I implemented the above code with c++ . However, it did not work. Anything
wrong with the following code:
m_xCC is a given Reference<XComponentContext>
Reference<XEventBroadcaster>
xBrd(m_xCC->getServiceManager()->createInstanceWithContext(OUString(RTL_CONSTASCII_USTRINGPARAM("com.sun.star.frame.GlobalEventbroadcaster")),
m_xCC), UNO_QUERY); //xBrd is still empty, not sure why?
if (xBrd.is())
{
Reference< XEventListener > xDocListener(
static_cast<XEventListener*>(new CalcListener()),
UNO_QUERY);
xBrd->addEventListener(xDocListener);
}
Thanks,
Wendi
