Class Fonts

java.lang.Object
org.pushingpixels.radiance.common.internal.font.Fonts
public final class Fonts extends Object
Provides static access to popular Windows fonts. The sizes of the font constants are specified in typographic points, approximately 1/72 of an inch.

TODO: Consider changing the visibility of the package private methods to public. As an alternative we may provide a FontPolicy that can emulate the font choice on Windows XP/2000 and Windows Vista for different software resolutions (96dpi/120dpi) and desktop font size settings (Normal/Large/Extra Large).

Since:
2.0

    • getWindowsControlFont

      public static Font getWindowsControlFont()
      Looks up and returns the Windows control font. Returns the Windows icon title font unless it is inappropriate for the Windows version, Java renderer, or locale.

      The icon title font scales with the resolution (96dpi, 101dpi, 120dpi, etc) and the desktop font size settings (normal, large, extra large). Older versions may return a poor font. Also, since Java 1.4 and Java 5 render the Windows Vista icon font Segoe UI poorly, we return the default GUI font in these environments.

      The last check is, if the icon font can display text in the default locale. Therefore we test if the locale's localized display name can be displayed by the icon font. For example, Tahoma can display "English", "Deutsch", but not the display name for "Chinese" in Chinese.

      Returns:
      the Windows control font
      Throws:
      UnsupportedOperationException - on non-Windows platforms

    • canDisplayLocalizedText

      public static Boolean canDisplayLocalizedText(Font font, Locale locale)
      Checks and answers whether the given font can display text that is localized for the specified locale. Returns null if we can't test it.

      First checks, if the locale's display language is available in localized form, for example "Deutsch" for the German locale. If so, we check if the given font can display the localized display language.

      Otherwise we check some known combinations of fonts and locales and return the associated results. For all other combinations, null is returned to indicate that we don't know whether the font can display text in the given locale.

      Parameters:
      font - the font to be tested
      locale - the locale to be used
      Returns:
      Boolean.TRUE if the font can display the locale's text, Boolean.FALSE if not, null if we don't know
