From b13aa15e1007a1b5ed61049bbd9ef8f95b6d12a5 Mon Sep 17 00:00:00 2001 From: David Faure Date: Fri, 21 Nov 2014 10:46:22 +0100 Subject: QAbstractItemView: call canDropMimeData, as one would expect. The virtual method was added for 5.0 but never called. The old code (only checking mimetypes) is now the default implementation for canDropMimeData. Model subclasses can now refine this by having index-specific logic instead, or in order to inspect the dropped data (e.g. to accept files and refuse directories, which are all text/uri-list). [ChangeLog][QtWidgets][QAbstractItemView] now calls canDropMimeData in order to decide whether or not to accept the drop.
