public static class FileDrop.TransferableObject extends Object implements Transferable
Transferable object,
use this class to wrap your object.
For example:
...
MyCoolClass myObj = new MyCoolClass();
Transferable xfer = new TransferableObject( myObj );
...
Or if you need to know when the data was actually dropped, like when you're
moving data out of a list, say, you can use the FileDrop.TransferableObject.Fetcher
inner class to return your object Just in Time.
For example:
...
final MyCoolClass myObj = new MyCoolClass();
TransferableObject.Fetcher fetcher = new TransferableObject.Fetcher()
{ public Object getObject(){ return myObj; }
}; // end fetcher
Transferable xfer = new TransferableObject( fetcher );
...
The DataFlavor associated with
FileDrop.TransferableObject has the representation class
net.iharder.dnd.TransferableObject.class and MIME type
application/x-net.iharder.dnd.TransferableObject.
This data flavor is accessible via the static
DATA_FLAVOR property.
I'm releasing this code into the Public Domain. Enjoy.

FileDrop.TransferableObject.Fetcher
Instead of passing your data directly to the
FileDrop.TransferableObject
constructor, you may want to know exactly when your data was received
in case you need to remove it from its source (or do anyting else to it). |
