Description Filippo Maguolo 2012-03-18 08:50:49 UTC
Implementation of XUIElementFactory Java UNO API component
provide only "Frame" property but not "ParentWindow" (instead OpenOffice that works correctly).

Sample code:

public XUIElement createUIElement(String url, PropertyValue[] properties) 
     throws NoSuchElementException, IllegalArgumentException 

        try {
            if (!url.startsWith("private:resource/toolpanel/com.example.xtoolpanel")) {
                throw new NoSuchElementException(url);

            // retrieve the parent window and frame
            XWindow xParentWindow = null;
            XFrame frame = null;
            for (int i = 0; i < properties.length; i++) {
                PropertyValue propertyValue = properties[i];
                if (propertyValue.Name.equals("ParentWindow")) {
                    xParentWindow = UnoRuntime.queryInterface(XWindow.class, propertyValue.Value);
                } else if (propertyValue.Name.equals("Frame")) {
                    frame = UnoRuntime.queryInterface(XFrame.class, propertyValue.Value);

            if (xParentWindow == null) {
                throw new IllegalArgumentException("No parent window or frame provided in the creation arguments. Cannot create tool panel.");

            /// create the panel
            XUIElement xUIElement = new AddInPanel(m_xContext, frame, xParentWindow);
            return xUIElement;

        } catch (Exception ex) {
        return null;

Stephan, Michael - Advice here?
Comment 2 Michael Stahl (CIB) 2013-11-18 21:11:48 UTC
is the problem that there is no "ParentWindow" property in "properties"
or is there one and it is 0?

there's a whole bunch of places calling createUIElement, and i wonder which
of these would be the culprit...

framework/source/layoutmanager/layoutmanager.cxx:        xUIElement = m_xUIEleme
ntFactoryManager->createUIElement( aName, aPropSeq );
framework/source/layoutmanager/toolbarlayoutmanager.cxx:            xUIElement =
 xUIElementFactory->createUIElement( aAddonToolBarName, aPropSeq );
framework/source/layoutmanager/toolbarlayoutmanager.cxx:            xUIElement =
 xUIElementFactory->createUIElement( aName, aPropSeq );
framework/source/uifactory/uielementfactorymanager.cxx:            return xUIEle
mentFactory->createUIElement( ResourceURL, Args );
sfx2/source/dialog/taskpane.cxx:                xFactory->createUIElement( m_sResourceURL, aCreationArgs.getPropertyValues() ),
sfx2/source/sidebar/SidebarController.cxx:            xUIElementFactory->createUIElement(
sfx2/source/toolbox/tbxitem.cxx:            xUIElement = xUIElementFactory->createUIElement( rSubToolBarResName, aPropSeq );

... so these do not even attempt to add a "ParentWindow":

Comment 3 Caolán McNamara 2013-11-21 15:09:53 UTC
I sort of suspect that this is something based on one of the sdk examples. e.g. sdk/examples/python/toolpanel and so its probably the sfx2/source/dialog/taskpane.cxx thing (maybe)

But I'm not sure how that toolpanel example is supposed to work, i.e. if I build it and install it in LibreOffice 4.1 or Apache OpenOffice 4.1 then I don't see any UI thing to view that example.

I think we need something we can reproduce the reported problem with and info as to what version of OpenOffice it does work in
