Accessing the generic editor when subclassing GenericAudioProcessorEditor

[jc-lys]

Hi folks,

I’m subclassing the GenericAudioProcessorEditor to create a simple template for development, but I’ve added some labels to the editor - which I’d like to sit at the top of the window. All of the labels update correctly and work great (they’re based on a video by @eyalamir), it’s just the layout which I’m having this issue with.

I can’t seem to access the base class for the editor to move it down 50 or so pixels to allow the labels to fit.

PluginEditor.h

#ifndef PLUGINEDITOR_H_INCLUDED
#define PLUGINEDITOR_H_INCLUDED

#include <JuceHeader.h>
#include "PluginProcessor.h"

struct AtomicLabel:
    juce::Component,
    juce::Timer
{
    AtomicLabel(std::atomic<double>& valueToUse): value(valueToUse)
    {
        startTimerHz(60);
        addAndMakeVisible(label);
    }
    
    void resized() override
    {
        label.setBounds(getLocalBounds());
    }
    
    void timerCallback() override {
        label.setText(juce::String(value.load()), juce::dontSendNotification);
    }
    juce::Label label;
    std::atomic<double>& value;
};

class MyAudioProcessorEditor : public juce::GenericAudioProcessorEditor
{
public:
    MyAudioProcessorEditor (MyAudioProcessor&);
    ~MyAudioProcessorEditor() override;

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

private:
    MyAudioProcessor& processor;

    // host info
    AtomicLabel tempoLabel;
    AtomicLabel PPQLabel;
    AtomicLabel timeInSamplesLabel;

    JUCE_DECLARE_NON_COPYABLE_WITH_LEAK_DETECTOR (MyAudioProcessorEditor)
};


#endif  // PLUGINEDITOR_H_INCLUDED

PluginEditor.cpp

#include "PluginProcessor.h"
#include "PluginEditor.h"

MyAudioProcessorEditor::MyAudioProcessorEditor (MyAudioProcessor& p)
    : GenericAudioProcessorEditor (&p), processor (p), 
    tempoLabel(p.hostTempo), 
    PPQLabel(p.hostPPQ), 
    timeInSamplesLabel(p.hostTimeSamples)
{

    // host info
    // Note: this is drawn over the top of the GenericEditor
    addAndMakeVisible(tempoLabel);
    addAndMakeVisible(PPQLabel);
    addAndMakeVisible(timeInSamplesLabel);
    setSize(400,400);
}

MyAudioProcessorEditor::~MyAudioProcessorEditor()
{
}

void MyAudioProcessorEditor::paint (Graphics& g)
{
    // Note: this paint method is never called
    g.fillAll (getLookAndFeel().findColour(ResizableWindow::backgroundColourId));
    g.setColour (Colours::white);
    g.setFont (15.0f);
    g.drawFittedText ("Hello World", 0, 0, getWidth(), 30, juce::Justification::centred, 1);
    
}

void MyAudioProcessorEditor::resized()
{
    // this doesn't work.
    this->GenericAudioProcessorEditor::setTopLeftPosition(0,50);
   
    // host info
    tempoLabel.setBounds(105,10,50,50);
    PPQLabel.setBounds(160, 10, 65, 50);
    timeInSamplesLabel.setBounds(235, 10, 65, 50);
}

I would just like the ParametersPanel to move downward here under the three labels, i’m hoping it’s just an inheritance thing I’m missing?
