customEvent()

void MythSystemEventHandler::customEvent ( QEvent *  e )

overrideprivate

Custom Event handler for receiving and processing System Events.

See also

MythSystemEventHandler::SubstituteMatches(const QStringList &tokens, QString &command) MythSystemEventHandler::EventNameToSetting(const QString &name)

This function listens for SYSTEM_EVENT messages and fires off any necessary event handler commands. In addition to SYSTEM_EVENT messages, this code also forwards GLOBAL_SYSTEM_EVENT which may have been sent by the local system via code that does not have access to the master backend connection to send events on its own. One example is the code that sends KEY_xx system events.

Parameters

e	Pointer to QEvent containing event to handle
