[platform-swt-dev] Image Transfer Type

[Manuel SELVA <manuel.selva@xxxxxx>]

Hi all,

I am looking for a way to copy images (essentially for png) to the 
system clipboard in order  to be able to paste it in an other app. 
i found an old post about this :

> Currently there is no Image transfer type defined by SWT.  A platform
> specific, image type specific implementation is required to interact

> versus GTK BMP).

Is there any new thing (can't find anything .. so i suppose the answer 
is no but may be .... ) concerning this functionality ?

I just found an ImageTransfer (to transfer ImageData) class extenting 
ByteArrayTransfer, but all that class does is to create a byte array 
from the ImageData using  ImageLoader. Of course this doesn't work when 
i try to paste my image in word for example but MUST (i didn't test it) 
work to transfer ImageData between 2 SWT apps ....

Implement such a functionality means implement : PngImageTransfer.java 
for all SWT supported plateform using native call coming from OS.java, 
am i right ?
To succeed in such implementation, on windows in a first time for 
example, i also need to read Win32 PNG clipboard specific format in 
order to correctly provide the image to the native clipboard 
(implementation of javaToNative(ImageData ) ) ??
