    <p>I quickly tried it out, but could quite make it work using an object. There I had to use draw(ball) instead of draw ball, as you wanted:</p> <p><pre><code> Welcome to Scala version 2.8.0.RC2 (Java HotSpot(TM) 64-Bit Server VM, Java 1.6.0_20).</p> <p>scala> trait Drawable{def doSomething} defined trait Drawable</p> <p>scala> object Draw {<br> def draw(d:Drawable) = d.doSomething } defined module Draw</p> <p>scala> val ball = new Drawable{def doSomething = println("doing ball")} ball: java.lang.Object with Drawable = $anon$1@3a4ba4d6</p> <p>scala> import Draw._ import Draw._</p> <p>scala> draw ball :11: error: missing arguments for method draw in object Draw; follow this method with `_' if you want to treat it as a partially applied function draw ball ^</p> <p>scala> draw(ball) doing ball </pre></code></p> <p>However by defining Draw as a class, it did work:</p> <p><pre><code> scala> trait Drawable{def doSomething: Unit} defined trait Drawable</p> <p>scala> class Draw {<br> def draw(d:Drawable) = d.doSomething } defined class Draw</p> <p>scala> </p> <p>scala> val ball = new Drawable{def doSomething = println("doing ball")} ball: java.lang.Object with Drawable = $anon$1@36a06816</p> <p>scala> val d = new Draw d: Draw = Draw@7194f467</p> <p>scala> d draw ball doing ball </pre></code></p> <p>I'm not completely sure why this doesn't work the same way with an object, might be a bug or perhaps that's specified behaviour. However I didn't have the time to look it up at the moment.</p>

    1. COThe problem with your first version is that Scala's "operator notation" needs an explicit receiver, that's why the class example works.

    2. COI think draw(ball) could be acceptable syntax. I would have something like draw(ball) at (x,y,z) on someOpenGlPanel. It is just a test of doing a small DSL anyway :) Thanks for your answer. Btw: maybe one could accept some filler symbol like Draw -> ball or whatever...back to thinking :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
