List of all members.


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 Q3ImageDrag object and a K3URLDrag object), and bundle them together using K3MultipleDrag.

Sample code for this:

 K3MultipleDrag *drag = new K3MultipleDrag( parentWidget );
 drag->addDragObject( new Q3ImageDrag( someQImage, 0 ) );
 drag->addDragObject( new K3URLDrag( 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.

Deprecated:
use QMimeData instead

Constructor & Destructor Documentation

K3MultipleDrag::K3MultipleDrag ( QWidget *  dragSource = 0,
const char *  name = 0 
)

Create a new K3MultipleDrag object.

Parameters:
dragSource the parent object which is the source of the data, 0 for a parent-less object
name the name of the object, can be 0

Member Function Documentation

void K3MultipleDrag::addDragObject ( Q3DragObject *  dragObject  ) 

Call this to add each underlying drag object to the multiple drag object.

The drag object should not have a parent because the multiple drag object will own it.

Parameters:
dragObject the drag object to add. Should have no parent object.

Definition at line 31 of file k3multipledrag.cpp.

QByteArray K3MultipleDrag::encodedData ( const char *  mime  )  const [virtual]

Returns the data of a drag object with that supports the given mime type.

Parameters:
mime the mime type to search
Returns:
the data, or a null byte array if not found
Reimplemented from superclass.

Definition at line 42 of file k3multipledrag.cpp.

const char * K3MultipleDrag::format ( int  i  )  const [virtual]

Returns the i'th supported format, or 0.

Parameters:
i the number of the format to check
Returns:
the format with the number i, or 0 otherwise
Reimplemented from superclass.

void *  data 
) [protected, virtual]
