[Pharo-dev] ProportionalLayout indexForInserting: aMorph at: aPoint in: owner missing

[Stephan Eggermont]

Why does ProportionalLayout not have an implementation of
  indexForInserting: aMorph at: aPoint in: owner ?

I was trying to drag-and-drop columns and couldn't get
them to be reinserted att the right position.
