问题 I have been looking for examples of Drag and Drop with Java but they always use a generic mouse cursor with a box attached to indicate an item is being dragged, whereas many tools (even browsers like Firefox) instead attach a ghost of the dragged object to the cursor to indicate what is being dragged.

问题 I'm trying to create a DOCX in memory that I can provide for a Drag & drop operation. I first tried "Embed Source." However, while it seems to be perfect (DOCX in an OLE wrapper), Word does not use it for drag & drop although it does use it for cut & paste. Is there a way to force Word/Excel/PPT to use "Embed Source?" Second it uses FileContents sometimes and that also looks like it would work. However while Spy shows it being requested when Word does a drag/drop to Word, it doesn't work when
