AudioThumbnail - Undefined?

General JUCE discussion
1

Hi all,

I’m trying to implement the AudioThumbnail class in a new component, but I’m having some trouble - for both AudioThumbnail and AudioThumbnailCache, VS shows the error “identifier “AudioThumbnail” is not defined”.

It’s a totally standard JUCE component generated with the Projucer, and JuceHeader is included. Everything else like AudioFormatManager and AudioTransportSource shows up as expected. After some looking through docs and tutorials I am still not sure what is going wrong.

Am I missing a dependency or something completely obvious here? Header code below:

#ifndef WAVEFORMCOMPONENT_H_INCLUDED
#define WAVEFORMCOMPONENT_H_INCLUDED

#include "../JuceLibraryCode/JuceHeader.h"

//==============================================================================
/*
*/
class WaveformComponent    : public Component, private ChangeListener
{
public:
    WaveformComponent();
    ~WaveformComponent();

    void paint (Graphics&) override;
    void resized() override;

    AudioFormatManager formatManager;
    ScopedPointer<AudioFormatReaderSource> readerSource;
    AudioTransportSource transportSource;
    AudioThumbnailCache thumbnailCache;
    AudioThumbnail thumbnail;
private:
    JUCE_DECLARE_NON_COPYABLE_WITH_LEAK_DETECTOR (WaveformComponent)
};

#endif  // WAVEFORMCOMPONENT_H_INCLUDED

Thanks!

You need the juce_audio_utils module

That was it! Thought I had all modules added already, but I hadn’t.

Thanks!
