I’m creating a parameterLayout in my configurationManager class. However this member function of my class doesn’t work:
AudioProcessorValueTreeState::ParameterLayout ConfigurationManager::createParameterLayout()
{
return m_pLayout;
}
The compiler tells me that it is a deleted function. Why is that? The brute-force method of course would be to make my parameterLayout public…
ParameterLayout cannot be copied because it contains a std::vector<std::unique_ptr> and std::unique_ptr cannot be copied.
They’ve disabled the copy constructor for ParameterLayout to signify that they shouldn’t be copied. You could try returning a reference or const reference to the layout in your method. (Or move it to the return value with std::move, but that would make the ConfigurationManager class member m_pLayout invalid for later use…)
ok, that makes sense! I wanted to generate my parameterLayout before calling createParameterLayout(). I will try the reference, thanks!

I found this post from @t0m most helpful:
Here’s one way of doing it:
AudioProcessorValueTreeState::ParameterLayout createParameterLayout()
{
std::vector<std::unique_ptr<AudioParameterInt>> params;
for (int i = 1; i < 9; ++i)
params.push_back (std::make_unique<AudioParameterInt> (String (i), String (i), 0, i, 0));
return { params.begin(), params.end() };
}
YourAudioProcessor()
: parameters (*this, &undoManager, "PARAMS", createParameterLayout())
I use it that way in my open source project:
std::move (gainParameter),
std::move (actvParameter));
params.push_back (std::move (group));
}
return { params.begin(), params.end() };
}

FrequalizerAudioProcessor::FrequalizerAudioProcessor() :
#ifndef JucePlugin_PreferredChannelConfigurations
AudioProcessor (BusesProperties()
.withInput ("Input", juce::AudioChannelSet::stereo(), true)
.withOutput ("Output", juce::AudioChannelSet::stereo(), true)
),
#endif
state (*this, &undo, "PARAMS", createParameterLayout())
{
frequencies.resize (300);
for (size_t i=0; i < frequencies.size(); ++i) {
Sweet, got it all sorted out now, thanks!
