Embedded TTF to use

Audio Plugins
1

Maybe it's just me, but after spending a day searching this forum and reading everything here couldn't find exact answers for these question, so thought to ask here, maybe somebody can clarify them:

I would like to use my own embedded TTF in my plugin so I made the next few steps:

 

MyLookAndFeel::MyLookAndFeel() :
    m_fontRegular(Typeface::createSystemTypefaceFor(BinaryData::FontRegular_ttf, BinaryData::FontRegular_ttfSize)),
    m_fontRegularItalic(Typeface::createSystemTypefaceFor(BinaryData::FontRegularIt_ttf, BinaryData::FontRegularIt_ttfSize)),
    m_fontBold(Typeface::createSystemTypefaceFor(BinaryData::FontBold_ttf, BinaryData::FontBold_ttfSize)),
    m_fontBoldItalic(Typeface::createSystemTypefaceFor(BinaryData::FontBoldIt_ttf, BinaryData::FontBoldIt_ttfSize)) {}

Typeface::Ptr MyLookAndFeel::getTypefaceForFont(const juce::Font & font) {
    if (font.getTypefaceName() == "My Font Name") {
        if (font.isBold() && font.isItalic()) return m_fontBoldItalic;
        if (font.isBold()) return m_fontBold;
        if (font.isItalic()) return m_fontRegularItalic;
        return m_fontRegular;
    }
    return LookAndFeel::getTypefaceForFont(font);
}

And I add the LookAndFeel object to my editor this way:

MyplayerAudioProcessorEditor::MyplayerAudioProcessorEditor (MyplayerAudioProcessor& p) {
   setLookAndFeel(&m_lookAndFeel);
   Desktop::getInstance().setDefaultLookAndFeel(&m_lookAndFeel);
   ...
}

Now the questions:

1,  if I don't use this line: "Desktop::getInstance().setDefaultLookAndFeel(&m_lookAndFeel);", my "getTypefaceForFont()" never will be called. Why?

2, If I want this to work, then I should add that line and replace "My Font Name" with "<Sans-Serif>" in my "getTypeFaceForFont()" function.  It seems a bit hacky, but would be interested why this works and if this is the way it should work? I found this solution in this thread and it is working now: http://www.juce.com/forum/topic/embedded-fonts-os-x-truetype

3, In my own Components if I call this method: "g.getCurrentFont().findAllTypefaceNames()" my typefaces aren't listed. Is it normal as this function only lists the system fonts and doesn't list the plugin's own registered fonts?

 

Thanks in advance,

Kevin
