Drag and Drop in a ListMorph
by Sean P. DeNigris 28 Nov '10

28 Nov '10

How (if at all) do I enable drag and drop in a SimpleHierarchicalListMorph? There is ListItemWrapper>>canBeDragged, which sounds good, but defaults to true, and still no dragging :( Specifically, I want to reorder the list items via drag and drop. Thanks. Sean n.b. I nabbled "ListMorph drag" and googled "Squeak ListMorph drag" with no joy -- View this message in context: http://forum.world.st/Drag-and-Drop-in-a-ListMorph-tp3058452p3058452.html Sent from the Squeak - Dev mailing list archive at Nabble.com.
