[news.eclipse.platform.swt] Calling Dialog from Thread

[reginald.johnson@xxxxxxxxx (Reginald Johnson)]

Hello,
 I have a dialog that I am calling from a thread.  The class itself 
extends Thread.  I am calling the dialog from that class like so:

//dislay the validation dialog
dspDisplay.syncExec(new Runnable() {
	public void run() {
		if (dspDisplay.isDisposed()){
			  return;
	        DlgValidateFile dlgValidateFile = new DlgValidateFile(sShell);
		dlgValidateFile.Open(sShell, alBadSessionIDs);
	}
});

Unfortunately, the dialog isn't responding to any events once it is 
opened.  I've successfully invoked a messagebox using similar code just 
prior to this call.  As far as I can tell there shouldn't be a difference. 
The code for the dialog is below.  I'd appreciate any help in figuring 
out why the dialog isn't responding.

public class DlgValidateFile extends Dialog {
	private ArrayList alValidatorWidgets = new ArrayList();
	
	public DlgValidateFile(Shell parent) {
		super(parent);
		// TODO Auto-generated constructor stub
	}

	private Shell shDlgValidator = null;  //  
@jve:decl-index=0:visual-constraint="70,72"
	private Button cmdClose = null;

	/**
	 * This method initializes shDlgValidator	
	 *
	 */
	private void createShDlgValidator(ArrayList alBadSessionIDs) {
		GridData gridData = new GridData();
		gridData.widthHint = 100;
		gridData.horizontalAlignment = org.eclipse.swt.layout.GridData.CENTER;
		gridData.grabExcessHorizontalSpace = true;
		shDlgValidator = new Shell(SWT.DIALOG_TRIM);
		shDlgValidator.setLayout(new GridLayout());
		shDlgValidator.setText("Edit Data File");
		shDlgValidator.setSize(new Point(375, 200));
		
		//create custom widgets
		for(int iCounter=0; iCounter< alBadSessionIDs.size(); iCounter++){
			String strWidgetValidator = "widValidator" + String.valueOf(iCounter);
			//add widget to list
			WidgetValidator widValidator = new WidgetValidator(shDlgValidator, 
SWT.NONE);
			widValidator.SetLabel((String)alBadSessionIDs.get(iCounter));
			alValidatorWidgets.add(widValidator);
		}
		
		cmdClose = new Button(shDlgValidator, SWT.NONE);
		cmdClose.setText("&Close");
		cmdClose.setLayoutData(gridData);
		cmdClose.addSelectionListener(new 
org.eclipse.swt.events.SelectionAdapter() {
			public void widgetSelected(org.eclipse.swt.events.SelectionEvent e) {
				shDlgValidator.dispose();
			}
		});
	}
	
	/************************************
	 * 
	 * @param parent
	 */public int Open(Shell parent, ArrayList alBadSessionIDs){
		createShDlgValidator(alBadSessionIDs);
		Display dspDisplay = parent.getDisplay();
		Rectangle parentRect = this.getParent().getBounds();
		int x = (int)((parentRect.width + parentRect.x)/2);
		int y = (int)((parentRect.height + parentRect.y)/2);
		
		shDlgValidator.setBounds(new Rectangle(x, y, 
shDlgValidator.getBounds().width, (alBadSessionIDs.size()*40)+100));
		
		shDlgValidator.open();
		dspDisplay = parent.getDisplay();
		while (!shDlgValidator.isDisposed()) {
		  if (!dspDisplay.readAndDispatch())
		    dspDisplay.sleep();
		}
		return 0;

	}
