From 35f964ac3d88831c857a850bbdc58fcbfdbaf13c Mon Sep 17 00:00:00 2001 From: Martin Jones Date: Mon, 13 Dec 2010 13:49:52 +1000 Subject: A QAIM model resulted in items moving to incorrect locations QAbstractItemModel moves items to the gaps between items. QML views assume items are moved to the destination index. This means we need to adjust the destination when moving forward to a gap.
