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().
