Attribute types

An attribute is of one of the following type:

• int: An integer attribute has a domain: -999999..999999.
• boolean: A boolean attribute is either true or false.
• char: A character attribute can take any character as its value. If the system cannot determine a value for a character attribute, then it assigns space ' ' to the attribute.
• String: The default value is ``''.
• Color: For this attribute, the following constants can be used:

         black, blue, cyan, darkGray, gray, lightGray, magenta, 
         orange, pink, red, white, yellow
  

  The default color is black.
• Font:

         class Font {
               dj String name;
               dj int size > 0;
               dj int style in 0..3;
         }
  

  Font names have the following domain: ``Dialog'', ``Courier'', ''TimesRoman'', ''Helvetica'', ''ZapfDingbats'', ''DialogInput''. The default value for font names is the default font name used by Java for applets. For font style attributes, the following constants can be used.

         PLAIN = 0
         BOLD = 1
         ITALIC =2
         BOLD+ITALIC =3
  

  Assigning a value outside of the range 0..3 to a font style will cause an error.

• Dimension:

         class Dimension {
               dj int width;
               dj int height;
         }
  

• Point:

         class Point {
               dj int x;
               dj int y;
         }
