McCLIM changes: backends, graphs, better examples, new demo

Thursday, August 18, 2005

There were several McCLIM CVS commits within the past couple of months or so:

• Andreas Fuchs added a Bistream Vera font detection routine to the Freetype backend, and fixed some pages of the web site.
• Christophe Rhodes fixed the sense of rotation in the PostScript backend, and a presentations typo. He also fixed the way the bounding rectangle for characters that do not lie entirely within the ascents/descents are managed by the Freetype and PostScript backends.
• Tim Moore implemented a better generic output record hash.
• Robert Goldman added a layout method for DAGs to format-graph-from-roots, and exported format-graph-from-root.
• Robert Strandh improved some examples in the manual, started an incremental redisplay cleanup, and applied a patch related to partial commands in accepting-values by Max-Gerd Retzlaff. He also added the new demo (includes link to a screen shot) Examples/town-example.lisp also contributed by Max.

  The new demo displays information on major German cities via an interactive map and a command prompt. It demonstrates several CLIM concepts, which Max lists:

  custom view classes, different present presentation methods for different views, completion for accept presentation methods, accepting-values dialogues, presentation to command translators, partial commands in menus, automatically generated menus

  To run the demo, compile/load the file town-demo.lisp and evaluate (town-example:run). Click on a city to get info.
