[Cuis-dev] adding a morph to start of LayoutMorph

[Hilaire Fernandes]

Use the source, Mark!

You will discover that addMorph: and addMorphFront: are identical in the 
context of LayoutMorph. Indeed, there can't be a notion of Z-ordering in 
a LayoutMorph.


LayoutMorph>>addMorph:  aMorph
	"Add a submorph, at the bottom or right, with a default LayoutSpec if 
none was provided."

	aMorph  isPlacedMorph  ifFalse:  [self  error:  'Only PlacedMorphs can be used in Layouts'  ].
	aMorph  layoutSpec.
	super  addMorphFront:  aMorph



By the way Juan, addMorph: and addMorphFront are perfect twins. Any 
reason to not let addMorph: send the message addMorphFront: to self?
