prevent document closing

Hi,

How can I prevent a document from closing? I've figured out
how to do it 
for the frame by adding a CloseListener and throwing a 
CloseVetoException in queryClosing, but this does not seem
to work for 
the internal document.

It works the same way. The document will not be closed
(=destroyed)
then. I assume that you also want to prevent the document
windows from
being closed. This is only possible by registering your
listener at the
corresponding frames.

Can you tell me why this code doesn't work then:

public void someMethod() {
            unoidl.com.sun.star.uno.XComponentContext
localContext = 
uno.util.Bootstrap.bootstrap();
           unoidl.com.sun.star.lang.XMultiServiceFactory 
multiServiceFactory =
(unoidl.com.sun.star.lang.XMultiServiceFactory) 
localContext.getServiceManager();

   
            XComponentLoader componentLoader =

               
(XComponentLoader)multiServiceFactory.createInstance(

                                     
"com.sun.star.frame.Desktop");

            //Create a new blank writer document using our
component 
           
            //enable macros
            PropertyValue[] args = new PropertyValue[1];
            args[0] = new PropertyValue();
            args[0].Name = "MacroExecutionMode";
            args[0].Value = new
Any(MacroExecMode.ALWAYS_EXECUTE_NO_WARN);
           
            XComponent xComponent =
componentLoader.loadComponentFromURL(
        
                "private:factory/swriter",
                "_blank", 0,      
                args
                );

  
         
            //get the document frame
            XFrame frame = 
((unoidl.com.sun.star.text.XTextDocument)xComponent).getCurr
entController().getFrame();
    
          //If i add the listener to the frame here, the
outer most 
frame is prevented from closing, but the user can still
click the 
internal document window's close button and the document
will close 
which is not the behavior I want
/*           XCloseBroadcaster xcb =
(XCloseBroadcaster)frame;
            xcb.addCloseListener(new CloseListener());*/

            //If i add the listener to the xcomponent, the
queryClosing 
method is fired when either the internal document's close
button or the 
frame's close button is clicked, but the document is not
prevented from 
closing    
        XCloseBroadcaster xc =
(XCloseBroadcaster)xComponent;            
            xc.addCloseListener(new CloseListener());

}

    public class CloseListener : XCloseListener {

          
            public void 
notifyClosing(unoidl.com.sun.star.lang.EventObject Source) {
              
            }

            public void 
queryClosing(unoidl.com.sun.star.lang.EventObject Source,
bool 
GetsOwnership) {
                throw new CloseVetoException();
            }

 

            public void
disposing(unoidl.com.sun.star.lang.EventObject 
Source) {
             
            }

         
        }

Well, in fact the frame isn't closed, so there is no reason
to ask your
listener for permission. There is only one frame object
involved, this
object and its window are controlled by the
"outer" (big) closer. The
"inner" closer (the smaller one) does not control
a frame it removes the
component inside the frame from the frame. This feature was
introduced
for the last frame (window) of OOo because it allows users
to keep OOo
in memory without keeping their last document open.

No, it should be: usually closing the document window would
also close
the document (means: destroy it) but this shouldn't happen
if you
register your listener and veto against closing. Of course
you can't
prevent the window from being closed here - in fact you
can't do it at
all as I have to admit.

So here's what you should see in the listener you have
registered at the
document (component):

- you get a queryClosing
- if you throw a CloseVetoException you shouldn't get any
further calls
- if you don't object you should get a closing() as well as
a
disposing() notification.

Best regards,
Mathias

So how do I prevent the inner document window from being
closed?

As I wrote already:

Sorry for the bad news.
