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 DOCUMENTATION

QImageDrag::QImageDrag ( QImage image, QWidget * dragSource = 0, const char * name = 0 )
Constructs an image drag object and sets it to image. dragSource must be the drag source, name is the object name.

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.

QImageDrag::~QImageDrag ()
Destructs the image drag object and frees up all allocated resources.

bool QImageDrag::canDecode ( const QMimeSource * e ) [static]
Returns TRUE if the information in e can be decoded into an image.

See also decode().

Examples: desktop/desktop.cpp

bool QImageDrag::decode ( const QMimeSource * e, QImage & img ) [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.

See also canDecode().

Examples: desktop/desktop.cpp

QByteArray QImageDrag::encodedData ( const char * fmt ) const [virtual]
Reimplemented for internal reasons; the API is not affected.

const char * QImageDrag::format ( int i ) const [virtual]
Reimplemented for internal reasons; the API is not affected.

Reimplemented from QMimeSource.

void QImageDrag::setImage ( QImage image ) [virtual]
Sets the image to be dragged. You will need to call this if you did not pass the image during construction.
