Hi He Feng Su,
Please try to use "com.sun.star.awt.AsyncCallback" service to get a
callback from the office main thread. You will need an own object
implementing com::sun::star::awt::XCallback interface. This object will
be provided to the com::sun::star::awt::XRequestCallback::addCallback()
call.
Just to explain the mechanics for better understanding. When java
application calls an UNO API method through a bridge, a new thread is
created on Office side and the method is executed in this thread.
When the XRequestCallback.addCallback() is called it sends a
notification with arguments to the main office thread and returns. After
a while the main thread calls XCallback::notify(), and if this method
does a call to the office back, the call is handled in the office main
thread.
Hope that helps.
Best regards,
Mikhail.
