I'm posting this to the dev mailing list as I'm not sure which project
specific lists I should be posting to. Let me know where to redirect this if
necessary.
I'm trying to display Open Office in a child window on Windows. I've tried
both the Hack and Legal approaches described in the 2.0 Developer's Guide,
section 6.1.7 Java Window Integration, Using the Window Handle (pages
417-418 in my copy). In both cases my code hangs:
a) in the createSystemChild call using the Legal approach.
b) in the createWindow call using the Hack approach.
My code is written in C++ using Visual Studio 2005 on Windows XP Pro, SP2,
fully updated. I'm running Open Office 2.0.1rc5 with the SDK version
2.0.0rc2. I have working code that can bootstrap the local Open Office,
open, save and close a document, add listeners and keyhandlers, and shutdown
gracefully. The child window problem is the only one I haven't been able to
solve.
I'm aware of the ActiveX control, so_activex.dll, that is included in the OO
install. It doesn't provide the functionality that I need. I'm also aware
that the source code for this control is included with the SDK in <SDK
Root>\examples\OLE\activex. I've even built the control from the source code
and tested it to confirm that it still works when built with VS 2005.
I've used Spy++ to analyze the windows created by the working OO ActiveX
control, and those created by my ActiveX control up to the moment that the
call hangs. Spy++ shows that my control creates the same child window of
window class SALTMPSUBFRAME that the OO control creates. Everything in the
Spy++ Window Properties looks the same except for the fact that the Window
Proc on the General tab shows as unavailable. I assume that this is an
indication that the window is still in limbo because the call hung. The OO
QuickStarter icon is unresponsive while the call is hung.
There are differences between the code listed below and the example in the
Dev guide:
a) I use cppu:bootstrap() to get my initial context. This connects to OO
through a named pipe. All the Dev guide examples connect using sockets.
b) I use XMultiComponentFactory::createInstanceWithContext instead of
XMultiServiceFactory::createInstance. This follows the recommendations in
the Dev Guide section 3.3.2 Service Manager and Component Context.
Bootstrap code:
Reference<XComponentContext> xLocalContext;
Reference<XMultiComponentFactory> xServiceManager;
if (!xLocalContext.is())
xLocalContext = bootstrap();
if (!xServiceManager.is())
xServiceManager = xLocalContext->getServiceManager();
Child window code: HWND hwnd is passed in from the control.
Reference<XToolkit>
xToolkit(xServiceManager->createInstanceWithContext(
OUString::createFromAscii("com.sun.star.awt.Toolkit"),
xLocalContext),
UNO_QUERY);
Either this:
// Legal solution from section 6.1.7 of the Dev Guide (pg. 417-418)
Reference<XSystemChildFactory> xFac(xToolkit, UNO_QUERY);
Any anyHwnd;
sal_Int32 int32Hwnd = (long)hwnd;
anyHwnd <<= int32Hwnd;
sal_uInt8 processID[16];
rtl_getGlobalProcessId(processID);
Reference<XWindowPeer> xPeer = xFac->createSystemChild(anyHwnd,
Sequence<sal_Int8>((sal_Int8*)processID, 16),
com::sun::star::lang::SystemDependent::SYSTEM_WIN32);
// End Legal Solution
or this:
// Hack
// Note that VTOOWindowPeer is an implementation of XWindowPeer and
XSystemDependentWindowPeer
// that returns the window handle to createWindow.
Reference<XWindowPeer> xParentPeer = new VTOOWindowPeer(hwnd);
WindowDescriptor aDescriptor;
aDescriptor.Type = WindowClass::WindowClass_TOP;
aDescriptor.WindowServiceName =
OUString::createFromAscii("workwindow");
aDescriptor.ParentIndex = 1;
aDescriptor.Parent = xParentPeer;
aDescriptor.Bounds = com::sun::star::awt::Rectangle(0,0,0,0);
aDescriptor.WindowAttributes = WindowAttribute::SHOW +
WindowAttribute::SIZEABLE;
Reference<XWindowPeer> xPeer = xToolkit->createWindow(aDescriptor);
// End Hack
hangs.
Any help would be appreciated.
