DESCRIPTION
The QIconDrag class is the drag object which is used for
moving items in the iconview
The QIconDrag is the drag object which is used for moving
items in the iconview. The QIconDrag stores exact
informations about the positions of the items, which are
dragged, so that each iconview is able to draw drag shapes
in correct positions. Also the data of each dragged item
is stored here.
If you want to use extended DnD functionality of the
QIconView, normally it's enough to just create a QIconDrag
object in QIconView::dragObject(). Then create for each
item which should be dragged a QIconDragItem and set the
data it represents with QIconDragItem::setData() and add
this item to the drag object using append().
If you want to offer the data in other mime-types too,
derive a class from this and implement the needed encoding
and decoding here.
An example, how to implement this, is in the
QtFileIconView example
(qt/examples/qfileiconview/qfileiconview.h and
qt/examples/qfileiconview/qfileiconview.cpp).
