This shows that closing is not done synchronously and so it is prevented by the dialog box that is opened before the view can be exchanged. Of course you can't close a view that contains a modal dialog! Obviously there is an additional asynchronity in the code that executes the ClosePreview command, it's not the dispatcher that works asynchronously. I had a look into the Writer code and indeed this is what happens. The closing of the preview is done by creating a new view and replacing the preview in the same window by it, and this is done asynchronously. I assume this is done to protect against possible crashes in case execution of the dispatch calls is requested by an object inside the view that can't cope with being killed itself before the call returns. So at least currently you can't do anything against it, except writing an issue of course asking the Writer developers for switching to a synchronous exchange of the View (though I don't know if this is feasible).

Hi Mathias,
What means without success? What exactly did you do and what exactly
happened?
that means, the preview is not closed, if i open a message box directly after
the
excecuteDispatch(), it does not matter if i use the SynchronMode or not ...
the message box is shown in preview mode, after closing it, preview mode is
still active ...
without showMessageBox() the preview is closed ...
here is a snippet of my code:
PropertyValue[] xProps = new PropertyValue[1];
xProps[0] = new PropertyValue();
xProps[0].Name = SynchronMode;
xProps[0].Value = Boolean.TRUE;
executeDispatch(getModel().getCurrentController().getFrame(),
.uno:ClosePreview, xProps);
showMessageBox();
public Object executeDispatch(XFrame xFrame, String sUrl, PropertyValue
xProp[]) {
Object dispatchHelper = null;
try {
dispatchHelper = xComponentContext.getServiceManager()
.createInstanceWithContext(com.sun.star.frame.DispatchHelper,
xComponentContext);
} catch (Exception e) {
return null;
}
XDispatchHelper xDispatch = (XDispatchHelper) UnoRuntime
.queryInterface(XDispatchHelper.class, dispatchHelper);
XDispatchProvider xProvider = (XDispatchProvider) UnoRuntime
.queryInterface(XDispatchProvider.class, xFrame);
Object oDispatch = xDispatch.executeDispatch(xProvider, sUrl, , 0,
xProp);
return oDispatch;
}
public void showMessageBox() {
XWindow xParent = null;
XFrame xFrame = xController.getFrame();
XToolkit xToolkit = null;
if (xFrame != null)
xParent = xFrame.getContainerWindow();
try {
xToolkit = (XToolkit) UnoRuntime.queryInterface(XToolkit.class,
xComponentContext.getServiceManager()
.createInstanceWithContext(
com.sun.star.awt.Toolkit,
xComponentContext));
} catch (Exception e) {
e.printStackTrace();
}

Closing a view synchronously is a little bit risky. If the code is executed from a call stack that was started somewhere inside a VCL resource (e.g. a toolbar) it *could* lead to a crash. So you have to try out if it works.

Oliver Brinzing wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, at the moment I am trying to convert some of my basic macros into a java component :-) but get stuck with the following problem: dispatching .uno:ClosePreview from java seems not to work in all cases, if I open a message box directly after the xDispatch.executeDispatch the message box will be displayed in the preview mode ... after closing the message box, we are still in the preview mode ... the dispatch got lost ??? I think this i caused due to the async behaviour of the dispatching framwork ... I also tried xNotifyingDispatcher.dispatchWithNotification() without success ... :-( In Basic I used the following: Function ClosePreview() Dim oView as Object Dim oDispatcher as Object Dim mNoArgs() Dim i as Integer oView = ThisComponent.getCurrentController() If Not hasUnoInterfaces(oView, com.sun.star.sheet.XSpreadsheetView) Then oDispatcher = createUnoService(com.sun.star.frame.DispatchHelper) oDispatcher.executeDispatch(ThisComponent.getCurrentController().Frame, .uno:ClosePreview, , 0, mNoArgs()) While Not hasUnoInterfaces(oView, com.sun.star.sheet.XSpreadsheetView) and i 10 Wait(0) oView = ThisComponent.getCurrentController() i = i + 1 Wend EndIf MsgBox Hello World... CStr(i) End Function Any hints ? Using of the interface XNotifyingDispatch does not make the dispatch itself synchron ... it guarantees only, that the given listener will be called. Becausde normal XStatusListener used for a XDispatch call are not guaranteed to be used ! If you wish to force a synchronous execution of your dispatch you should try the argument Asynchron as [bool] with a valud false. But note: Forcing the synchron mode for an asnychronous operation can make trouble. E.g. closing of such preview will destroy resources, which are used by your own java code. In such case Disposed- or RuntimeExcception can occure, which of course must be handled by your code. You have to make sure that all references to these preview was released by yourself /Hint: GarbageCollector .-) Oliver - -- Regards Andreas - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
