public class FontPreferencesImpl
extends ModifiableFontPreferences

Utility class which holds collection of font families and theirs sizes.

The basic idea is to allow end-user to configure not a single font but fonts list instead - every time particular font is unable to display particular char, next font is tried. This is an improvement over an old approach when it was possible to configure only a single font family. Fallback fonts were chosen randomly when that font family was unable to display particular char then.

Method Detail

setChangeListener

public void setChangeListener(java.lang.Runnable changeListener)

getChangeListener

public java.lang.Runnable getChangeListener()

clear

public void clear()

Specified by:

clear in class ModifiableFontPreferences

clearFonts

public void clearFonts()

Specified by:

clearFonts in class ModifiableFontPreferences

hasSize

public boolean hasSize(java.lang.String fontName)

Overrides:

hasSize in class FontPreferences

getLineSpacing

public float getLineSpacing()

Overrides:

getLineSpacing in class FontPreferences

setLineSpacing

public void setLineSpacing(float lineSpacing)

Specified by:

setLineSpacing in class ModifiableFontPreferences

getSize

public int getSize(java.lang.String fontFamily)

Overrides:

getSize in class FontPreferences

setSize

public void setSize(java.lang.String fontFamily,
                    int size)

getEffectiveFontFamilies

public java.util.List<java.lang.String> getEffectiveFontFamilies()

This method might return results different from getRealFontFamilies() when a font family unavailable at current environment has been registered at the current font preferences object.

Effective fonts will hold fallback values for such font families then (exposed by the current method), 'real fonts' will be available via getRealFontFamilies().

Overrides:

getEffectiveFontFamilies in class FontPreferences

Returns:

effective font families to use

getRealFontFamilies

public java.util.List<java.lang.String> getRealFontFamilies()

Overrides:

getRealFontFamilies in class FontPreferences

Returns:

'real' font families

getEffectiveFontFamilies()

register

public void register(java.lang.String fontFamily,
                     int size)

Specified by:

register in class ModifiableFontPreferences

getFontFamily

public java.lang.String getFontFamily()

Overrides:

getFontFamily in class FontPreferences

Returns:

first element of the registered font families (if any); FontPreferences.DEFAULT_FONT_NAME otherwise

addFontFamily

public void addFontFamily(java.lang.String fontFamily)

Specified by:
