Getting the Font Faces for a Font Family
To create a Font object to draw text, it is necessary to specify
the font face name. This example demonstrates how to retrieve all the
font face names from a font family name. Unfortunately, the method is
somewhat inefficient since it involves creating one-point size
Font objects for every available font in the system. The example
caches all the information by creating a hash table that maps a font
family name to an array of font face names.
See also Listing All Available Font Families. Note: J2SE 1.4
only support True Type fonts.
Map fontFaceNames = new HashMap();
// Get all available font faces names
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
Font[] fonts = ge.getAllFonts();
// Process each font
for (int i=0; i<fonts.length; i++) {
// Get font's family and face
String familyName = fonts[i].getFamily();
String faceName = fonts[i].getName();
// Add font to table
java.util.List list = (java.util.List)fontFaceNames.get(familyName);
if (list == null) {
list = new ArrayList();
fontFaceNames.put(familyName, list);
}
list.add(faceName);
}
// Replace the face name lists with string arrays,
// which are more compact and convenient to use
for (Iterator it=fontFaceNames.keySet().iterator(); it.hasNext(); ) {
String familyName = (String)it.next();
java.util.List list = (java.util.List)fontFaceNames.get(familyName);
fontFaceNames.put(familyName, list.toArray(new String[list.size()]));
}
// Use the table
String[] faces = (String[])fontFaceNames.get("Verdana");
