DESCRIPTION
The QImageDrag class provides a drag-and-drop object for
transferring images.
Images are offered to the receiving application in
multiple formats, determined by the output formats in Qt.
For detailed information about drag-and-drop, see the
QDragObject class.
MEMBER FUNCTION DOCUMENTATIONQImageDrag::QImageDrag ( QImage image, QWidget * dragSource = 0,
const char * name = 0 )

QImageDrag::QImageDrag ( QWidget * dragSource = 0, const char *
name = 0 )
Constructs a default text drag object. dragSource must be
the drag source, name is the object name.

[static]
Attempts to decode the dropped information in e into img,
returning TRUE if successful.
See also canDecode().
bool QImageDrag::decode ( const QMimeSource * e, QPixmap & pm )
[static]
Attempts to decode the dropped information in e into pm,
returning TRUE if successful.
This is a convenience function that converts to pm via a
QImage.
