When using eg DataObjectComposite or a custom DataObject class with multiple formats, only the preferred format is populated
from the Clipboard.

Documented in tests/test_clipboard.rb.

Not a 2.0 blocker I think as it can be worked around by using DataObjectSimple to receive desired format. And it's pretty
esoteric functionality.

Hi Alex

Thanks for your answer. I gave it a new try, and found out that
using a custom data object (inheriting DataObjectSimple) in a
DataObjectComposite object did not place the custom data in the
clipboard.

When used with standard data objects (Text, Bitmap...) it works
as you just say: DataObjectComposite correctly places data in
the clipboard, but can't retrieve non preferred format.

I found a workaroud to place several custom data formats, by
simply inheriting the DataObject itself, and implementing the
few needed methods. Works like a charm to place data: replace
DataObjectComposite and DataObjectSimple with a simple
DataObject.

Thanks a lot for your help, and congrats' for this wonderful
lib !

Best regards,

Muriel

Hi Muriel

I believe it works fine for placing data on the clipboard - so
your custom data format is available to your app, but is also
available as text to other applications.

For fetching, I think the approach is to test is_supported? to
see whether the more advanced foramt is available, then fetch
it with an appropriate one-type data object. A bit clumsy but
should work.

Hi

I don't really understand the workaround.
DataObjectSimple supports only 1 format. I did not manage to
get it answer several formats.

This functionality is somewhat useful when your home made format
represents a text with additional metadata (kind of formatted
text). The metadata is only useful to your app, but the text
could be used in any application reading simple text from the
clipboard. In this case I don't see how I can work around this
missing behaviour.

Maybe I am missing something ?
