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.

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.

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.
