This method is only allowed to be called by a sub-frame according to
::com::sun::star::frame::XFrame::activate() or ::com::sun::star::frame::XFramesSupplier::setActiveFrame() .
After this call ::com::sun::star::frame::XFramesSupplier::getActiveFrame() will return the
frame specified by Frame .
In general this method first calls the method ::com::sun::star::frame::XFramesSupplier::setActiveFrame()
at the creator frame with this as the current argument. Then it broadcasts
the ::com::sun::star::frame::FrameActionEvent FrameAction::FRAME_ACTIVATED .
Note: Given parameter Frame must already exist inside the container
(e.g., inserted by using ::com::sun::star::frame::XFrames::append() )
