helene did you check on pharo by example because hilaire wrote something on morph drag and dropping a while ago and we used it. I looked for my little example where I controlled a that a morph would on demand repel a drop or accept it. I did not check it but here it is Let me know if it is working for you. first in 1.4 and if you can adapt it for your need. On Aug 14, 2012, at 9:25 PM, Helene Bilbo wrote:
I already asked this on Stackoverflow, but as there were no answers, I post the question also here:
I want to build a Morph that accepts the dropping of files and folders onto it and that answers a new FileSystem FileReference for them in Pharo 1.4.
I found the class ExternalDropHandler and the wantsDropFiles: anEvent method in Morph, but it don't know how to put it all together, especially as ExternalDropHandler seems to work still with the old Files file system.
*What I did so far:* I made a subclass of Morph and implemented wantsDroppedMorph: aMorph event: evt, wantsDropFiles: anEvent and dropFiles: anEvent and set enableDragNDrop: to True. I open an instance in World and bring the Morph to the front. But, whenever I drop a file or folder onto it, it's the World, instance of PasteUpMorph, that get's to handle the drop (I found out by putting in some self halts) and not my Morph.
