[news.eclipse.platform.swt] Re: Drag n Drop Problem for TextTransfer in

[gottfried.huber@xxxxxx (paxdei1975)]

I solved the problem now, the CompilationUnitEditor obviously only accepts 
TextTransfers when I add DND.DROP_MOVE to the supported Drag operations (I 
only used DND.DROP_COPY before, now DND.DROP_COPY | DND.DROP_MOVE - though 
I never really would move the snippet)

Now there's another problem:

I would like to support both TextTransfer and FileTransfer: first one for 
dropping into TextEditor, latter for dropping into Navigator Folder (I 
create the file in tmp folder and pass the file name as dropevent.data).

works very nicely, only some (most) editors make problems as they somehow 
prefer FileTransfer over TextTransfer - with the result that only the 
filepath will be dropped into the editor.

I'm afraid there will be no real solution to it (i debugged into the swt 
source and got lost in OS and COM native calls....) so I will have to 
provide a seperate drag source widget explicitly for file dragging. That's 
not sexy but in times of need....

if anyone works on similar things and has found a better solution - please 
help
