Inheritance diagram for KMultipleDrag:

Detailed Description
This class makes it easy for applications to provide a drag object (for drag-n-drop or for clipboard) that has several representations of the same data, under different formats.Instead of creating a specific class for each case (as would otherwise be necessary), you can simply create independent drag objects (e.g. a QImageDrag object and a KURLDrag object), and bundle them together using KMultipleDrag.
Sample code for this:
KMultipleDrag *drag = new KMultipleDrag( parentWidget ); drag->addDragObject( new QImageDrag( someQImage, 0 ) ); drag->addDragObject( new KURLDrag( someKURL, 0 ) ); drag->drag();
Note that the drag objects added to the multiple drag become owned by it. For that reason their parent should be 0.
