[Cuis-dev] LayoutMorph subclass instance #beColumn has not effect

[Mariano Montone]

I got it wrong. Seems that row layout layouts things horizontally, and 
column vertically.

As Hilaire mentioned, unless you want to define your own layout 
algorithm, the idea is to use the layout morphs, not subclass from them.

Layouts in a column (vertically):

LayoutMorph newColumn ::
         addMorph: (BoxedMorph new color: Color red; yourself);
         addMorph: (BoxedMorph new color: Color green; yourself);
         addMorph: (BoxedMorph new color: Color blue; yourself);
         openInWorld.

Layouts in a row (horizontally):
  LayoutMorph newRow ::
         addMorph: (BoxedMorph new color: Color red; yourself);
         addMorph: (BoxedMorph new color: Color green; yourself);
         addMorph: (BoxedMorph new color: Color blue; yourself);
         openInWorld.
