Daniel,
it's possible. Look at swt snippet83, available at www.eclipse.org/swt
With a bit modified code you can see that, dragging a text provides you
with a String, while dragging an image provides with a path to image
file cached by the browser on disk.
To see this, let's change Snippet83.getNameFromId(int) to
getNameFromId(int,TransferData), and then modify the method so its part
will look like this:
case COM.CF_HDROP: // image
name = "CF_HDROP";
if (transferData != null) {
FileTransfer ft = FileTransfer.getInstance();
String[] r= (String[]) ft.nativeToJava(transferData);
name += " " + r[0]; // Append a path to file with image
}
break;
case COM.CF_TEXT: // text
name = "CF_TEXT";
if (transferData != null) {
name += " " +TextTransfer.getInstance().nativeToJava(transferData);
// append copied text
}
break;
Remember, to pass transferData in dragEnter(...) and null in constructor.
