Detailed Description
The Q3StoredDrag class provides a simple stored-value drag object for arbitrary MIME data.
When a block of data has only one representation, you can use a Q3StoredDrag to hold it.
For more information about drag and drop, see the Q3DragObject class and the drag and drop documentation.
Member Function Documentation
Q3StoredDrag::Q3StoredDrag ( const char * mimeType, QWidget * dragSource = 0, const char * name = 0 )
Constructs a Q3StoredDrag. The dragSource and name are passed to the Q3DragObject constructor, and the format is set to mimeType.
The data will be unset. Use setEncodedData() to set it.
Q3StoredDrag::~Q3StoredDrag ()
Destroys the drag object.
QByteArray Q3StoredDrag::encodedData ( const char * format ) const [virtual]
Reimplemented from QMimeSource::encodedData().
Returns the stored data in the format given.
See also setEncodedData().
const char * Q3StoredDrag::format ( int i ) const [virtual]
Reimplemented from QMimeSource::format().
void Q3StoredDrag::setEncodedData ( const QByteArray & data ) [virtual]
Sets the encoded data of this drag object. The encoded data is delivered to drop sites; it must be in a strictly defined and portable format.
The drag object can't be dropped (by the user) until this function has been called.
See also encodedData().
