given selection from the package explorer, I have not been able to find a way to change the selection or simply open up a project in the package explorer programmatically.

Does anyone have a solution for this problem?

Answer 1

I have found the solution. Eclipse does offer direct access to the package explorer in org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart , but it is discouraged.

import org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart;

...

PackageExplorerPart part= PackageExplorerPart.getFromActivePerspective();
IResource resource =  /*any IResource to be selected in the explorer*/;

part.selectAndReveal(resource);

This will highlight whatever IResource resource is and expand the tree as necessary.
