[JUCE API] Customizing The GUI(2)

After setting the GUI's color, I changed the text's font and slider image.

namespace BinaryData
{
    extern const char*   LatoMedium_ttf;
    const int            LatoMedium_ttfSize = 663564;
}

If we imported the .ttf file and we can check at BinaryData.header file in JUCE Library Code group.

class MyLookAndFeel  : public juce::LookAndFeel_V4
{
private:
    juce::FontOptions mFontOption;
}
mFontOption(juce::Typeface::createSystemTypefaceFor(BinaryData::LatoMedium_ttf,
                                                    BinaryData::LatoMedium_ttfSize))

I made the juce::FontOptions object and received the font's data as argument.

class JUCE_API  LookAndFeel  :  public Label::LookAndFeelMethods

struct JUCE_API  LookAndFeelMethods
    {
        virtual ~LookAndFeelMethods() = default;

        virtual void drawLabel (Graphics&, Label&) = 0;
        virtual Font getLabelFont (Label&) = 0;
        virtual BorderSize<int> getLabelBorderSize (Label&) = 0;
    };

The LookAndFeel class is derived from Labe::LookAndFeelMethods, which has pure virtual functions.

• drawLabel() :
  Defines how the Label is drawn.
• getLabelFont() :
  Determines the font used for the Label.
• getLabelBorderSize() :
  Specifies the border size around the Label.

getLabelFont() is for handling the label's font.

juce::Font MyLookAndFeel::getLabelFont (juce::Label& inLabel)
{
    // Default
    return  juce::LookAndFeel_V4::getLabelFont(inLabel);
}

If we want to use the default font, just get the juce::LookAndFeel_V4's font.

juce::Font MyLookAndFeel::getLabelFont (juce::Label& inLabel)
{
    // Default
    //return  juce::LookAndFeel_V4::getLabelFont(inLabel);
    return mFontOption.withMetricsKind(juce::TypefaceMetricsKind::legacy).withHeight(MySize::Font::Height);
    
}

As I brought the juce::FontOptions's object, all of the label's font has changed.

void MyLoodAndFeel::drawRotarySlider (juce::Graphics& g,
                                       int x, int y, int width, int height,
                                       float sliderPosProportional,
                                       float rotaryStartAngle,
                                       float rotaryEndAngle,
                                       juce::Slider& s)
{
    
}

There is also pure virtual function drawRotarySlider() in Slider class, but there isn't return type. So if we don't define the function, that gonna show up without image.
