Bug 335954

Description Markus Keller 2011-02-01 08:38:24 EST

HEAD, happens since at least 3.2.2 (didn't check further back)

When I close a shell that contains a browser widget by pressing Alt+4, a beep is played somewhere in IOleInPlaceObject#InPlaceDeactivate().

In the SDK, this happens with the "Help > Help Contents" window, and it also happens when I detach the Javadoc view and then close it via Alt+F4. Does not happen when I close the child shell by other means.

package snip;

import org.eclipse.swt.*;
import org.eclipse.swt.browser.*;
import org.eclipse.swt.events.*;
import org.eclipse.swt.graphics.*;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.widgets.*;

public class SnippetBrowserAltF4 {
    public static void main(String[] args) {
        Display display= new Display();
        final Shell shell= new Shell(display);
        shell.setSize(320, 200);
        shell.setLayout(new GridLayout());
        
        Button button= new Button(shell, SWT.PUSH);
        button.setText("&Open");
        button.addSelectionListener(new SelectionAdapter() {
            public void widgetSelected(SelectionEvent e) {
                Shell shell2= new Shell(shell);
                shell2.setLayout(new FillLayout());
                Browser browser= new Browser(shell2, SWT.NONE);
                browser.setText("Close with <b>Alt+F4</b> => beeps.");
                
                Rectangle bounds= shell.getBounds();
                bounds.x += 20;
                bounds.y += 60;
                shell2.setBounds(bounds);
                shell2.open();
            }
        });
        
        shell.open();

        while (!shell.isDisposed()) {
            if (!display.readAndDispatch())
                display.sleep();
        }
        display.dispose();
    }
}
