MessageForwarderThread Class Reference

Inheritance diagram for MessageForwarderThread:

Signals
void	sigDeliverMessage (QtMsgType type, const QString &message)

Public Member Functions
void	pushExitFlag ()
void	pushMessage (QtMsgType type, const QString &message)
void	run () override

Private Attributes
bool	m_exitFlag {false}
QQueue< std::pair< QtMsgType, QString > >	m_messages
QMutex	m_mutex
QWaitCondition	m_waitCondition

Detailed Description

A background thread that receives all the debug messages from the main thread and resends them forward using qt-signals. We cannot resend the message in the same thread, because the a qDebug() message can come form the qt-signaling code, which can cause deadlocks.
