Also, both vertical >and horizontal layouts would be supported. I wrote a class that displays a directed acyclic graph layout (which works fine for trees, too) using Glyphs. It used to be a MonoScene, but I converted it to a Page subclass. It seems to work pretty well now, but scrolling is slow -- I implemented a generic scrollable, Viewport-like class for Glyphs that scrolls by changing the allocation of the interior glyph, and that's much slowed than scrolling with Interactors and Viewports. InterViews people: Are there plans for a Glyph-based "Viewport" object that works faster than mine? ;-) Bob: I'll show you my code if you want to see it. -greg +----------------------------------------------------+ Greg Brail Internet: gjb@cs.brown.edu BITNET: gjb@browncs.bitnet UUCP: ..uunet!brunix!gjb Home: (401)273-1172
