Detailed Description

Quality recording bar.

In the Signal-Analyzer panel the tuner application shows a vertical progress bar which indicates the quality of the recorded key. The quality is a number between 0 and 1 which is computed heuristically by the FFTAnalyzer and can be interpreted as a measure how nicely the observed partials match with the usual inharmonicity formula.

void RecordingQualityBar::handleMessage ( MessagePtr m )

finaloverrideprivatevirtual

Message handling.

Parameters

m	: The message.

Implements MessageListener.

Definition at line 109 of file recordingqualitybar.cpp.

Here is the call graph for this function:

QSize RecordingQualityBar::minimumSizeHint ( ) const

finaloverridevirtual

Hint for the minimal widget size.

Returns: QSize hint.

The minimum size is set by the minimum space the text requires.

Definition at line 60 of file recordingqualitybar.cpp.

void RecordingQualityBar::paintEvent ( QPaintEvent * event )

finaloverrideprivate

Reimplemented paint function that will draw the vertical text.

Parameters

event : The QPaintEvent.

Definition at line 142 of file recordingqualitybar.cpp.

QSize RecordingQualityBar::sizeHint ( ) const

finaloverridevirtual

Hint for the optimal widget size.

Returns: QSize hint.

The optimal size is the minimuimSizeHint() with a small padding.

Definition at line 66 of file recordingqualitybar.cpp.

void RecordingQualityBar::updateValue ( float v )

private

Function to update the current value.

RecordingQualityBar::updateValue.

Parameters

v	: The new value to display

Update the quality measure bar. According to the argument v in the range from 0 to 1 the bar is filled from bottom to top. The color changes continuously with the value from red over orange to green.

Parameters

v	: Quality between 0 and 1
