From 55cd05c857bbc0489cbae0edd74ef4283416bff1 Mon Sep 17 00:00:00 2001 From: Shawn Rutledge Date: Tue, 11 Jun 2024 18:36:54 -0700 Subject: Doc: Override DragHandler.accepted* and margin DragHandler docs have been showing TapHandler code snippets, because both DragHandler and TapHandler inherit properties from PointerDeviceHandler, which is abstract and uses TapHandler code snippets in some of its property documentation. Override documentation for acceptedDevices, acceptedModifiers, acceptedPointerTypes and margin by adding to the DragHandler class, and add testable snippets for a couple of them. draggableGridView is adapted from examples/quick/draganddrop/views/gridview.qml.
