Detailed Description

Drawer for the tuning indicator.

This class draws the content of the tuning indicator in the tuning mode. It is completely driven by messages. There are two operation modes depending on the settings: (a) the spectral mode, where a zoomed part of the spectrum is displayed which has to be brought to the center, and (b) the stroboscopic mode, where a stroboscopic interference pattern is shown in rainbow colors.

void TuningIndicatorDrawer::clear ( )

Clear the shared pointer to the FFT.

Reimplemented from DrawerBase.

Here is the call graph for this function:

void TuningIndicatorDrawer::draw ( )

finaloverrideprotectedvirtual

Main drawing function.

This is the main drawing function for the tuning indicator. In the stroboscopic mode the complex phases of the partials are simply fowarded to the function drawStroboscope of the GraphicsViewAdapter. This means that the drawing of the stroboscope is done by the implementation for the sake of fast response. In the spectral mode the drawing is carried out by the present function.

Implements DrawerBase.

void TuningIndicatorDrawer::handleMessage ( MessagePtr  m )

Message listener.

The message listener handles the incoming messages and takes the corresponding action.

Parameters

m	: Pointer to the incoming message

Implements MessageListener.
