mixin

graph-pasteboard-mixin : (class? . -> . class?)

  argument extends/implements: pasteboard%
  result implements: graph-pasteboard<%>

constructor

(new graph-pasteboard-mixin 
    [[edge-labels? edge-labels?] 
    [edge-label-font edge-label-font]] 
    [cache-arrow-drawing? cache-arrow-drawing?] 
    ...superclass-args...) 
 → (is-a?/c graph-pasteboard-mixin)
  edge-labels? : boolean? = #t
  edge-label-font : (or/c #f (is-a?/c font%)) = #f
  cache-arrow-drawing? : any
If edge-labels? is #f, no edge labels are drawn. Otherwise, they are.

If edge-label-font is supplied, it is used when drawing the labels on the edges. Otherwise, the font is not set before drawing the labels, defaulting to the dc<%> object’s font.

If cache-arrow-drawing? is #f, then the arrows in the snip are not cached in a bitmap (to speed up drawing when the mouse moves around). Otherwise, they are.

This mixin overrides many methods to draw lines between graph-snip<%> that it contains.
