Dear all,
I have two custom models associated with views and I would like to drag
from model A and drop into model B.
Model B has overloaded supportedDropActions and returns Qt::LinkAction
Model A has overloaded supportedDragActions and returns Qt::MoveAction |
Qt::LinkAction
This does not work as the cursor turns to a forbidden sign when dragging
over B.
If model A supportedDragActions returns Qt::LinkAction only, then this
works.
If I look to the source code of QAbstractItemViewPrivate, i find in
canDecode(QDropEvent * e):
if (mime->hasFormat(modelTypes.at(i))
&& (e->dropAction() & model->supportedDropActions()))
return true;
Which explains the issue, the event handler does not check the event's
possible drop actions and does not call setDropAction if the proposed
action is not supported.
Is this a bug or a feature?
Thanks
