I have updated the API's to support x/y 'spread' and points, as suggested by Frank.
The general rule is '-*' a the end of a function indicates that the function takes a parameter spread of x/y or x/y/w/h. I chose the '-*' to indicate a spread as emacs will expand "d-l" to draw-line, and "d-l-" to draw-line-* . I dislike having to shift-8 to get a *. For example: draw-line X0 Y0 X1 Y1 draw-line-* POINT draw-rectangle RECTANGLE draw-rectangle-* X Y W H I have also added generic methods that act on points, rectangles and surfaces: (defgeneric point-* (obj)) (defgeneric set-point (obj point)) (defgeneric set-point-* (obj &key x y)) (defgeneric position-* (obj)) (defgeneric set-position (dst src)) (defgeneric set-position-* (obj &key x y)) (defgeneric rectangle-* (rectangle)) (defgeneric set-rectangle (rectangle position)) (defgeneric set-rectangle-* (rectangle &key x y w h)) (defgeneric set-surface (surface position)) (defgeneric set-surface-* (surface &key x y)) "point-*", "position-*" and "rectangle-*" return separate x/y or x/y/w/h parameters for the object using VALUES. I think the API is becoming more consistent, which is good. There are a couple of inconsistencies that remain, for example some functions take keyword parameters and others do not: (RECTANGLE :x x :y y :w w :h h) , and (set-rectangle-* x y w h) And some API's take ":FREE t" and others ":FREE-P t" to free a surface. - Luke _______________________________________________ application-builder mailing list application-builder@lispniks.com http://www.lispniks.com/mailman/listinfo/application-builder
