Re: Dragging an image from Webpage within Firefox no longer provides it as DataFlavour java.net.URL/java.util.List on OSX with Java 7

Hey Petr!
Thank! Please find the requested info below.
We’ve had numerous regression in datatransfer area in JDK-8 but wight now
they should all be fixed.
However the URI transfer on Mac OS X still does not work in some cases, it’s
simply not implemented.
I have a related issue: https://bugs.openjdk.java.net/browse/JDK-7124379
Could you please clarify
1. what exactly you are trying do drag
2. how you do it (do you select a text+picture or just picture or just drag
without selection)
3. which browser versions do you use
4. what result do are expect.
I’ll have a look at it and either fix it under an JDK-7124379 or file a new
CR for you.
1. (to make this easy) I'm dragging the OpenJDK image on
http://openjdk.java.net
2. Just the image, no text or anything else.
3. FireFox 26, Chrome 31 and Safari 7.0.1 on OS X 10.9.1.
4. I expect at least a
mimetype=application/x-java-url;representationclass=java.net.URL data flavor,
just like Java 6 provided. Additionally, I expect a
mimetype=image/x-java-image;representationclass=java.awt.Image, some
text/plain data flavors that allow me to retrieve the URL as String, and (I
guess) a text/uri-list data flavor, because it just makes sense.
The worst case is Chrome 31 -- Java build 1.8.0-ea-b121; only a
java.awt.Image is provided.
When dragging from Firefox 26, all flavors seem to occur 3 times.
According to the docs for Transferable#getTransferDataFlavors():
* Returns an array of DataFlavor objects indicating the flavors the data
* can be provided in. The array should be ordered according to preference
* for providing the data (from most richly descriptive to least
descriptive).
Unfortunately, I cannot recognize a meaningful ordering in Java 8.
I conducted a bunch of tests with the following source code:
import javax.swing.*;
import java.awt.datatransfer.DataFlavor;
import java.awt.datatransfer.Transferable;
import java.awt.datatransfer.UnsupportedFlavorException;
import java.io.IOException;
public class DragHere {
public static void main(String[] args) {
final JFrame frame = new JFrame();
final JPanel panel = new JPanel();
frame.getContentPane().add(panel);
panel.setTransferHandler(new TransferHandler(){
@Override
public boolean canImport(final TransferSupport support) {
return true;
}
@Override
public boolean importData(final TransferSupport support) {
final Transferable transferable = support.getTransferable();
final DataFlavor[] flavors =
transferable.getTransferDataFlavors();
for (final DataFlavor flavor : flavors){
try {
final Object transferData =
transferable.getTransferData(flavor);
System.out.print(flavor + :\t);
System.out.println(transferData);
} catch (UnsupportedFlavorException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
return true;
}
});
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
frame.setBounds(100, 100, 100, 100);
frame.setVisible(true);
}
});
}
}
When dragging the OpenJDK image on http://openjdk.java.net onto the panel, I
get the following output, showing supported flavors and their values for
different browsers and JVMs.

Re: Dragging an image from Webpage within Firefox no longer provides it as DataFlavour java.net.URL/java.util.List on OSX with Java 7
Hello, Hendrik.
Thank you for the great bug reporting.
The problem with ordering is known and it's tracked under:
https://bugs.openjdk.java.net/browse/JDK-8027148
As for the lack of DataFlavors - I've filed the following bug:
https://bugs.openjdk.java.net/browse/JDK-8031964
Also, thank you for noticing that something is wrong with the Finder. I think I
know the reason, but anyway I've filed
https://bugs.openjdk.java.net/browse/JDK-8031965
With best regards. Petr.

Have you verified the fix? When dragging a JPEG (which is not embedded in HTML) from a web browser to my app, I never get a URL or a File list flavor. What I reliably see is: java.awt.datatransfer.DataFlavor[mimetype=image/x-java-image;representationclass=java.awt.Image] and depending on the browser a bunch of other text/... flavors. But I'd much rather have a URL or a file... This is on OS X 10.9.1 and FireFox 26, Chrome 31 and Safari 7.0.1, Java build 1.8.0-ea-b121. Cheers, -hendrik I verified it was now working , but in my use case the jpeg is within the html file so maybe that is the difference paul

Dragging an image from Webpage within Firefox no longer provides it as DataFlavour java.net.URL/java.util.List on OSX with Java 7
So on Windows with Java 7 I receive an image dragged frrm a webpage in these flavours (plus others) but these are two I'm interested in 25/11/2013 10.31.07:com.jthink.jaikoz.draganddrop.FileDropTarget:drop:SEVERE: java.awt.datatransfer.DataFlavor[mimetype=application/x-java-url;representationclass=java.net.URL] 25/11/2013 10.31.07:com.jthink.jaikoz.draganddrop.FileDropTarget:drop:SEVERE: java.awt.datatransfer.DataFlavor[mimetype=application/x-java-file-list;representationclass=java.util.List] On OSX with Java 6 I received at least one of the two above, but now with Java 7 (1.7.0_40) I no longer receive either I found these bugs that seem related https://bugs.openjdk.java.net/browse/JDK-7124379 https://bugs.openjdk.java.net/browse/JDK-8005932 Could I have a comment on this please.
