Sgraphics is much simpler, but hopefully simpler to use as well. Fresco is no longer supported by X-consortium or Fujitsu. So, please don't e-mail any of the people referenced in the tutorial with questions. Glyph Basics First lets start with the basics. Below is a class diagram of the basic geometry management and event handling classes.
Lets go through each class one by one.
Glyphs Glyph, MonoGlyph, and PolyGlyph The glyph is the basic graphical unit of Sgraphics. Just about every class inherits from the Glyph interface, everything from lines to buttons, and from event handlers to layout classes. Glyphs are used like small building blocks that can be connected an various ways. GlyphImpl implements basic behavior for all glyphs. MonoGlyph is based on a Decorator pattern.
