The attached patch works except that the block jumps off the cursor when starting the drag. Ideas? 85.txt

stephanemagnenat commented 6 years ago

Some ideas:

Could it be that the positioning is done relative to the parent, and that by changing parent the block jumps?
Could it be something linked to Drag.hotSpot?
Should one change anchoring as well as in http://doc.qt.io/qt-5/qtquick-draganddrop-example.html?

Positioning is done by QML's RowLayout, and setting it in a PropertyChanges changes nothing
Drag.hotSpot is not set, and setting it changes nothing
Anchors are not set, and setting them in an AnchorChanges changes nothing
