Plug-in or rcp - Using ViewPart

Question

I'm programming a eclipse plug-in and I need to do a particular thing.
I have a action toolbar controlled by the class that implement IWorkbenchWindowActionDelegate; this toolbar have 1 button.
Also I have one view that implement ViewPart; this view have one text field and one button.
The problems is:
When I do a click the button in the toolbar I must show the view and wait until I do a click to button in the view and acquire the value of the textfild.
In other words, The View must work like modal dialog.
I am able to show the view but I'm not able to wait and retrieve the value of the textfild in the view.
How can i do this? It's very important to me to do this.
Help me please!!!!!
Code of class that manage the action toolbar:
public class Bottoni implements IWorkbenchWindowActionDelegate {
     public boolean aggc=false;
     public void dispose() {
          // TODO Auto-generated method stub
     public void init(IWorkbenchWindow window) {
     public void run(IAction action) {
          if (action.getId().equals("bott_agg")){
               try {
              IViewPart p;
                    p = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().showView("traduttorealan.views.AggiornamentoKeyword");
               AggiornamentoKeyword a=(AggiornamentoKeyword) p.getAdapter(AggiornamentoKeyword.class);
               //AggiornamentoKeyword a=(AggiornamentoKeyword)p.getView(true);
               Problem
               -I have showed the view
               but now How can I wait that the user do a click to a buttun in the View and retrieve the value of textfild?
               String str=a.getpr();  //this is only an experiment
               } catch (PartInitException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
     public void selectionChanged(IAction action, ISelection selection) {
          // TODO Auto-generated method stub
Code of class that manage the view:
public class AggiornamentoKeyword extends ViewPart {
     String pr;
      * The constructor.
     public AggiornamentoKeyword() {
// the following method is only an experiment
     public synchronized String getpr(){
          return pr;
      * This is a callback that will allow us
      * to create the viewer and initialize it.
     public void createPartControl(Composite parent) {
          GridLayout layout=new GridLayout();
          layout.numColumns=8;
          parent.setLayout(layout);
          insKeyLab = new Label(parent, SWT.NULL);
          insKeyLab.setText("Nuova Keyword:");
          insKey = new Text(parent, SWT.BORDER);
          insKey.setEditable(true);
          GridData gridData = new GridData(GridData.FILL_HORIZONTAL);
          gridData.horizontalSpan = 5;
          insKey.setLayoutData(gridData);
          aggkey=new Button(parent, SWT.PUSH);
          aggkey.setText("aggiorna");
          aggkey.addSelectionListener(new SelectionAdapter() {
               public void widgetSelected(SelectionEvent event) {
                         pr=insKey.getText();
          annullaagg=new Button(parent, SWT.PUSH);
          annullaagg.setText("annulla");
          keyListLab = new Label(parent, SWT.NULL);
          keyListLab.setText("Lista Keyword presenti:");
          gridData = new GridData(GridData.FILL_HORIZONTAL);
          gridData.horizontalSpan = 10;
          keyListLab.setLayoutData(gridData);
          keyList = new Text(parent, SWT.MULTI | SWT.V_SCROLL);
          keyList.setEditable(true);
          GridData gridDatal = new GridData(GridData.FILL_BOTH);
          gridDatal.verticalSpan=4;
          gridDatal.horizontalSpan = 10;
          keyList.setLayoutData(gridDatal);
     private void showMessage(String message) {
//          MessageDialog.openInformation(
//               viewer.getControl().getShell(),
//               "AggiornamentoKeyword",
//               message);
      * Passing the focus request to the viewer's control.
     public void setFocus() {
//          viewer.getControl().setFocus();
}

You'll be very lucky to get an answer here, hardly anyone uses Eclipse RCP. Far and away the best place for RCP help are the Eclipse.org newsgroups
