#1566 — Drag and drop to native b

  To: comp.lang.java.gui
Hi,

I tested the DragPictureDemo tutorial 
(http://java.sun.com/docs/books/tutorial/uiswing/dnd/intro.html#cut) on both 
Windows XP (32 bit) using JDK 6 and on Windows Vista (64 bit) using the Sun 
64 bit JDK (version 6).

The demo does not drop the images to an external application e.g. windows 
paint. I also tried dropping the images to Wordpad. In wordpad, I get a 
drop, however the "image" dropped into wordpad is just a black square.

I have also been trying to write my own code that will drop an image from a 
Java Swing application to an external app on Vista 64 (e.g. paint), however 
it does not seem to work.

Anyone else have a problem dropping images from a Swing app to a native app 
(e.g. paint)?

Any info would be appreciated!

Thanks.

Huh?  Which JNLP are you referring to?  This one?

Win XP Pro (..32 bit) JDK 6.

No.  It (the one I linked to) is sandboxed.  Pictures 
can be drag/dropped to blank squares withint the 
frame, but nowhere else.

Try this (also sand boxed) use of copy/paste between 
a web start app. and *external* native apps.
<http://www.physci.org/jws/#cbs>
I have been vaguely wonderring if it might be adaptable 
to D'n'D.  

Of course get the app. singed (digitally) and accepted
by the user with 'all-permissions' and you might use 
D'n'D how you would in an application launched from
the command line (w/ no security manager).

Maybe it is just lazy.   ;-)

Otherwise, if you can reduce that code as an 
SSCCE*, and post it here, complete with the 
copy/pasted stacktraces you are seeing, and 
we might be able to advise further.

Andrew,

Thanks for the response. I don't think it's a sandbox issue. I copied the 
source code from the demo link I specified and compiled and ran it as a java 
application and had the same problem.

My application is also run as a java app (not applet or web start) and has 
the same issue.

Thanks.

-Yugesh.

Your thanks can best be expressed, in your future lack
of top-posting..

This project?

That is odd.  Since you confirmed the app. was trusted,
I gave the classes in the archive (mentioned above) a 
quick run.

I could (on the aforementioned machine) paste pictures into
Paint Shop Pro 3.12 (an ancient version of a nice image editor)
and could D'n'D (or paste) pictures with Open Office 2 (Draw/Calc 
or Writer).

It got a little more interesting when I tried D'n'D to WordPad
and confirmed your result of 'blank image' arriving.  It got a 
little more interesting still when I discovered that I could 
see the images I had drag/dropped into OpenOffice, 
when copy/paste from OO into WordPad - as an 
actual image!

So in the same WordPad document, I had a blank image
D'n'D'd direct from DragPictureDemo2, beside a colored 
version that had come via OO.

A little bit of hunting led me here..
<http://www.rockhoppertech.com/java-drag-and-drop-faq.html#nativeimages>
Which leads me to think that whatever flavor these
images are being served up to (MS) Windows 
programs, it is not bitmap.  OO seems to handle 
whatever format the D'n'D offers - so does PSP.
