Detailed Description

An AudioDisplayComponent displays the content of audio data and has some areas that can be dragged and send a change message on Mouse up.

You can create subclasses of this component and populate it with some SampleArea objects (you can nest them if desired)

Constructor & Destructor Documentation

virtual ~AudioDisplayComponent ( )

inlinevirtual

Removes all listeners.

void addAreaListener ( Listener * l )

inline

Adds an AreaListener that will be informed whenever a Area was dragged.

void drawPlaybackBar ( Graphics & g )

draws a vertical ruler to display the current playing position.

void setCurrentArea ( SampleArea * area )

inline

Sets the current Area .

void setPlaybackPosition ( double normalizedPlaybackPosition )

inline

Sets the playback position for (0 ...

PlayArea::numSamples)

If you need this functionality, use a timer callback to call this periodically.

virtual void updateRanges ( SampleArea * areaToSkip = nullptr )

pure virtual

Overwrite this method and update the ranges of all SampleAreas of the AudioDisplayComponent.

Remember to call refreshSampleAreaBounds() at the end of your method.<w
