NOT AT ALL ;-)

for :
	def outlineView_numberOfChildrenOfItem(aTree, bookmark)

i return a fixnum

for :
	def outlineView_isItemExpandable(aTree, bookmark)
i return a boolean (ruby) like that :
       return bookmark.has_elements?()
or :
     return false

for :
	def outlineView_child_ofItem(aTree, index, bookmark)
i return a REXML::Element :
       return children[index]

for :
=09
	def outlineView_objectValueForTableColumn_byItem(aTree, =
tableColumn, =20
bookmark)
i return ruby string :
for example :
         return bookmark.attributes["label"] if =20
(tableColumnIdentifier =3D=3D "Label")
         return bookmark.attributes["href"] if (tableColumnIdentifier =20=

=3D=3D "Url")

and finally for :
	def outlineView_shouldEditTableColumn_item(aTree, tableColumn, =20=

bookmark)
i return a ruby boolean always as :
		return false


thaks for your help !
