Bug 393522

Description Karl Hönninger 2012-11-05 04:38:54 EST

The parent shell of a primary modal dialog is accessible. I would expect that the parent is inaccessible (which is the case for an application modal dialog).

I found this behaviour in version '2.0.0.20121001-1623' and in mode 'OperationMode.SWT_COMPATIBILITY'. 

Here is a short snippet to reproduce this:



package org.openxma.rwt.launch;

import org.eclipse.rap.rwt.lifecycle.IEntryPoint;

public class RWTTest implements IEntryPoint {

	public int createUI() {
		
		Display display = new Display();
		final Shell shell = new Shell(display);
		shell.setText("Parent");
		shell.setSize(500,400);		
		shell.setLayout(new FillLayout(SWT.VERTICAL));

		/* primary modal shell */
		Button primaryModalButton = new Button(shell, SWT.PUSH);
		primaryModalButton.setText("Open primary modal shell");		
		primaryModalButton.addSelectionListener(new SelectionAdapter() {
			public void widgetSelected(SelectionEvent arg0) {
				Shell primaryModalShell = new Shell(shell, SWT.PRIMARY_MODAL | SWT.TITLE | SWT.CLOSE);
				primaryModalShell.setText("Primary modal");
				primaryModalShell.open();
				eventLoop(primaryModalShell);
			}
		});
		/* application modal shell */
		Button applicationModalButton = new Button(shell, SWT.PUSH);
		applicationModalButton.setText("Open application modal shell");
		applicationModalButton.addSelectionListener(new SelectionAdapter() {
			public void widgetSelected(SelectionEvent arg0) {
				Shell applicationModalShell = new Shell(shell, SWT.APPLICATION_MODAL | SWT.TITLE | SWT.CLOSE);
				applicationModalShell.setText("Application modal");
				applicationModalShell.open();
				eventLoop(applicationModalShell);
			}
		});

        /* open parent shell */
		shell.open();
		eventLoop(shell);
		return 0;
	}

	protected void eventLoop(Shell shell) {
		Display display = shell.getDisplay();
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch()) {
				display.sleep();
			}
		}
	}
}
