quirement that the first argument be Font.TRUETYPE_FONT , only TrueType fonts are suppor-
ted at present. The Font class documentation, ever the optimist, states that this field is to al-

ability of free PostScript font renderers, such as the one in the X Window System XFree86, it
should be possible to add PostScript font support in the future. Example 12-4 is a listing of a
small standalone application that creates the window shown in Figure 12-5 .
