hello everyone,
I'm trying to use uno controls independently without OO runing.
but when I try to create the com.sun.star.awt.Toolkit service in my program,
it crashes.
I have tried to create other services (e.g. UnoButtonModel), and it seeems
ok.
I use OOo 2.4 on windows platform with Visual C++ for this testing, and here
is how I do:
first, I implement a uno component with XMain interface.
in its run method, I just try to get the service manager through the
component context that I have restored during the component instantiation.
virtual ::sal_Int32 SAL_CALL run(const Sequence< ::rtl::OUString >&
aArguments) SAL_THROW((RuntimeException))
{
if (m_xContext.is())
MessageBox(NULL, TEXT("1 OK!"), TEXT("Msg"), MB_OK);
Reference<lang::XMultiComponentFactory> xMultiFactory =
m_xContext.get()->getServiceManager();
if (xMultiFactory.is())
MessageBox(NULL, TEXT("2 OK!"), TEXT("Msg"), MB_OK);
Reference<XInterface> xInterface =
xMultiFactory.get()->createInstanceWithContext(L"com.sun.star.awt.Toolkit",
m_xContext);
if (xInterface.is())
MessageBox(NULL, TEXT("3 OK!"), TEXT("Msg"), MB_OK);
return 0;
}
then I register all uno dll components in [OFFICE_PROGRAM_PATH] with my
component into a new rdb file.(myservices.rdb)
finally I run uno -s MY_SERVICENAME -ro myservices.rdb to startup my uno
component.
when the component is runing, it shows the first two message boxes as
expected, and crashes without showing the last one.
but if I replace "com.sun.star.awt.Toolkit" with
"com.sun.star.awt.UnoButtonModel" or
"com.sun.star.awt.ContainerWindowProvider" instead, it runs correctly with
all message boxes displayed.
so why cant I create the Toolkit service in my component? does this serivce
depend on other services or things which I haven't prepared ready?
hope for your reply, and thanks very much!
Hi Rainman,
You have to make sure that VCL is properly initialized before you can
use UNO awt! UNO awt is a wrapper around VCL and cannot work correctly
if VCL has not been initialized. To initialize VCL you have to call
InitVCL(...). You can find how to call InitVCL in the desktop project,
e.g. look within desktop/source/pkgchk/unopkg/unopkg_misc.cxx at the
function getUNO(...). There is also a function called DeInitVCL().
Regards,
Carsten
