<P>
The <code>Font</code> class represents fonts and font metrics. <code>Fonts</code> cannot be created by applications. Instead, applications query for fonts based on font attributes and the system will attempt to provide a font that matches the requested attributes as closely as possible. <p> A <code>Font's</code> attributes are style, size, and face. Values for attributes must be specified in terms of symbolic constants. Values for the style attribute may be combined using the bit-wise <code>OR</code> operator, whereas values for the other attributes may not be combined. For example, the value </p> <p> <code> STYLE_BOLD | STYLE_ITALIC </code> </p> <p> may be used to specify a bold-italic font; however </p> <p> <code> SIZE_LARGE | SIZE_SMALL </code> </p> <p> is illegal. </p> <p> The values of these constants are arranged so that zero is valid for each attribute and can be used to specify a reasonable default font for the system. For clarity of programming, the following symbolic constants are provided and are defined to have values of zero: </p> <p> <ul> <li> <code> STYLE_PLAIN </code> </li> <li> <code> SIZE_MEDIUM </code> </li> <li> <code> FACE_SYSTEM </code> </li> </ul> </p> <p> Values for other attributes are arranged to have disjoint bit patterns in order to raise errors if they are inadvertently misused (for example, using <code>FACE_PROPORTIONAL</code> where a style is required). However, the values for the different attributes are not intended to be combined with each other. </p>
