Virtual worker function called periodically from the timer.

Reimplemented in Tuner, and AudioDeviceGuard.

Definition at line 89 of file threadbase.h.

Here is the call graph for this function:

void MidiHandler::receiveMidiEvent ( const QMidiMessage & event )

slot

Definition at line 56 of file midihandler.cpp.

Here is the call graph for this function:

void ThreadBase::resume ( )

virtualinherited

Resume from the suspend mode.

Restart the timer and clear the mSuspended flag

Reimplemented in MidiPlayer.

Definition at line 99 of file threadbase.cpp.

void ThreadBase::setPriority ( const QThread::Priority p )

protectedinherited

Set thread priority.

Definition at line 109 of file threadbase.cpp.

Here is the call graph for this function:

void MidiHandler::setQmlTemperamentIndex ( QVariant index )

signal

void ThreadBase::setThreadName ( const QString name )

protectedinherited

Set thread name (Linux only)

Here is the call graph for this function:

void ThreadBase::setTimerInterval	(	const int	msec,
		const int	firstMsec = `0`
	)

protectedinherited

Set timer interval for the periodically called worker.

Definition at line 117 of file threadbase.cpp.

Here is the call graph for this function:

void ThreadBase::setVerbosity ( int verbosity )

inherited

Set verbosity level of messages.

Here is the call graph for this function:

void MidiHandler::signalSoftPedal ( bool pressed )

signal

void MidiHandler::signalSostenutoPedal ( bool pressed )

signal

void MidiHandler::signalSustainPedal ( bool pressed )

signal

bool ThreadBase::start ( )

virtualinherited

Start the thread.

Starts the thread. If the thread is suspended it will resume. If the thread is already started the function does nothing.

Returns: True on succes

Reimplemented in Tuner, and AudioOutput.

Definition at line 64 of file threadbase.cpp.

Here is the call graph for this function:

bool ThreadBase::stop ( )

virtualinherited

Stop the thread.

Send a termination request to the execution loop. Wait for the thread to terminate. The active components of the thread should call isInterruptionRequested() and quit immediately if this function is true.

Returns: If the thread terminates regularly return true. If the thread does not terminate after a timeout of 2 secs return false.

Reimplemented in MidiPlayer, AudioOutput, and Instrument.

Definition at line 152 of file threadbase.cpp.

Here is the call graph for this function:

void ThreadBase::suspend ( )

virtualinherited

Mark the thread as suspended.

Calling this function tells the thread that it has to wait in some sort of standby. Note that the thread itself is not terminated and that the event loop is still active. Calling this function stops the timer so that the periodicallyCalledWorker() is not active any more. In addition the mSuspended flag is set.

Reimplemented in MidiPlayer, and SoundGenerator.
