[newbie] Getting the selected resource in a popup menu action [message #251304]

It seems like every single pop-up menu action in the documentation always
creates a dialog box. But what I would like to do is do something with the
file that I just right-clicked on to make that pop-up menu show up in the
first place.

How do I do this? Is there a method called getSelectedResource() or
something? Thanks.

If your action was contributed through the plugin.xml, then it must
implement IActionDelegate. If so, then it is told what was selected via
the setSelection method.

I've checked the API and i see no existence of setSelection method in an
IActionDelegate

Would you mind being a little more detailed in how to do it? This is how i
currently do it:

package MenuSample.popup.actions;

import org.eclipse.jface.action.IAction;

import org.eclipse.jface.dialogs.MessageDialog;

import org.eclipse.jface.viewers.ISelection;

import org.eclipse.swt.widgets.Shell;

import org.eclipse.ui.IObjectActionDelegate;

import org.eclipse.ui.IWorkbenchPart;

import org.eclipse.ui.IWorkbenchWindow;

import org.eclipse.jface.viewers.IStructuredSelection;

import org.eclipse.core.resources.IResource;

public class NewAction implements IObjectActionDelegate {

private String title;

private IResource resource;

private IStructuredSelection sSelection;

private IWorkbenchPart part;

private IWorkbenchWindow window;

/**

* Constructor for Action1.

*/

public NewAction() {

super();

}

/**

* @see IObjectActionDelegate#setActivePart(IAction, IWorkbenchPart)

*/

public void setActivePart(IAction action, IWorkbenchPart targetPart) {

part = targetPart;

}

/**

* @see IActionDelegate#run(IAction)

*/

public void run(IAction action) {

sSelection = (IStructuredSelection)
part.getSite().getSelectionProvider().getSelection();

resource = (IResource) sSelection.getFirstElement();

title = resource.getName();

Shell shell = new Shell();

MessageDialog.openInformation(

shell,

"MenuSample Plug-in",

title);

}

It's called selectionChanged(Selection). It is called when the selection
has changed.
