class LoadSound : public ThreadWithProgressWindow
{
public:
    LoadSound(EightAudioProcessor &processor) : ThreadWithProgressWindow("Loading...", true, false) {}

    void run(EightAudioProcessor &processor)
    {
      processor.clearSamplerSounds();
    }
};

void EightAudioProcessorEditor::loadFile()
{
    LoadSound loadSoundThread(processor);  

    if (loadSoundThread.runThread())
    {
        // thread finished normally..
    }
    else
    {
        // user pressed the cancel button..
    }
    
}

Found out that I can pass the editor to the Thread Constructor:

class LoadSound : public ThreadWithProgressWindow
{
public:
    EightAudioProcessorEditor& edi;
    LoadSound(EightAudioProcessorEditor& editor) : ThreadWithProgressWindow("Loading...", true, false)
    {
        editor.processor.clearSamplerSounds();
        edi = editor;
    }
...
void EightAudioProcessorEditor::loadFile()
{
    LoadSound loadSoundThread(*this);

    if (loadSoundThread.runThread())
    {
        // thread finished normally..
    }
    else
    {
        // user pressed the cancel button..
    }
    
}

But I cannot assign it to a public Variable inside the Thread Class.

Could fix it with:

class LoadSound : public ThreadWithProgressWindow
{
public:
    EightAudioProcessorEditor* editor;
    LoadSound(EightAudioProcessorEditor* editorInstance) : ThreadWithProgressWindow("Loading...", true, false)
    {
        editor = editorInstance;
    }

    void run()
    {
        editor->processor.clearSamplerSounds();
...
void EightAudioProcessorEditor::loadFile()
{
    LoadSound loadSoundThread(this);

    if (loadSoundThread.runThread())
    {
        // thread finished normally..
    }
    else
    {
        // user pressed the cancel button..
    }
    
}

I know that’s a terrible way. Even with this hacky “Solution” the UI doesn’t update.

Edit

The Calculation of the Percentage Value was not correct. Instead of:

setProgress((1 / (6 * 127)) * percentageIdx);

I need to use:

setProgress((1. / (6 * 127)) * percentageIdx);  // <<< Force to be `double`
