bool Common::OSDMessageQueue::pollEvent ( Common::Event & event ) [override, virtual]

Common::EventSource interface.

The OSDMessageQueue registers itself as an event source even if it does not actually produce events as a mean to be polled periodically by the GUI or engine code.

The periodical polling is used to update the OSD messages.

Implements Common::EventSource.
