.SH DESCRIPTION
The QIconDragItem class is the internal data structure of a QIconDrag
.PP
This class is used internally in the QIconDrag to store the data of each item (in fact, a list of QIconDragItems is used by QIconDrag).
.PP
So, normally for each iconview item which is dragged, a QIconDragItem class (or a class derived from QIconDragItem) is created and stored in the QIconDrag object.
.PP
See QIconView::dragObject() for more information.
.PP
An example, how to implement this, is in the QtFileIconView example. (qt/examples/qfileiconview/qfileiconview.h and qt/examples/qfileiconview/qfileiconview.cpp).
.PP
Examples:
.(l
iconview/main.cpp
